The paper presents the results of studying the conversion of a mixture of toluene: straight-run gasoline (T: SRQ)= 1: 1, modeling the conversion of reforming gasoline, in the presence of a composite catalytic system Ni/HMOR/SO42/ZrO 2 (CCS) and its components, activating the joint hydrogenation of aromatic hydrocarbons and isomerization disproportionate transformation of C 8+ components. It has been established that at atmospheric pressure, Т= 180 0 С and the ratio Н2/hydrocarbon= 8, the transformation of the mixture with the participation of CCS is characterized by 76.8% conversion of toluene, 77.1% conversion of С 8+ components of SRQ and the 44.7% yield of isomeric С 5-С 7 alkanes. Based on a comparison of the results of the T: SRQ conversion in the presence of individual CCS components and their mechanical mixture, a conclusion was made about the conjugated nature of the effect of the CCS components on the process and a mechanism for the occurrence of catalytic synergy in the process of conversion of the T: SRQ mixture was proposed.

We address the methodology of a complex study of phase equilibria and thermodynamic properties in ternary metal and semiconductor systems using the emf method. A focus is on the behavior of partial molar functions in heterogeneous phase fields in the context of Voronin’s concept of partial heterogeneous functions (PHFs). The applicability criteria of emf measurements in heterogeneous phase fields for thermodynamic calculations have been determined. The scheme for calculating the integral thermodynamic functions (ITFs) of ternary phases from the partial molar functions of one component and the phase diagram using the integration of the Gibbs–Duhem equation has been described. Numerous thermodynamic data for ternary chalcogenide and chalcohalide systems gained by various variants of the emf method are cited.

Привлекательность водорода как универсального энергоносителя определяется экологической чистотой, гибкостью и эффективностью процессов преобразования энергии с его участием. Технологии разномасштабного производства водорода достаточно хорошо освоены и имеют практически неограниченную сырьевую базу. Однако низкая плотность газообразного водорода, низкая температура его ожижения, а также высокая взрывоопасность в сочетании с негативным воздействием на свойства конструкционных материалов ставят на первый план проблемы разработки экономически и технически эффективных и безопасных систем хранения водорода. Именно эти проблемы сдерживают развитие водородной энергетики и технологии в настоящее время. Предлагаемый обзор посвящен современным системам хранения водорода. Рассмотрены существующие технологии хранения водорода: физические и «химические» методы.

Химия низших алканов представляет собой одно из …
Химия низших алканов представляет собой одно из наиболее интенсивно развивающихся научных направлений [1—8]. В первую очередь это обусловлено необходимостью в большей степени использовать природный и попутный газы в качестве сырья для химической промышленности из-за неизбежного сокращения объемов добываемой нефти. Другой фактор связан со сложностью активации этих высокостабильных углеводородов. Термодинамические ограничения могут быть преодолены за счет использования реакций окисления углеводородов кислородом или соединениями, содержащими активный кислород. Однако при этом возникает проблема, связанная с протеканием реакций глубокого окисления и снижением селективности по целевым продуктам. Эта задача решается путем оптимизации условий парциального окисления и подбора катализаторов с высокой активностью, селективностью и стабильностью. В настоящем обзоре обсуждаются наиболее важные результаты по окислительной переработке низших алканов в синтез-газ и прямой конверсии метана в С2-углеводороды, что позволяет охарактеризовать современное состояние этой области химии и перспективы дальнейшего развития.

The review article is dedicated to a comprehensive study of the chemical bond formed during the immobilization of the proteolytic enzyme pancreatic trypsin in chitosan-based polymer matrixes and its derivatives. The main focus of the study is to describe the chemical bond that causes immobilization between chitosan based carriers and trypsin. Because the nature of the chemical bond between the carrier and trypsin is a key factor in determining the area of application of the conjugate. It has been found out that after the chemical nature of functional groups, their degree of ionization, the structure of the chemical cross-linking, the medium pH and ionic strength of chitosan are modified, the mechanism of trypsin immobilization is affected. As a result, the attraction enzyme to the matrix occurs due to polar covalent and hydrogen bonds, as well as electrostatic, hydrophobic, Van der Waals forces. The collected research …

This work is devoted to investigate the process of the electrochemical deposition of antimony from antimony oxychloride solution in the presence of tartaric acid in aqueous media. The kinetics and the mechanism of the electrodeposition process at the electrode surface are studied and proposed by the aid of cyclic, linear sweep voltammetric and chronoamperometric characterization methods. It is found that, the process is affected by the presence of tartaric acid and some factors during the electro-reduction process. The results also show that, the temperature, the potential sweep rate and the concentration of antimony have a great influence on the achievement of the electrodeposition process. Some important parameters are calculated such as, the activation energy of the electrochemical reaction, the diffusion coefficient and the number of saturated nucleation sites.

Novel bis-chelate HgII complexes with a series of 1-isopropyl-3-methyl-4-Naryl(alkyl)aminomethylene-5-thion(seleno)pyrazole derivatives (pyr(NR)X)2Hg of type (I) have been prepared. For the first time intramolecular reactions of tetrahedral inversion at the metal centre and degenerate ligand exchange reactions proceeding on the NMR timescale have been observed. The activation barrier of the inversion for the complex of type (I) with R = C6H11-cyclo, X = S has been found by use of dynamic 1H NMR spectroscopy (500 MHz) to be 54.3 kJ mol−1. For a series of complexes (I) the activation barriers against intermolecular ligand exchange processes lie in the range of 65–69 kJ mol−1. An X-ray study of (I) (R = C6H11-cyclo, X = S) revealed a pseudo-tetrahedral bond configuration of mercury, while the sulphur atoms demonstrate a tendency toward linear alignment with the angle SHgS' of 141.0° (1).

Abstract The Tl–TlI–Te ternary system was investigated by using the DTA and XRD analyses, microhardness and EMF measurements, leading to the construction of important polythermal and isothermal sections as well as the projection of the liquidus surface. Determined were the fields of primary crystallization and the types and coordinates of non-and monovariant equilibria. The system features the formation of continuous solid solutions (δ-phase) between the Tl 5 Te 3 and Tl 5 Te 2 I compounds. The homogeneity area of the δ-phase completely covers the Tl 5 Te 2 I–Tl 5 Te 3–Tl 2 Te subsystem. The partial molar thermodynamic functions (Δ G‾, Δ H‾, Δ S‾) of thallium as well as the standard integral thermodynamic functions of the Tl 5 Te 3− x I x solid solution (for various x) were calculated based on the results of the EMF measurements.

Hydrogenation of carbon–carbon multiple bonds is one of the most important processes widely used in chemical synthesis. We have shown for the first time that graphite-like carbon nitrides are capable of activating hydrogen molecules in the absence of any metals and can be successfully used as solid catalyst for the selective hydrogenation of phenylacetylene to styrene. This article presents the results of the investigation of the catalytic activity of mesoporous carbon nitride in the reaction of partial hydrogenation of phenylacetylene in the range of temperature 150–250 °C in the gas phase and at atmospheric pressure. The kinetic regularities of the reaction have been studied. A probable mechanism and the kinetic model of the reaction are formulated on the basis of the observed trends in the dependence of the initial rate from the temperature, concentration of phenylacetylene and catalyst mass.

Phase equilibria in the FeSe–Ga2Se3–In2Se3 system were studied by differential thermal analysis and X-ray powder diffraction analysis. A number of polythermal sections, the isothermal section at 1000 K, and the projection of the liquidus surface of the phase diagram were constructed. It was determined that this system is quasi-ternary, and that the liquidus surface comprises the fields of primary crystallization of six phases. The types and coordinates of invariant and monovariant equilibria were found. Wide regions of solid solutions based on binary and ternary compounds (FeGa2Se4, FeIn2Se4) were revealed, being of interest as magnetic materials.

Kinetic regularities of 4-phenyl-o-tolunitrile ammoxidation on V-Sb-Bi-Zr/γ-Al2O3 oxide catalyst in the temperature interval 633 - 673 K have been studied. It has been established that rates of conversion of 4-phenyl-o-tolu- nitrile into the aimed 4-phenylphthalonitrile and CO2 are described by half-order equation on concentration of substratum and to be independent of the oxygen and ammonia partial pressures. It has been revealed that formation of 4-phenylphthalimide from byproducts is due to hydrolysis of 4-phenylphthalonitrile; carbon dioxide is produced by oxidation of 4-phenyl-o-tolunitrile and decarboxylation of 4-phenylphthalimide, and 4-phenylben- zonitrile is produced from 4-phenyl-o-tolunitrile and 4-phenylphthalimide.

Antimony selenide (Sb2Se3), is an excellent photovoltaic …
Antimony selenide (Sb2Se3), is an excellent photovoltaic absorber due to its high absorption coefficient (> 105 cm-1) at the visible region and 1.17 eV band gap. In recent years, the power conversion efficiency of Sb2Se3 thin film solar cells has gradually enhanced. Therefore, given the great interest in this material, this work is devoted to the study of a mathematical model for the optimization of the preparation of thin Sb-Se films by the electrochemical method. The study was conducted by potentiodynamic, potentiostatic and galvanostatic methods carried out under different conditions at Pt, Cu and Ni electrodes. The kinetics and mechanism of the electroreduction of antimony and selenite ions in the tartaric acid were studied separately for the electrochemical deposition. On the basis of cyclic polarization, X-ray phase and SEM-EDX analyses, it is found that Sb-Se thin films are deposited on Pt and Ni electrodes, but not on Cu electrode. The mathematical calculations were performed in the OptimME software package using specially developed software for this process. By studying the effects of various factors (concentration of the initial components, temperature, current density, etc.), the optimal electrolysis mode and electrolyte composition for the co-deposition process were selected. Based on these results, Student and Fisher criteria were assigned for future purposes and regression coefficients were estimated. The obtained regression equation determines the electrolyte content and the electrolysis conditions, which allows precipitating the Sb-Se alloy containing the required amount of Sb. Calculations and experimental results show that the error …

In this study, the tracing of the electroreduction process of molybdate ions in aqueous media at different conditions is achieved for obtaining molybdenum metal in a simple and easy way. The kinetics and the mechanism of the electroreduction of molybdate ions are studied using cathodic polarization technique. It is observed that, the speed of the electroreduction process depends on the speed of the change of the cathodic potential sweep as well as on the temperature of the electrodeposition bath. Moreover, it is observed that, at the potential range from the stationary potential (Est= 0.25 V) to− 0.7 V, the electroreduction of molybdate ions occurs into two steps. Moreover it is observed that, after− 0.7 V the electroreduction process of molybdate is accompanying with evolution of hydrogen.

The work is devoted to the electrochemical co-deposition of iron and sulfur on Pt substrates from aqueous and nonaqueous electrolytes. The potential range of the single Fe and S and the bi-component Fe-S thin film electrodeposition is determined by applying the potentiodynamic polarization curves. The mechanism of the proceeding faradaic reactions on the surface of the platinum substrate is studied and identified in a broad potential range. The structure, stoichiometry, and morphology of Fe-S thin films deposited by potentiostatic and galvanostatic methods are determined using SEM, EDXA and X-ray phase analysis. The comparison of the results obtained in aqueous and nonaqueous electrolyte showed that Fe-S electrodeposition on the platinum substrate occurs by a similar mechanism in aqueous and non-aqueous electrolytes within a relatively broad potential range as in aqueous media, the process is facilitated due to the higher electrical conductivity of the electrolyte.

The Tl–I system has been studied using differential thermal analysis, X-ray diffraction, and emf measurements on TlI concentration cells. A more accurate Tl–I phase diagram is presented, according to which the compounds existing in the Tl–I system are TlI, Tl2I3, and TlI3. Thallium monoiodide melts congruently at 715 K and undergoes a polymorphic transformation at 440 K. The other iodides melt peritectically at 535 and 404 K, respectively. In contrast to what was reported previously, no compound of composition Tl3I4 has been obtained. Using experimental emf data, we evaluated relative partial molar thermodynamic functions of the TlI in alloys of the TlI–I system and the standard Gibbs free energy, enthalpy of formation, and standard entropies of TlI3 (−ΔG2980= 142.79 ± 0.73 kJ/mol, −ΔH2980= 135.37 ± 2.85 kJ/mol, and S2980= 263.3 ± 7.4 J/(mol K)) and Tl2I3 (271.39 ± 1.47, 262.40 ± 5.34, and 322.8 ± 13.2).

We carried out thermodynamic study of the TlInSe2-TlGaTe2 system based on the data of physicochemical analysis. Based on thermodynamic analysis and concentration dependence of physical properties, it was found that there is anion-cation substitution in TlInSe2-TlGaTe2 system. Continuous series of (TlInSe2)1-x (TlGaTe2)x solid solutions is forming throughout entire concentration range. We determined dielectric characteristics of samples, their frequency dispersion and nature of dielectric losses. The results demonstrate that the dielectric dispersion in the studied crystals TlInSe2 and (TlInSe2)0.5(TlGaTe2)0.5 has a relaxation nature. Hyperbolic decline of loss tangent with increasing frequency from 50 kHz to 35 MHz indicates the loss of pass-through conduction in (TlInSe2)1-x(TlGaTe2)x solid solutions.

In recent years, a great interest has been emerged on electrochemical preparation of semiconductor films based on selenium. Therefore, a study of electrochemical reduction of selenium could be very important. In this work, the kinetics and mechanism of the electrochemical reduction of selenite ions on the Pt cathode have been studied in the electrolyte containing selenious and tartaric acids. The study shows that electroreduction of selenite ions from tartaric electrolytes proceeds in two stages. The effect of various factors on the cathodic reduction of selenium ions has also been studied. The effective activation energy was calculated using the polarization curves of the temperature dependence of the electroreduction process of selenite ions. It was established that the process of electroreduction under investigation is proceeding by mixed kinetics, at first by concentration and then by electrochemical polarization.

В Институте органической химии им. НД Зелинского РАН,(ИОХ РАН) для процесса получения синтез-газа из попутного нефтяного газа (ПНГ) разработаны эффективные оксидные катализаторы, содержащие до 20 мас.% активного кислорода. Восстановленные системы полностью регенерируются при последующей обработке воздухом. Структурные свойства этих систем были изучены РФА-методом. Было установлено, что размер частиц металлов и их оксидов не превышает 35 нм, что является необходимым условием для достижения обратимости окислительно-восстановительных переходов. Процессы регенерации восстановленных систем, не содержащих и содержащих кокс, изучены методом ТГ-ДТА в атмосфере воздуха. Показано, что эффективными окислителями являются также диоксид углерода и пары воды. Использование разработанных систем открывает новый путь одновременной переработки углеводородов ПНГ в синтез-газ. При этом резко снижаются энергозатраты, отпадает необходимость дорогостоящего выделения кислорода из воздуха, исключается образование взрывоопасных смесей.

Complex copper-based chalcogenides are a significant environmental-friendly …
Complex copper-based chalcogenides are a significant environmental-friendly functional material that has great application potential due to their interesting thermoelectric, photoelectric, optical, and other properties, as well as their ionic conductivity. Analysis of numerous studies shows that improving the application characteristics of these compounds is associated with manipulating their structure and composition. An effective solution for optimizing such processes requires their in-depth thermodynamic analysis, which requires reliable data on the fundamental thermodynamic characteristics of the corresponding compounds. This review summarizes the results of researches, including ours works, on the thermodynamic properties of copper chalcogenides with some p1 -p 3 elements. The majority of these works were carried out using various modifications of the electromotive force (EMF) method. Planning of experiments carried out by this equilibrium method of chemical thermodynamics and processing of their data is impossible without the presence of reliable data on phase equilibria. Taking this into account, in addition to thermodynamic data, the work also presents the solid-phase equilibria diagrams for a number of systems studied by the EMF method. The analysis showed that for the Cu-Tl-X, Cu-Ge(Sn)-X (X-S, Se, Te) and Cu-As(Sb, Bi)-S(Se) ternary systems there are mutually consistent data on the phase equilibria and thermodynamic functions of the ternary compounds. For the Cu-Tl-X and Cu-Sn-Se systems, the thermodynamic functions of ternary compounds are obtained by two modifications of the EMF method by determining the …

New platinum nanocomposites were synthesized by chemical reduction of H2PtCl6•6H2O in situ with a methanol—water mixture using mesoporous carbon nitride as a stabilizing matrix and a catalyst support. The textural, morphological, and optical properties and the structural and phase composition of the composites were studied by low-temperature nitrogen adsorption—desorption, scanning electron microscopy, photoluminescence, IR, and UV spectroscopy, powder X-ray diffraction, and inductively coupled plasma atomic emission spectrometry. The introduction of metal particles did not induce significant changes in the structural integrity and, hence, in the specific physicochemical properties of mesoporous carbon nitride. The catalytic activity of the synthesized nanocomposites was evaluated in the hydrogenation of phenylacetylene, styrene, and cyclohexene.

The sorption of doxorubicin by hydrogeles obtained through cross-limking of polyacrylic acid with varied quantity (%, mass) of N, N-methylene-bis-acrylamide within pH= 1÷ 10 interval for 24 hours was performed. It revealed that protonation of active functional groups of hydrogel in acidic media (pH≤ 4) impedes electrostatic interaction with identical charges in hydrogel and doxorubicin. A small degree of swelling at low pH of medium also impedes the penetration of molecule of antibiotic into internal pores of hydrogele. Note that pH changes toward alkaline medium, deprotonation and thereby negative charging of hydrogele surface leads to the sorption of positively charged molecule of doxorubicin. As the pH changes to the alkaline, the deprotonation of the hydrogel surface and, on the contrary, the negative loading that causes the easy sorption of positively charged doxorubicin molecule.. On the other hand, the high swelling of hydrogel in alkaline medium also contributes to the increase of sorption level. Also, the nature of chemical interaction between hydrogel and antibiotic was examined by infrared spectroscopy methods, as well as by scanning electron microscopy. It found that the relation between the polymer and the doxorubicin occurs mainly due to hydrogen bond, electrostatic and hydrophobic interaction.

To create a catalytic system for low-temperature isomerization of a mixture of normal and low-branched alkanes, conversion of n-butane, n-hexane and their mixture (mole ratio 1: 1) was studied using a catalytic system Ni/MOR-SO4 2–/ZrO2 and its components. It was shown that the combination of properties of Ni/MOR and SO4 2–/ZrO2 can decrease the temperature of the isomerizing catalyst below 150 C. The combined isomerization of n-butane and n-hexane provides an increase in the conversion of n-butane with the formation of isopentane and a decrease in the conversion of n-hexane as compared with the conversions obtained during their separate transformation. Thus, the combined isomerization can increase the octane number of straight-run gasoline fractions as a result of averaging their molecular weight because of the accumulation of isopentane.

Literature data dedicated to formation of 4-phenylphthalonitrile were analyzed and generalized. As a result of the own studies, it has been established that on V–Sb–Bi–Zr/γ-Al2O3-oxide catalyst ammoxidation gives 83.10 mol.% 4-phenylphthalonitrile at high conversion of the initial 4-phenyl-o-xylene in a single process. In connection with increased demand to purity of 4-phe-nylphthalonitrile at using and division problem of hard-separable impurity of crystal 4-phe-nylphthalimide, a variant of the technological process design with average conversion and recirculation of the unreacted 4-phenyl-o-xylene and intermediate 4-phenyl-o-tolunitrile was proposed. In contrast to the single process, it has been determined that recirculation reduces quantity of form by-products, fractions of deep oxidation and increases selectivity on 4-phenylphthalonitrile up to 96.14% - 97.72%.

The state phase diagram of the Li2O⋅2B2O3-Yb2O3⋅B2O3 section is an eutectic system with invariant eutectic point corresponding to ∼0.2 mole fraction of Yb2O3⋅B2O3 and 800 °C. According to physico-chemical analysis, the Li2O⋅2B2O3-Yb2O3⋅B2O3 polythermal section is quasi-binary, allowing us to partially triangulate the Li2O-B2O3-Yb2O3 system. The borders of the glass formation region were defined in the Li2O⋅2B2O3-B2O3-Yb2O3⋅B2O3 concentration triangle. The vitreous samples showed a semiconducting nature.

Nanoparticle formulation development for drug delivery, a …
Nanoparticle formulation development for drug delivery, a crucial aspect of nanotechnology, encounters numerous challenges. These encompass selecting appropriate excipients, comprehending miscibility and solubility factors, ensuring efficient drug encapsulation and release, assessing stability, and facilitating drug transport in the bloodstream for accurate targeting and attachment. To address these intricate issues, a range of molecular computational models is utilized. These models include quantum mechanical simulations that handle the smallest particles and move through atomistic molecular dynamics for detailed molecular interactions, coarse-grained molecular dynamics (MD) for larger scale phenomena, and dissipative particle dynamics (DPD) for mesoscale modeling. Further scaling up, computational fluid dynamics (CFD) is used for fluidic behaviors, discrete element modeling for large particle systems, and both pharmacokinetic/pharmacodynamic (PK/PD) and physiologically based pharmacokinetic (PBPK) modeling for whole-body dynamics. These methodologies play a crucial role in elucidating the complex mechanisms involved in the development of nanoparticle formulations and are essential in the creation of varied organic and inorganic systems for drug delivery. This review primarily concentrates on these computational simulation models and their significance in the context of nanoparticle-based drug delivery systems.

An analysis of the behavior of non-Newtonian oils in the process of formation and destruction of their structure with the participation of resinous-asphaltenic materials has been performed. The conditions of formation of coagulation structures and the possibilities of their destruction were determined. A general rheological equation defining the possible behavior of non-Newtonian oils in different cases has been derived, and its effectiveness was substantiated with the use of available experimental data. The dependences of the effective viscosity of non-Newtonian oils on the rate of their shear and the content of resinous-asphaltenic materials in them were constructed. It was established that the asphaltenes, resins, and paraffins, contained in an oil, substantially influence its rheological properties and, consequently, the movement of the oil and its transportation.

The process of co-deposition of Ni with …
The process of co-deposition of Ni with Mo from alkaline electrolytes was studied by taking linear and cyclic polarization curves of Pt electrode at various concentrations of initial components and potential scan rates. Solutions of Na2MoO4∙ 2H2O and NiSO4∙ 7H2O were used as sources of ions of the main components in NH4OH electrolyte. It was found that co-deposition of nickel with molybdenum goes through the oxide formation stage, and a solid solution of these two metals is deposited on the cathode surface. The film obtained at constant current on Ni electrode under optimal conditions was found amorphous, but additional thermal treatment at 500 C for one hour made it polycrystalline. This was confirmed by peaks in X-ray diffraction patterns, corresponding to NiMoO4, Ni, and MoO3. The proposed electrolyte and electrolysis conditions allow to obtain thin films with molybdenum content ranging from 17.1 to 50.9 at.%. The co-deposition of Ni with Mo is limited by diffusion of these ions to the cathode surface. The knowledge of the mechanism of co-deposition of Ni and Mo will make possible a selection of optimal conditions for deposition of alloys of the required composition with satisfactory electrocatalytic properties.

The influence of the quantitative composition of the electrolyte and galvanostatic electrolysis conditions on the composition of thin Bi2Se3 semiconductor films electrochemically deposited in the galvanostatic mode from a solution of Bi(NO3)3·5H2O and H2SeO3 in ethylene glycol was studied. The results show that, with an increase in the current density and H2SeO3 concentration, the bismuth content of the thin films decreases. As the electrolyte temperature, Bi(NO3)3·5H2O concentration, and electrolysis time are increased, the bismuth content of the thin films increases. The optimum electrolyte composition and electrochemical deposition conditions for obtaining thin Bi2Se3 films of the composition close to stoichiometric were determined.

The studies of interaction of synthetic polymers …
The studies of interaction of synthetic polymers with transition metal ions have attracted much attention from scientists. This is due both to theoretical aspects that take into account the impact of the transition metal on the conformation of the polymer chain, and for applied aspects related to the creation of new specific ions for the extraction of a strictly defined metal from the mixture, the creation of new polymer catalysts, etc. Most of the work on the interaction of metal ions with macromolecules of cross-linked polymers is devoted to the study of equilibrium in a polymer-ligand-metal mixture. It can be considered firmly established that the interaction of transition metal ions with polymer ligands can be described in terms of chemical equilibrium. Depending on the chemical structure of the polymer and the type of transition metal ion, the equilibrium can be shifted both towards the formation of the reaction product-polymer-metal complex, and towards the interacting components.For a number of systems, a polymer transition metal ligand ion, for example, for systems: poly-4-vinylpyridin-Ni and poly-4-vinylpyridin-Mn, the processes of cooperative binding of a metal ion with a polymer chain are observed. The reason for the cooperative binding, most likely, is the conformational changes in the ligand macromolecules that occur during its interaction with the complexing agent. Nevertheless, in the literature, issues related to the change in the properties of the polymer chain during its interaction with the complexing agent have not yet been considered sufficiently deeply. But precisely this question is of great importance for the description of the properties of polymer …

On the basis of kinetic data of 4-phenyl-o-xylene and 4-phenyl-o-tolunitrile ammoxidation, formation mechanism of the products was analyzed and generalized. It has been shown that dissociative adsorption of a substrate and mononitrile occurs on the centers with high heats of adsorption of oxygen and as a consequence, completely covered with it, competitive adsorption of NH3 and O2 occurs on the centers with low heats of adsorption of the latter; mononitrile and dinitrile are formed correspondingly from adsorbed fragments of both substrate and NH3, and tolunitrile and NH3; surface interaction of adsorbed fragments of substrate and O2 with low heat of adsorption gives imide and CO2; hydrolysis of dinitrile into imide occurs on centers completely covered with ammonia; imide decarboxylation occurs on the centers covered with it; oxidative destruction of tolunitrile occurs on centers covered with substrate and mononitrile.

Утилизация попутного нефтяного газа (ПНГ) является одной …
Утилизация попутного нефтяного газа (ПНГ) является одной из приоритетных задач, стоящей перед нефтегазовым комплексом России. Одним из путей решения этой задачи является конверсия ПНГ в синтез-газ с последующей переработкой в моторные топлива, метанол и другие ценные продукты непосредственно на нефтепромыслах. В Институте органической химии им. Н.Д.Зелинского РАН созданы наноструктурированные оксидно-металлические системы, в которых частицы активных компонентов имеют размер менее 35 нм. Это является необходимым условием высокого содержания активного кислорода (18-20 мас.%), который способен окислять углеводороды в синтез-газ: CFU + МеОм = 2Нг + СО + МеО*. Последующая обработка воздухом полностью регенерирует восстановленную систему, т.е. повышает содержание активного кислорода до исходного уровня и удаляет образовавшийся углерод: МеОх + 0,50г (воздух) = MeO»i + азот; С + Ог = СОг. Разработанный метод конверсии ПНГ в синтез-газ имеет следующие преимущества: резкое снижение энергозатрат; использование воздуха в качестве окислителя (а не чистого кислорода) без разбавления азотом получаемых смесей (НЬ+СО); исключение образования взрывоопасных смесей углеводороды-кислород.

MnNaW/SiO2 oxide system based on a mesoporous silica matrix synthesized using tetraethoxysilane and cetyltrimethylammonium bromide as precursors were prepared and characterized by SEM/EDS, XRD, EPR, N2 adsorption-desorption measurements and studied in the oxidative conversion of methane (OCM). It is shown that MnNaW/SiO2 catalyst consists of MnOx, Na2WO4, MnWO4, and SiO2 phases. At the reaction temperature of 750-850°C the molten Na2WO4 phase covers the surface of crystalline SiO2, and the interaction of MnOx, Na2WO4 and SiO2 matrix forms “liquid glass”. It is assumed that Na1–yMnOx particles formed as a result of the interaction of the system components during catalyst formation and characterized by the presence of ion-radical lattice oxygen are catalytically active sites in the OCM process.

The reactions of liquid - phase oxidation of aliphatic oxygen containing hydrocarbons, in particular, nonanol - 4 and nonanon - 4 in the presence of polyethylene - polyamine complexes (PEPA) with sorbated ions of metals with changeable valency (Co2+,Cu2+, Ni2+) were studied. It revealed that the oxidation of nonanole-4 and nonanone - 4 in the presence of Cu2+ and Ni2+ ions in the analyzed system is less active while in the presence of Co2+ ions decarboxylation of acids it is practically absent and it leads mainly to formation of carbonic acids. It has been established that the character of oxidation reaction mostly depends on the properties of metals fixed on polymer matrix.

The paper presents the results of a study of solid-phase equilibria in the Tb-Te system and the thermodynamic properties of terbium tellurides obtained by the methods of electromotive forces and X-ray diffraction analysis. Based on the experimental data, it was established that the TbTe, Tb2Te3, TbTe2 и TbTe3 compounds are formed in the system. For the investigations of the alloys from the two-phase regions TbTe3+Te, TbTe2+TbTe3, and Tb2Te3+TbTe2, the EMF of concentration cells relative to the TbTe electrode was measured. The EMF of concentration cells relative to the terbium electrode was measured for the TbTe+Tb2T3 region. The partial thermodynamic functions of TbTe and Tb in alloys were determined by combining the EMF measurements of both types in the 300-450 K temperature range, based on which the standard thermodynamic functions of formation and standard entropies of the indicated terbium tellurides were calculated.

The appearance of eight methyl groups in each reagent of the redox-system of Ме8Fс+/0 increases the constant of exchange rate approximately 4.8 times, in comparison with the unsubstituted ferrocene-ferricinium system [(С5Н5)2Fe/(С5Н5)2Fe+PF6] (Fс+/0). The increase of exchange rate in series of Fс+/0Ме6Fc+/0Ме8Fс+/0Ме10Fс+/0, though it corresponds to the electron donor property of the methyl group, is interpreted by us as the result of reduction of reorganization energy of solvent molecule (acetone) by increasing the reagent volumes of the redox couples of МеnFс+/0 (n = 6, 8, 10).

Kinetic regularities of liquid-phase oxidation of cyclohexanone in the presence of copper and cobalt complexes with polyethylenimine (PEI) stitched and carboxyl resin. It revealed that the rate of reaction increases by far in the presence of copper complexes with PEI stitched at 140 degrees C The same is true in case cobalt complex presence with PEI stitched. If carboxyl resin CB-4P2V is used as carrier, catalytic activity of cobalt complexes is much higher than copper-containing complexes. Optimal concentration of the catalyst has been identified whose increase results in inhibition of reaction rate.

The systems of indium tin oxide (ITO)/nano-porous anodized aluminum oxide Al2O3 (AAO) and ITO/CdS nano-structured were fabricated on transparent glass substrates by using radio frequency magnetron sputtering and electrochemical deposition. The glass/ITO/AAO samples were transparent for visible light that make them useful and efficient for PV solar cell applications. The effect of annealing on optical and electrical properties of ITO thin films has been studied. It is found that, the transparency of the ITO films is directly proportional to the oxygen content of the plasma in the sputtering chamber and increased with annealing temperature, while the sheet resistance is inversely proportional to the annealing. In this work, it is found that, the electrochemically fabricated CdS thin films nanostructure of thickness of 200–500 nm is transparent and well absorbs the light over the wavelength wide ranged from 450 to 800 …

Показано, что сочетание свойств Ni/MOR и SO 2-/ZrO позволяет снизить рабочую температуру изомеризующего катализатора ниже 150 С. При совместной изомеризации н-бутана и н-гексана конверсия н-бутана увеличивается с образованием изопента-на, а конверсия н-гексана уменьшается по сравнению со значениями, полученными при их раздельном превращении. Это позволит увеличить октановое число фракций прямогонных бензинов вследствие усреднения его молекулярной массы за счет накопления изопентана.

The catalytic activity of promoted form of H-mordenite (HM) sharply increases in conversion of n-butane after dealumination and promotion by zirconium dioxide and sulfate-ions. Catalysts SO42−/ZrO2/HM prepared by impregnation method using ZrO(NO3)2 and (NH4)2SO4 show an activity in n-butane conversion already at 403 K. The simultaneous formation of propane, isobutane, isopentane and the symbiotic change of their yields with time indicate to the reaction passing over promoted mordenites on biomolecular mechanism. The samples SO42−/ZrO2/Al2O3 and SO42−/ZrO2 prepared by impregnation of salt ZrO(NO3)2 calcined at 823–873 K with (NH4)2SO4 solution practically are not active in the process of isomerization of n-butane that points to an important role of HM in the investigated catalytic systems.

Oxidation of n-octane was carried out in a stationary reactor using immobilized manganese nanoparticles in various mass percentages (5 and 10 wt.%) on poly(4-vinylpyridine). It was found that manganese-containing catalysts immobilized in polymer are more active in the oxidation of n-octane than similar homogeneous catalysts. A kinetic model and an equation for calculating the oxidation of n-octane in the presence of a manganese-polymer catalyst were chosen for the calculation. Taking into account the kinetic model, the velocity constant of the specified process is calculated. A high conversion in the oxidation reaction of n-octane with molecular oxygen was obtained

Iron - and copper - containing oxide catalysts have been synthesized by sol - gel technology with autocombustion using organic reagents - citric acid, glycine, urea as a complexing agent and "fuel"; studied their activity in the oxidation of carbon monoxide to dioxide. The obtained samples were characterized by the methods of X - ray powder diffraction, infrared spectroscopy and electronic paramagnetic resonance, the texture characteristics of these samples was determined by measuring the specific surface area. It is shown that, regardless of the preparation method, all synthesized samples are mixtures of iron oxides Fe 2O3, copper CuO, and copper ferrite CuFe2O4. It was found that the nature of the organic reagent affects the catalytic activity of the synthesized catalysts. On a catalyst with a Cu:Fe=1:1 ratio, prepared by the sol - gel method with autocombustion using urea, the complete conversion of CO is achieved at 130°C. The same catalyst, synthesized with citric acid, is active at 250°C and on a catalyst prepared using glycine, complete conversion of CO occurs at a higher temperature of 350°C. It is assumed that the different nature of combustion leads to the formation of different surface morphology and texture, which ultimately determines the catalytic activity. Thus, the most catalytically active sample was obtained using urea as a "fuel" has a higher specific surface area (25 m2 / g) than the other two samples (for the samples obtained with citric acid and glycine, the specific surface area is 9 m2 / g and 5.8 m2 / g, respectively).

Catalysts with manganese nanoparticles (5 and 10 wt %) immobilized on poly-4-vinylpyridine were prepared. When interacting with molecular oxygen, the catalyst forms active oxygen, which is involved in the low-temperature oxidation of n-heptane. These catalyst compositions have been used to oxidize n-heptane with pure oxygen to give alcohols, aldehydes and ketones. Oxidation of n-heptane was carried out in the temperature range 303-383 K, molar ratios of heptane:oxygen = 1:3.38, and at atmospheric pressure. It has been found that the non-crosslinked (MnP4VP polymer poly-4-vinylpyridine) and N,N¢-methylene-bis-acrylamide-crosslinked MnP4VP/MBAA metal-polymer catalyst containing 5 wt % Mn2+ exhibits the highest activity in n-heptane oxidation reactions. The kinetic parameters of the reaction of n-heptane oxidation with oxygen at low temperatures were studied using a kinetic model based on the heptane conversion data. The kinetic model was compiled on the basis of experimental data: heptane:oxygen = 1:3.38 at atmospheric pressure using Mn (wt. 5%) P4VP/MBAA in the temperature range 303-383 K. Within the framework of the chosen kinetic model effective rate constants of the oxidation reaction with the formation of alcohols was calculated

The crystal structure of 1,2,4,1′,2′,4′-hexamethylferrocene (Me6Fcsym) was determined by X-ray diffraction. In the Me6Fcsym molecule, the C5 rings occur in the staggered conformation. The Fe–(C5 ring center) bond length tends to increase in the series Me2Fcsym, Me6Fcsym, Me8Fcsym, and Me10Fcsym. The relative conformations of the vicinal Me groups in the Me6Fcsym, Me8Fcsym, and Me10Fcsym molecules and the pattern of variation of the 1H and 13C NMR signals of the Me groups in the series of polymethylferrocenes MenFcsym (n = 2, 4, 6, 8, 10) compared with the methylbenzene analogues indicates that Me groups in symmetric polymethylferrocenes are not coupled, but are relatively free to rotate around the C(C5 ring)–C(Me) bond (CIF file CCDC no. 1436882).

The conversion of straight-run naphtha on composite catalytic systems containing HZSM-5 zeolite modified with 0.4 wt % Co or Ni and 15% SZ (10% SO42-/ZrO2), performed at atmospheric pressure in the interval 140–200°C, was studied. At 140–200°C, the major products of straight-run naphtha conversion are branched C5−C6 alkanes. At T ≥ 180°C, the reaction products become enriched in gaseous alkanes. Analysis of the conversion products suggests that the process occurs via formation of a skeleton-isomerized intermediate, followed by its cleavage (disproportionation) at the β- or α-bond. The conversion is influenced by the conditions of the reaction and reduction of the composite catalytic system. On the Co-containing composite catalyst reduced at 380°C, the conversion of C8+ components of straight-run naphtha at 180°C, feed space velocity of 2.5 h−1, and H2/CH = 3 is 76.8%, and the content of C5−C6 …

In our study, new natural-synthetic, cross-linked copolymers were obtained by radical copolymerization of chitosan in the presence of 4-vinylpyridine and N-vinylpyrrolidone. In order to cross-link 4-vinylpyridine and N-vinylpyrrolidone to chitosan, the radical co-polymerization with azobisanobutyronitrile initiator were performed in the homogeneous phase in the presence of monomers. The combined effects of the major parameters to the cross-linked radical copolymerization were studied systematically. The cross-linking degree of the monomers to chitosan (G) and dependence of crosslinking effectiveness (E) upon temperature, amount of chitosan, concentration of inisiator, solvent ratio, reaction time and concentration of monomers were studied. It revealed that G = 258% and E = 17-19% were max. at 60-700C, within 150 min., in the cross-linked copolymerization of 0.35 g chitosan with 2.4 mol/l of N-vinylpyrrolidone and 0.2 mol/l of 4-vinylpyridine in the presence of 75 ml 2% CH3COOH as a solvent, and the estimated degree of homopolymerization at minimum 18-20%. Through the use of :H NMR, FTIR, SEM, X-Ray and thermogravimetric analysis methods, the mechanism of radical crosslinked copolymerization was proposed on the basis of the cyclic breakdown of chitosan.

The conversion of n-C7H16, n-C4H10 and their mixtures C7H16:(H)-C4H10= 1:0,3 have been studied on composite catalysts Al2O3/WO42-. ZrO2 (A-WZ) and HMOR/ WO42-. ZrO2(M-WZ) at atmosphere pressure,.2/ hydrocarbon= 3 and at temperature 140-200 degrees. It revealed that A and M have no effect on isomerization and hydrocracking reactions of n-C7H16 on A-WZ and M-WZ. Note that the mixture of n-C7H16: n-C4H10 with its high selectivity is conversed into isomers of C5-C6. An assumption has been advanced about the activation mechanism of bimolecular C-11 intermediate which precedes the formation of reaction products.

In alkali environment hydrogels with high swelling ability have been synthesized as a result of cross-linking well water soluble and non-toxic polymer - polyacrylic acid (Mη=230 kDa) with 5, 10, 15 and 20% ratio (by weight) of N,N`-methylene-bis-acrylamide. Absorption processes of obtained hydrogels with doxorubicin hydrochloride from water environment have been researched. Dependence of sorption degree and sorption capacity of antibiotic on environment pH and starting concentration of doxorubicin has been researched and nature of chemical interaction between hydrogel and antibiotic has been found out via infrared, ultraviolet, nuclear-magnet resonance spectroscopy methods. It was determined that in pH=8 hydrogel taking 10% cross-linking reagent inside has 570% swelling degree and with increasing environment pH sorption capacity increases up to 13.4 mg/g as per doxorubicin of gel. It was investigated with UV, FTIR and NMR spectroscopy methods that interaction hydrogel with antibiotic occurs due to hydrogen bonds and electrostatic forces.

При высоких степенях активности катализаторов, приготовленных на основе цеолитов Y, M и ZSM-5 изучены зависимости выходов продуктов дегидроциклоароматизации алканов C 2+, изомеризации н-пентана и диспропорционирования толуола от кислотных и микропористых характеристик модифицированных цеолитов. На основе полученных и литературных данных показано, что исходная активация молекул реактантов происходит на кислотных центрах независимо от их кислотности, а образование и перераспределение C C-связей лимитируются молекулярно-ситовыми параметрами цеолита и регулируются модифицированием исходных цеолитов, на основе которых синтезированы катализаторы.

Over the past few decades, a significant increase in the use of heavy metals has led to an increase in the amount of metals in the aquatic environment. For living organisms, among heavy metals, copper (II) is one of the toxic metals and one of the most common environmental pollutants. Excessive concentrations of Cu2+ ions can cause various diseases and intoxications in humans. In this regard, the use of absorbents for the sorption of metals is both an economically and technologically efficient method. Quaternized natural polymer chitosan was used as a sorbent to study the sorption properties of copper (II) ion. During the research, the optimal conditions of the sorption process was determined, pH effect of the environment, initial concentration of the metal on the sorption process were studied. The sorption capacity of the synthesized sorbent towards the Cu (II) ion was studied and it was determined that the maximum sorption capacity equal to 255 mg/g was at pH=4. Moreover the influence of copper (II) ion concentration on the sorption process was studied. It was found that the sorption capacity and sorption degree of the sorbent increase with an increase in the concentration of the Cu2+ ion in the solution. It was determined that the maximum sorption capacity was 406 mg /g, which corresponds to the concentration of copper (II) ion, equal to 10∙10ˉ² mol/L. The results show that quaternized chitosan-based sorbent can be successfully used for the sorption of Cu (II) ion.

The phase equilibria of the Sb2Te3+2BiI3↔Bi2Te3+2SbI3 reciprocal …
The phase equilibria of the Sb2Te3+2BiI3↔Bi2Te3+2SbI3 reciprocal system have been investigated over the entire concentration range using differential thermal analysis (DTA), powder X-ray diffraction (PXRD), and scanning electron microscopy (SEM) techniques. Liquidus surface projection, solid-phase equilibrium diagram at 300 K and a number of isopleths sections of phase diagram were constructed based on experimental results and literature data. The primary crystallization areas of all the existing phases, their homogeneity ranges, as well as, types and coordinates of non- and monovariant equilibria were revealed. It is determined that the BiTeI−SbTeI section of this reciprocal system is non-quasi-binary due to the incongruent melting of one of the initial ternary compound. However, it is stable at subsolidus and forms wide areas of solid solutions based on the initial compounds. Additionally, dielectric …

The work is devoted to the electrochemical deposition of Sb–Se thin semiconductor films and the determination of the effect of the main factors on the composition of the obtained films. The effect of the electrolyte composition, temperature, current density, etc., on the composition of Sb–Se thin films electrodeposited from an ethylene glycol electrolyte, has been studied to find the optimal composition of the electrolyte and the electrolysis mode. The results of the experiments showed that with an increase in the concentration of H2SeO3, the amount of antimony in the obtained films decreases. An increase in the electrolysis time up to 15 h positively affects the composition of the deposited films. Depending on the current density, the amount of antimony in the composition of the deposited films increases, and high-quality films are formed at a current density of 0.19 mA/cm2. The amount of antimony and selenium in …

Immobilization of a thyroid hormone substitute of …
Immobilization of a thyroid hormone substitute of L-thyroxine on chitosan-based smart hydrogel structure was performed to reduce the side effects of the required daily dose. The hydrogel was obtained by the Schiff reaction of chitosan with acetaldehyde and quaternization with methyl iodide then by ion exchange with NaCl salt. Finally, a hydrogel was obtained from the treatment of chitosan-based salt at -200C. The amount of levothyroxine immobilized by physical sorption on the hydrogel was determined by molecular electron spectroscopy on basis especially absorption peak at 227 nm. Results of IR- and UV-Vis spectroscopic analyses revealed that the interaction between levothyroxine and hydrogel occurs mainly due to hydrogen bonding and orientation forces of intermolecular interaction

The work is devoted to the electrochemical deposition of Bi-Se thin films from ethylene glycol-based electrolytes. The studies have been carried out by potentiodynamic and galvanostatic methods under various conditions, using Pt and Ni electrodes. By recording cyclic and linear polarization curves, the potential range of deposition of thin Bi-Se films on Pt (-0.75 to-1.2 V) and Ni (0.2 to-0.85 V) electrodes was determined. A comparison of the polarization curves of two electrodes showed that co-electrodeposition of Bi and Se occurs in approximately the same potential range. In order to find the optimal mode and composition of the electrolyte, the effect of various factors (concentration of initial components, temperature, etc.) on the process of co-electrodeposition of Bi with Se was studied. In addition, the samples of Bi-Se thin films obtained on Ni electrodes using the galvanostatic method were studied by scanning electron microscope (SEM) and X-ray phase analysis. The results of X-ray phase analysis confirmed the formation of thin Bi2Se3 films with and without additional heat treatment step. Elemental analysis of obtained films carried out by EDS shows that films contained 62.79 wt.% Bi and 37.21 wt.% Se.

Binary and complex chalcogenides with a tetradimite-like …
Binary and complex chalcogenides with a tetradimite-like layered structure are of great practical interest as topological insulators, thermoelectric, and optoelectronic materials. Their fundamental thermodynamic functions in combination with phase diagrams are important for the development and optimization of methods for the synthesis and growth of crystals. The work presents the results of a thermodynamic study of the starting compounds and solid solutions of the Bi2Se3-Bi2Te 3 system using the method of electromotive forces (EMF). Various modifications of this method are widely used to study binary and complex metal chalcogenides. Studies were carried out by EMF measurements of the concentration chains of the following type: (-) Bi (solid) | ionic liquid + Bi3+ | Bi in the alloy (solid) (+) in the temperature range 300-450 K. The pre-synthesized equilibrium Bi2Se3;tTex alloys (x = 0; 0.6; 1.2; 1.8; 2.0; 2.4; 3.0) with a 0.5 at% excess tellurium were used as right electrodes. Ionic liquid (morpholine formate) with the addition of BiCl3 was used as the electrolyte. The acquired experimental data were processed by the Microsoft Office Excel 2003 computer program using the least-squares method and linear equations of the type E = a + bT were obtained. The obtained equations of the EMF temperature dependences were used to calculate the relative partial molar functions of bismuth in the alloys. The diagram of solid-phase equilibria of the Bi-Se-Te system was used to determine the equations of potential-forming reactions and the latter were used to calculate the standard thermodynamic functions of the formation and standard entropies of Bi2Se3 …

The coordination compounds of Fe (II) and Fe (III) with phthalic acid were synthesized. The compounds were studied by X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and IR spectroscopy. It has been established that, regardless of the oxidative number of iron, the synthesis products have the same chemical composition and chemical formula-[Fe2 (oC 6H4 (COO) 2) 3]. It also found that the carboxyl groups of phthalate dianion have a monodentate and bridging function and the complex itself is a polymer-layered structure. Based on the obtained results, a schematic structure of the complex was proposed. Also were studied the thermal stability of the complex in the temperature range 20-660 С and the supramolecular interaction of this substance with the rheological properties of heavy commercial oils. This significantly reduces the viscosity of heavy oil during transportation. Coordination polymer-based composites have been developed and tested. The use of composite solves several technological problems associated with the transport of high-viscosity oil.

Activity of mordenite-zirconia catalysts in n-butane isomerization …
Activity of mordenite-zirconia catalysts in n-butane isomerization depends on the dealumination degree of H-mordenite, the concentration of zirconium dioxide, the preparation method of samples, the nature and the concentration of different promoters. The modification of dealuminated H-mordenite with ratio Si/Al=8.5 (HM8.5) by zirconyl nitrate, sulfate ions and cobalt results in a considerable increase in the catalyst activity and a decrease in the temperature of reaction. The influence of temperature, of carrier gas and of dilution of the feed stream has been studied on n-butane conversion and yields of main reaction products. In the temperature range of 473–513 K, the formation rates of isobutane, isopentane and propane increases with the pressure of n-butane. The influence of the pressure of hydrogen (PH2) on the reaction rates depends on temperature: at 473 K a negative order with respect to PH2 is observed …

A photovoltaic solar cell (PVSC) is a …
A photovoltaic solar cell (PVSC) is a type of power system that uses photovoltaic technology to convert the energy of solar light directly into electricity and is therefore capable of operating only when illuminated. Because the sun does not shine at all hours of the day in a given location, solar power is intermittent. Due to this intermittency, PVSCs are unable to provide electricity during the evening and night. For this reason, it is essential to hybridize the PVSCs with electrical energy storage (EES) devices such as capacitors, Li‐ion batteries, and supercapacitors (SC) in one single power unit. One of the most promising support systems for meeting the enormous and diverse power demand in contemporary civilization is sunlight‐powered energy conversion, which simultaneously achieves power conversion and energy storage. SCs can store huge amounts of energy and have a long service life. They also have a fast …

The dependence of the composition of Sb2S3 thin semiconducting films electrochemically deposited from an aqueous electrolyte containing SbOCl and Na2SO3 on the conditions of galvanostatic electrolysis was studied. With an increase in the SbOCl concentration and electrolysis time, the antimony content of the films obtained increases, whereas with an increase in the electrolyte temperature, current density, and Na2SO3 concentration the antimony content of the thin films decreases. The optimum electrolyte composition and electrochemical deposition conditions for preparing Sb2S3 thin films of the composition close to the stoichiometry were found.

The composite catalyst of 10% ZrO2, 0.4% Co, 2% SO42-/HZSM-5 designed for low-temperature conversion of straight-run gasoline (SRG) was synthesized. The influence of technological parameters (temperature, volumetric rate and ratio of hydrogen to initial raw material -H2/SRG) on catalytic and regeneration properties of the catalyst was investigated and optimal process conditions under which the conversion of C8+ is 76.8%, and the sum of hydrocarbons C5-C6 consisting of 78.8% of high-octane isomers, rises from 11.0% to 61.1.2%, were established. Regenerative characteristics of the catalyst were studied. The stability of the work of the samples and the amount of carbon compounds were determined depending on the duration of the reaction, the temperature of preliminary reduction of the samples by hydrogen, and the introduced hydrogenolysis metals (Co, Ni). It found that rise in the regeneration temperature of a 10% ZrO2,0.4% Co, 2% SO42-/HZSM-5 sample from 380 to 5000C leads to the stability of the catalyst. Replacing of Co with Ni enhances the stability of the catalyst due to the decrease in the rate of accumulation of carbon deposits; however, the selectivity of the catalyst is reduced.

The temperature dependence of the benzotriazole derivatives …
The temperature dependence of the benzotriazole derivatives chromatographic retention on hypecrosslinked polystyrene from water-acetonitrile eluent with different acetonitrile content was studied. It has been shown that the retention of benzotriazole derivatives on the surface of hypercrosslinked polystyrene is generally subject to the laws of the reversed-phase variant of HPLC. At the same time, the dispersion interactions of the heteroaromatic fragment with the sorbent surface make the main contribution to the chromatographic retention; however, the presence of functional groups of different chemical nature in the main heteroaromatic fragment leads to significant variations in the sorption characteristics, which are also determined by the composition of the eluent. From the experimentally determined thermodynamic characteristics of the sorption of benzotriazole derivatives, it follows that the change values of the standard molar enthalpy and Gibbs energy of sorption during the transition of the molecules of the studied analytes from the bulk solution to the surface layer of the HCPS are negative. This fact testifies to the exothermicity of the process and its spontaneous flow. The values of thermodynamic parameters of the studied derivatives vary in a relatively narrow range and are determined mainly by the nature of the substituent and its position in the heterocycle, remaining generally not as significant as the magnitude of the retention factor. Based on the analysis of the calculated enthalpy and Gibbs energy of sorption values, the influence of the functional groups nature on the studied substances retention was established, as well as differences …

Six-nuclear complexes of Platinum(II) with cleavage of a cystamine dihydrochloride by β-mercaptoethylamine with composition [Pt6(H2NCH2CH2S)8]Cl4·5H2O had been syntesized for the first time. Structure of the complex had been installed together with IKS- and XRD analysis. It has been established that each atom of platinum is surrounded by two atoms of sulfur and nitrogen due to bidentate coordination of a ligand. Only two of the six platinum atoms are on the same plane; other four atoms are in the different crossing planes. Four platinum atoms form adurable metal chelate cycles, which collapse over temperature 260℃. The results of IR spectroscopy confirmed with the RS-analysis.

An investigation has been made of the alkylation of phenol by methanol in the presence of CaY and NiCaY zeolites. The influence of temperature (300-380{degrees}C) and the volume feed rate of the feedstock (0{center_dot}5-1{center_dot}.4 hr{sup {minus}1}) on the yield and isomeric composition of the cresols formed has been established. The introduction of 1{center_dot}5 wt.% nickel into CaY increases the selectivity of o-methylation of phenol and the stability of operation of the catalyst. it can be assumed that CaY is more active in isomerization than NiCaY. An increase in temperature from 340 to 380{degrees}C and a decrease in the volume feed rate of the feedstock from 1{center_dot}4 to 0{center_dot}5 hr{sup {minus}1} promote an increase in the amount of m- and p-isomers, which is evidently due to subsequent isomerization of o-cresol on acid centres of CaY. It has been established that, at a temperature of 380{degrees}C, the m-isomer content in the cresol fraction reaches 25%. 6 refs., 1 fig., 1 tab.

В отличие от многих других модификаций цеолитов типа Х и У катализаторы NiNaY активны не только в алкилировании ароматических углево-дородов олефинами [1], но и в димеризации этилена [2, 3]. Реакция бензо-ла с этиленом на этих катализаторах идет с образованием вторичного бу-тилбензола (ВББ)[4]. Доказано непосредственное участие катионов Ni2+ в катализе синтеза ВББ из С6Н6 и С2Н4 [4, 5]. В цеолитах типа Ү эти катио-ны выполняют две функции: создают активные центры димеризации С2Н4 и разлагая молекулы Н2О, генерируют протоны, формирующие кислотные центры, ответственные за алкилирующую активность. В связи с этим очевидно значение для активности и селективности Ni-форм цеолитов количества, местоположения, состояния Ni2+(координация по отношению к атомам кислорода каркаса и степень «гидролизованности»), а также их доступности для адсорбируемых молекул. Эти факторы, влияющие и на кислотные свойства образцов, зависят от структуры и состава цеолитов (отношение SiO2/Al2O3, степень обмена Na+ на Ni2+, наличие катионов других металлов-М²+), а также условий их обработки. свойств

Boehmite samples with compounds of the composition …
Boehmite samples with compounds of the composition (C 5 H 5) 2 FeMnX 2 (μ-CO) n, where X= Cl, Br and n= 1.2, precipitated at room temperature from tetrahydrofuran solutions and then heated in an air flow up to 873 K were obtained and characterized using X-ray diffractometry, infrared Fourier spectroscopy, electron magnetic resonance and temperature-programmed desorption methods. It was shown that the thermal decomposition of these compounds applied to the boehmite samples in the range from room temperature to 873 K occurs stepwise and consists of at least two stages. The first stage of thermal decomposition occurs in the range of 453–753 K, and the second–in the range of 813–843 K. The XRD data show that when calcining at 873 K the boehmite samples with the applied compounds of the above composition and containing these compounds less than 10 wt.%, the diffraction patterns show only reflections characteristic of poorly crystallized aluminum oxide. However, the electron paramagnetic resonance (EPR) spectra of these samples clearly show intense signals characteristic of superpara/ferromagnetic particles of iron and manganese oxides, as well as EPR signals from isolated Fe 3+ substituting Al 3+ ions in the aluminum oxide structure. EPR spectra most of the iron and manganese is stabilized on the surface of poorly crystallized aluminum oxide in the form of nanostructured iron and manganese oxides.

Based on the study of current-voltage dependences during the co-deposition nt electrical reduction of rhenium and molybdenum from sulfuric acid on a Pt electrode, conditions for deposition of alloy nanocoatings of the Re-Mo system were established. The influence of various factors, such as the content of components in the electrolyte, current density, temperature, acidity of solutions, etc., on the composition and quality of coatings was studied. It was established that with an increase in the content of rhenium in the electrolyte and increase of current density, the content of rhenium in the alloy is increased. The composition and morphology of Re-Mo thin films electrodeposited on a platinum electrode were analyzed. The phase composition of the obtained films was determined by XRD using a diffractometer, and the study of the morphology of Re-Mo films on platinum and nickel substrates was performed using a scanning electron microscope. Based on this study, the optimal conditions for the deposition molybdenum with rhenium and the required composition of the electrolyte were selected. For the obtaining rhenium-molybdenum alloys containing 50-80 wt.% Re, the following electrolyte composition can be recommended: 0.0015 M Na2MoO4+ 0.0035 M KReO4+ 2M H2SO4, pH 0.4; t= 75 C, electrode-Pt.

An analysis is made of kinetically and aggregatively unstable non-Newtonian oil disperse systems and of the reasons for the occurrence of this instability that are associated with the coalescence of droplets and their settlement. In this connection, the authors have proposed models of thinning and rupture of the interphase non-Newtonian film between two joined droplets, and also the model of change in the thickness of the interphase film. The Ostwald–de Waele model satisfactorily describing pseudoplastic properties of oil was taken as the basis for the investigation. A model of settlement of particles in a non-Newtonian oil was proposed. The proposed models were compared with the existing experimental data, which has shown their efficiency. Consideration has been given to the conditions of self-organization of aggregatively and kinetically unstable disperse systems. It has been noted that such systems, in the …

Based on the study of current-voltage dependencies during electroreduction of molybdenum ions from sulfate electrolytes on Pt electrode, the conditions of deposition of Mo-nanocoatings were established. The influence of various factors such as temperature, content of components in the electrolyte, current density, acidity of solutions, etc., on the composition and quality of coatings was studied. It was found that, with an increase in the concentration of molybdenum and current density, the molybdenum content increases and the quality of coatings improves. Based on the determination of the nature of the cathodic polarization, it was found that the process of electrodeposition of molybdenum from sulfate electrolyte is mainly accompanied by chemical polarization. According to the experimental data, the following electrolyte composition (mol/l) is recommended for obtaining molybdenum nanocoatings: 2.0·10ˉ²– 1.5·10ˉ³ Na2MoО4 +2.0 H2SO4; pH=0.4; EV=0,005 Vsˉ¹; t=75ºC, electrod – Pt.

The problems of heavy oil rheology, accompanied by physical phenomena of the formation and destruction of coagulation disordered structures and aggregates as a result of the hydrodynamic interaction of particles (asphaltenes, paraffins, resins, and solid-phase particles) contained in the oil, which significantly affect its properties and flow, are considered and analyzed. Rheological models of viscous-plastic heavy oils are considered and developed, consistent with a variety of experimental data. New rheological models for viscous-plastic heavy oils are proposed, which make it possible to generalize many existing models. It is noted that the variety of rheological models for heavy oils is determined by the conditions for the formation of disordered structures in the bulk of the oil flow. For heavy oils, a nonlinear equation for filtration in porous media is proposed, depending on the shear stress, pressure gradient, effective viscosity of the oil, and a number of other parameters. An analytical solution to this equation is proposed, which is consistent with the experimental data. Models for the settling rate and drag coefficient of particles in heavy oils are proposed. Applied problems of rheology aimed at improving the rheological properties of heavy oil during their processing as a result of creating a recirculation scheme at an operating oil refining unit are considered.

The platinum nanocomposites with mesoporous carbon nitride …
The platinum nanocomposites with mesoporous carbon nitride (Pt/mpg-C3N4) were synthesized by in situ reduction of H2PtCl6·6H2O with aqueous methanol and studied as catalysts in phenylacetylene hydrogenation in the gas phase at 150 °C and atmospheric pressure in the flow process. The efficiency of hydrogenation can be enhanced by using available organic modifiers. The addition of pyridine, piperidine, or morpholine to the starting solution of phenylacetylene in hexane provides 95–100% conversion and 90–92% selectivity to styrene on the Pt/mpg-C3N4 catalyst. A sharp increase in the selectivity to styrene without substantial changes in conversion is observed when THF, ethanol, triethylamine, dioxane, or chloroform are used as diluents. No loss of activity or selectivity was observed during 10-h tests of the catalyst in the flow process.

Теоретические исследования процессов очистки нефтяных сточных вод …
Теоретические исследования процессов очистки нефтяных сточных вод от различных примесей позволили установить основной механизм, связанный с образованием коагуляционных структур и агрегатов с последующим их осаждением и расслоением, приводящим к нарушению агрегатной и кинетической устойчивости среды. Обнаружено, что более глубокий процесс коагуляции приводит к разрушению прослоек среды между частицами и их непосредственному контакту, в результате чего образуются жесткие агрегаты фрактальной структуры из твердых частиц и асфальто-смолистых веществ, иногда в виде хлопьев в сточной воде. В результате коагуляции частиц в турбулентном потоке их число уменьшается, хотя размеры растут вплоть до размеров агрегатов. Отмечено, что образование коагуляционных структур является положительным фактором для разделения и расслоения твердой фазы от жидкой с целью очистки сточных вод. Изучены возможности использования синергетической смеси (гашеная известь и хлорное железо) с целью ускорения образования коагуляционных структур для очистки нефтяных сточных вод. Экспериментальные исследования показали эффективность использования такой смеси для очистки сточных вод от нефтепродуктов и частиц твердой фазы. При интенсивном перемешивани этой смеси в мешалке с частотой вращения 1500–2000 мин–1 достигается изотропная турбулентность, которая положительно влияет на коагуляцию и агрегирование частиц. Выявлено, что наиболее приемлемые количества гашеной …

In order to reduce the side effects of thyroid hormone substitute levothyroxine sodium pentahydrate, its sorption with a quaternized salt of a new alkyl derivative of chitosan was studied. The drug amount in the salt (gel) is in micrograms, and the gel - levothyroxine is in the form of a complex that can show biological activity. With that end in view, a sorption process of levothyroxine sodium from an aqueous solution to the inside and surface of the hydrogel was carried out under static conditions. The capacity of the hydrogel depending upon the pH medium, the ionic strength, the hydrogel dose, the concentration of the drug and the temperature was studied. It was shown that the effective sorption of levothyroxine by chitosanbased hydrogel was optimal at pH of 6 - 8.5, at 50 mg/L concentration of levothyroxine in the presence of 10 - 50 mg of hydrogel dose but the sorption degree begins to decrease after T=40 °C. The isotherm results of sorption processes have been found to be subordinate mainly to Langmuir and to some extent Freundlich equations. It revealed that gel degradation in the oxidizing medium is about 70% within 2 weeks, and in the elastase and PBS medium is about 17 - 20%

The paper presents data on the study of the electrocatalytic properties of Ni-Mo thin films in neutral and alkaline media, obtained as a result of electrochemical synthesis. Comparative characteristics of the electrocatalytic properties of deposited Ni-Mo films on various substrates and different compositions with the catalytic activity of Ni, Pt and St-3 were determined by the method of recording linear polarization curves and determining the slope of the Tafel curves. The highest catalytic activity was exhibited by Ni73.5Mo13.3O13.2 thin films on a nickel substrate that were not annealed. The dependence of the microhardness of the films on their composition was determined, and Ni-Mo films with a Mo content of 38% had the highest microhardness. It has been established that the corrosion resistance of films depends on the content of molybdenum in them, and an increase in its content in alloys increases their corrosion resistance, but the catalytic activity of the films decreases

Thin n-type MoS2 films have been produced by electrochemical deposition from aqueous electrolytes and some of their electrical and photoelectrochemical properties have been studied using advanced characterization techniques (X-ray diffraction, scanning electron microscopy, and Raman spectroscopy). We have measured the current–voltage characteristics of the films and their electrical conductivity as a function of temperature and evaluated their temperature sensitivity coefficient (B = 16 376 K), the temperature coefficient of their electrical resistance (α = 0.182 K–1 at 400 K and 0.095 K–1 at 500 K), and their band gap (Eg = 1.41 eV). The results demonstrate that thin MoS2 films have attractive photoelectrochemical properties and can be used in solar energy conversion.

The phase equilibria in the ternary Tl–Se–I …
The phase equilibria in the ternary Tl–Se–I system have been investigated by means of differential thermal analysis, X-ray powder diffraction and the electromotive force measurements (EMF) of electrochemical cells relative to the thallium electrode with ionic liquid as an electrolyte. Several polythermal sections, the isothermal section at 300 K and the projection of the liquidus surface of the system have been constructed. The homogeneity and primary crystallization regions of intermediate phases, as well as types and coordinates of non- and monovariant equilibria have been determined. Formation of two congruently melting ternary compounds (Tl5Se2I at 720 K, and Tl6SeI4 at 705 K) was observed. It was revealed that the system is characterized by the existence of wide areas of α- (based on Tl2Se) and δ-solid solutions (based on Tl5Se2I). Standard thermodynamic functions of formation and standard entropies of …

Исследована температурная зависимость хроматографического удерживания производных бензотриазола на сверхсшитом полистироле из водноацетонитрильного элюента с различным содержанием ацетонитрила. Показано, что удерживание производных бензотриазола на поверхности сверхсшитого полистирола в целом подчиняется закономерностям обращенно-фазового варианта ВЭЖХ. При этом основной вклад в хроматографическое удерживание вносят дисперсионные взаимодействия гетероароматического фрагмента с поверхностью сорбента, однако присутствие функциональных групп различной химической природы в основном гетероароматическом фрагменте приводят к значительным вариациям сорбционных характеристик, определяемым также составом элюента.

Очистка сточных вод от асфальтосмолистых веществ является …
Очистка сточных вод от асфальтосмолистых веществ является важной экологической и экономической проблемой, в связи с чем выбор метода реализации процессов разделения нефтяных эмульсий и очистки сточных вод является важной проблемой современного производства. Их решение связано с выбором типа растворителя, метода и характерного процесса утилизации, включающего процессы адсорбции и абсорбции, экстракции, использование мембранной и плазмохимической технологий [1]. Асфальтены в нефти–это твердые частицы размером 1, 0… 1, 5 нм, которые при определенной концентрации, в результате коагуляции и агломерации, образуют наноагрегаты, кластеры наноагрегатов и вязкоупругий каркас, придающий нефти определенные реологические свойства, характеризующие неньютоновские жидкости [2, 3].Экспериментальные исследования показали, что асфальтены очень хорошо растворяются в ароматических углеводородах, это и положено в основу разработки технологии очистки сточных нефтяных вод от нефтепродуктов. Следует отметить, что в сточных нефтяных водах после удаления асфальтосмолистых веществ в объеме потока остается во взвешенном состоянии большое количество тонкодисперсной твердой фазы (глина, песок, частицы минеральных солей и так далее), которая свободно не осаждается. Таким образом, второй проблемой после экстракционной очистки от асфальтосмолистых веществ является разделение взвешенной твердой фазы с использованием коагулянтов.

Thermodesorption of ethyl benzene from different cation and decationized zeolite forms of NaX and NaY types including BeY, NdY, CeY has been investigated by the chromatography method. The thermodesorption spectrum of all the specimens investigated consists of a single peak. Na cation exchange for polyvalent cations results in shifting temperature of thermodesorption type maximum to the low-temperature region. Calculated are diffusion activation energy, pre-exponential factors, effective diffusion coefficients. Dependences of the reaction rate of oxidizing dehydrogenation of ethyl benzene, effective diffusion coefficient on the value of electrostatic cation potential in the Y zeolite go through the NdY maximum

Given that substances containing an imine or azomethine fragment are included in the group of physiologically active substances, the synthesis of new Schiff bases or the development of new synthesis methods for existing ones is of interest. Two Schiff bases were synthesized by the photoorganocatalytic method and characterized by elemental analysis, UV–Vis, IR spectroscopy and X-ray single-crystal analysis. The reactions were carried out under light irradiation (household lamps 2 × 15 W) with stirring at room temperature without heating, resulting in yields of 83 and 80 %, respectively for I and II. To obtain the target product, aromatic aldehydes 5-bromosalicylic aldehyde and ortho-vanillin, as well as 2-amino-5-methylpyridine, derivatives of pyridine, representatives of heterocyclic amines, were used. Compounds were prepared by the aldol condensation. Cognitive impairment, known as dementia is typically …

| Immobilization and in vitro kinetic controlled release study of doxorubicin from temperature-sensitive mPEG-Ala-Asp polypeptide hydrogel | SOCAR Proceedings səh: 1-8 | DB Taghiyev, Sh Z Tapdiqov | 1 | 2024 |
The loading of the doxorubicin drug into …
The loading of the doxorubicin drug into a new polyethylene glycol-polypeptide based temperature-sensitive hydrogel and the investigation of its properties have been carried out. It was determined that during the immobilization of the drug, equilibrium is reached, and saturation occurs within 3 hours in a solution with an initial antibiotic concentration of approximately 4.8 mg/mL. Currently, 84-87% of the drug is adsorbed, meaning that 100 mg of gel drug capacity was 405.8 mg/gr. The samples were kept in different pH solutions (pH= 2, 7.4, and 8.6) at 37 C, and the release of doxorubicin was kinetically studied over intervals ranging from 0-300 minutes. It was determined that changes in the ionic strength of the solution lead to a change in the polarity degree of the chemical bond between the hydrogel and doxorubicin. The results of doxorubicin release from the gel were tested against various kinetic models, including zero-order, first-order, Higuchi square root law, Korsmeyer-Peppas, and Hixson-Crowell square root models. When applying the kinetic results of doxorubicin release from the gel to the Korsmeyer-Peppas model, in acidic and neutral mediums, the value of n> 1, which is attributed to the breaking of protein segments in the terminal groups of the matrix. This makes the creation of thin-coated drug formulations from the matrix more advantageous. In an alkaline medium, however, n< 1, indicating that the release follows a non-Fickian mechanism, characterized by both diffusion and erosion. To ensure release in an alkaline medium, it is more appropriate to prepare cylindrical, spherical, or film-type drug forms from the PEG-Ala-Asp gel …

This work presents studies to study the nucleation and growth mechanism of electrochemical NiMo films suitable for the decomposition reaction of water as an electrocatalyst, in which the value of the potential established from polarization measurements was maintained constant. Optimal conditions for the electrochemical synthesis of the Ni-Mo alloy on the surface of platinum and nickel electrodes were established using voltammetric studies examining the influence of many electrolysis parameters on the process of co-deposition of nickel with molybdenum. The chronoamperometric method provides more detailed information about the electrodeposition process by studying the nucleation and growth mechanism of electrochemical films in which the potential value determined from polarization measurements was kept constant. The curves were taken at various potential values -0.1, -0.2, -0.3, -0.4, -0.5, -0.6, -0.7, -0.8 and -0.9 V at room temperature. The study of these curves can be carried out by comparing the experimental calculated data with the equations of the Scharifker-Hills model. It was found that in the early stage, at potentials of -0.1 and -0.2 V, the experimental data fit into the curve of the progressive nucleation model, according to which Ni-Mo nucleation occurs on many active areas of the substrate surface, but at other potentials (from -0.3 to -0.9 V) deposition deviates towards instantaneous nucleation and growth

Results of the study of CO2 methanation on Co-containing catalysts based on Siral aluminosilicates with different SiO2/Al2O3 ratios (1, 10, and 40) are presented. It is shown that methane is the main product at temperatures up to 573 K, its yield varies depending on the SiO2/Al2O3 ratio of aluminosilicate. Carbon monoxide is formed along with methane at temperatures above 573 K. Maximum methane yields of 55% and 41% (at 573 K) are achieved on Co/Siral-1 and Co/Siral-10 catalysts. It is shown that catalysts reduced in a hydrogen flow are characterized by the presence of superpara/ferromagnetic particles and magnetic resonance parameters of their EMR spectra significantly depends on the SiO2/Al2O3 ratio of the aluminosilicate. It is assumed that the superpara/ferromagnetic particles formed during high-temperature hydrogen treatment of Co-containing aluminosilicates are catalytically active particles in …

Samples of MnOx-Na2WO4/SiO2 based on a mesoporous …
Samples of MnOx-Na2WO4/SiO2 based on a mesoporous silica matrix were synthesized using manganese acetate, sodium tungstate, tetraethoxysilane (TEOS) as precursors and cetyltrimethylammonium bromide (CTAB), citric acid and triethanolamine as pore generating agent and characterized by scanning electron microscopy with energy dispersive elemental analysis (SEM/EDS), X-ray diffractometry (XRD), electron magnetic resonance (EMR), N2 adsorption-desorption measurements and tested as a catalyst for the reaction of oxidative condensation of methane (OCM). It is shown that the MnNaW/SiO2 catalyst consists of Mn2O3, MnO2, Na2WO4 and SiO2 phases. The EMR and SEM/EDS data indicate a noticeable effect of the reaction conditions on the surface structure and the distribution of catalytically active components in the catalyst structure. Significant changes in the values of the specific surface area and pore volume of the samples with increasing temperature and duration of the reaction were found (the values of the specific surface area and pore volume, respectively, 116.8 m2/g and 0.590 cm3/g-up to and 46.1 m2/g and 0.232 cm3/g after 15 hours of catalyst operation in the OCM reaction at 800 C). It has been shown that under the conditions of the OCM reaction, the elemental composition of the surface of the MnOx-Na2WO4/SiO2 catalyst changes, and the degree of change depends on the duration of the OCM reaction. Under the influence of the reaction mixture CH4/O2, the content of Mn and W decreases in the first two hours, and the trend towards a decrease in their amount on the catalyst surface with an increase in the …

The platinum nanocomposites were synthesized by chemical reduction of H2PtCl6·6H2O in situ with a methanol—water mixture using mesoporous graphitic carbon nitride as a stabilizing matrix and a catalyst support. The textural, morphological, and optical properties of the obtained platinum – mesoporous carbon nitride composites (Pt/mpg-C3N4) were studied. Pt/mpg-C3N4 has been developed as an effective heterogeneous catalyst for the gas and liquid phase hydrogenation of phenylacetylene. An efficient and versatile approach to the modification of platinum with various organic solvents and ligands for the selective hydrogenation of phenylacetylene to styrene in a flow gas-phase process is presented. The addition of pyridine, piperidine, or morpholine to the starting solution of phenylacetylene in hexane provides 95–100% conversion and 90–92% selectivity to styrene. A sharp increase in the selectivity to styrene without substantial changes in conversion is also observed when THF, ethanol, triethylamine, dioxane, or chloroform are used as diluents. The obtained Pt/mpg-C3N4 composites also demonstrated considerable catalytic activity in the selective hydrogenation of phenylacetylene to styrene at low temperatures in the liquid phase.

Dehydrogenation of isobutane in the presence of oxygen has been studied over alumina supported vanadium (V/Al) and vanadium-antimony (VSb/Al) oxide catalysts. Their catalytic behaviors at 550 C were compared with the sample characterization data obtained by several physico-chemical methods: BET specific surface area, X-ray diffraction, X-ray photoelectron spectroscopy, hydrogen temperature-programmed reduction, temperature programmed desorption of oxygen, in situ DRIFTS (diffuse reflectance-absorption infrared Fourier transform spectroscopy), and in situ DSC (differential scanning calorimeter) methods. VSb/Al catalyst exhibited, at high catalytic activity, the enhanced on-stream stability compared to V/Al oxide. In the presence of modifier, antimony oxide, the amount of active mobile oxygen species and their reactivity in redox transformations is improved. As a result, VSb/Al oxide displays highcatalytic activity together with lower coking activity and higher on-stream stability.

Redox systems MenFc/MenFc+ (n=6, 8, 10) consisting of symmetric polymethylferrocene and the corresponding polymethylferricinium cation have been studied by cyclic voltammetry in organic solvents - acetonitrile, dichloromethane and dimethylsulfoxide. The values of the diffusion coefficient of the reagents (MenFc and MenFc+) of redox systems have been calculated by the Randles-Sevcik equation, which are consistent with the conclusion that "a one-electron reversible electrochemical reaction is determined by the diffusion of the reagents". The features of the change in the values of the diffusion coefficient, both in the sequence of Fc/Fc+→Me6Fc/Me6Fc+→ Me8Fc/Me8Fc+ → Me10Fc/Me10Fc+ redox systems and in dependence on the presence or absence of the charge in the reagents, have been interpreted by the change in the volume (dimensions) of the reagents with increasing number of methyl groups and the interaction of polymethylferricinium cations with electrolyte anions in solution.The fact that the diffusion coefficient of the cation in each MenFc/MenFc+ redox system is very close to the diffusion coefficient of the molecule, which allows us to replace the standard electrode potential (Eo) of the system with the half-wave potential (E1/2) according to the Nernst equation. The effect of the nature of the solvent on the value of the half-wave potential of these redox systems has been studied. It has been shown that the appearance of methyl groups in cyclopentadienyl rings significantly weakens the interaction of reagents (especially the iron atom) with solvent molecules, in comparison with the interaction in the Fc/Fc+ system and, as a result …

The rheology problems of non-Newtonian oil, accompanied by the physical phenomena of formation and destruction of coagulation structures and aggregates, significantly affecting the flow are considered and analyzed. Also are considered issues of hydrodynamic interaction of particles leading to the formation of disordered structures, which significantly change the rheological properties of non-Newtonian oil. It has been noted that the formation of coagulation structures depends on energy dissipation, viscosity, stress or shear rate, and the size of the particles forming the structure. With increasing asphalt-resin content in the oil, the probability of particle collision increases, increasing the rate of formation of various disordered structures up to a framework that nullifies the rate of oil flow. Applied problems of rheology, including dissolution kinetics of asphalt-resinous substances in aromatic hydrocarbons and improving rheological properties of the oil, rheology of structured non-Newtonian oils in gas lift method of production, as well as possible ways to create new technologies for processing non-Newtonian oils were considered.

The results of testing well-known MnNaW and LaCe catalysts based on SiO2 in the oxidative conversion of methane (OCM) to obtain a C2+ COx mixture with a certain C2H4/CO ratio for hydroformylation to propylene, morphology and the studies of phase composition, distribution of active elements in the catalyst structure, magnetic, optical, textural properties are presented. The results of research within the framework of the Horizon2020 project showed that MnNaW catalysts based on SiO2 MnNaW catalysts are noticeably superior in catalytic characteristics to LaCe catalysts, although the texture characteristics of LaCe catalysts are comparable to MnNaW catalysts. All three catalysts are mesoporous. Among these three porous samples, the sample with the ratio Si/(0.9 La+ 0.1 Ce)= 50 has the highest porosity and surface area. The MnNaW and LaCe samples with Si/(0.9 La+ 0.1 Ce)= 10 have almost the same surface area, but the pore volume in the MnNaW catalyst is 2 times larger than in the LaCe catalyst with Si/(0.9 La+ 0.1 Ce)= 10, due to the larger pore size. In addition, the average pore diameter in these three samples is in the range of 2-50 nm, so they can be attributed to mesoporous materials.For catalysts with the composition NaMnW/SiO2 prepared using CTAB and TEA surfactants, methane conversion up to 47.7%, selectivity for C2 and C3 hydrocarbons in total up to 86.7% and yield up to 27.4% were observed. Under identical conditions, these catalysts were found to be more active than lanthanum-cerium catalysts. An increase in temperature from 778 to 874 C leads to an increase in the selectivity for ethylene and the yield of C2+ C3 …

Рассматриваются проблемы, связанные с кристаллизацией и отложением парафина и асфальто-смолистых веществ из нефти в транспортных трубах. Отмечено, что осаждение частиц парафина носит миграционно-диффузионный характер. Предложены миграционно-диффузионный механизм и кинетика кристаллизации парафинов и их отложения в транспортных трубах и в трубах теплообменных аппаратов. В результате решения уравнения переноса тепла построена модель распределения температуры в трубах с отложением. Сравнение моделей с имеющимися экспериментальными данными дало удовлетворительные результаты.

The trinuclear complexes with simple and mixed ligands of palladium (II) with mercaptoethanol and mercaptoethylamine have been generated and their contents and structures investigated by numerous physicochemical methods. Mercaptoethanol (HSCH2CH2OH) is coordinated monodentally with just sulfur atom and forms pentacyclic metalchelate ring, where as mercaptoethylamine (HSCH2CH2NH2) is coordinated monodentally as well as bidentally and forms identical ring (pentacyclic metalchelate). The sulfur atom of ligands plays a bridge role between metals in the trinuclear palladium complexes. The hydroxyl group of mercaptoethanol does not participate in the coordination.

Kinetic regularities of the involvement of C7+ components of straight-run gasoline in the conjugated isomerization and disproportionation process for obtaining of highoctane isomeric components of C5-C6 on the composite Co-HZSM-SO4 2-/ZrO2 catalyst are established. A regression model of the process is created, activation energies are calculated. It was found that the limiting stage of the PSRG transformation is the primary isomerization of the C7+ components, proceeds more fovarabbly, which is facilitated by low activation energies. Proposed that the resulting model will be used to make the mechanism of the course of the main and adverse reactions

Изучены кинетические закономерности жидкофазного окисления циклогексанона в присутствии комплексов меди и кобальта со сшитыми полиэтилениминами и карбоксильной смолой. Установлено, что в присутствии комплекса меди со сшитым ПЭИ при 1400С скорость реакции увеличивается примерно на порядок. То же самое наблюдается в присутствии комплекса кобальта со сшитым ПЭИ. В случае использования в качестве носителя карбоксильной смолы КБ-4П2, каталитическая активность комплексов кобальта значительно выше комплексов, содержащих медь. Установлена оптимальная концентрация катализатора, увеличение которой приводит к ингибированию скорости реакции.

This article presents the study of the synthesis of the ternary Pb-Sb-Te alloy on the stainless steel substrate via electrochemical method. The corrosion resistance of the electrodeposited alloy has been investigated via subjecting the electro-synthesized alloy to a corrosive medium containing sulfide ions; this medium is similar to the petroleum refining environment. The resulting film of the electrodeposited alloy was analyzed by the scanning electron microscope, energy-dispersive X-ray analysis, and X-ray diffraction to determine the morphology and the phase structure of the electrodeposited film. It was found that the electrodeposited Pb-Sb-Te alloy thin film is a multiphase composition. The obtained data reveal that the most corrosion-resistant phase is the PbSb2Te4 alloy.

Change of electroresistance of thin coatings of rhenium chalcogenides depending on temperature has been investigated. It is established that with a rise in temperature the specific resistance decreases, ie semiconducting course of conductivity takes place. On curves of dependences on logarithms of the specific resistance and specific electro conductivity there are two linear sections which meet the different values of energy activation. It is shown that with a rise in temperature the transition from admixtured electro conductivity to one’s own occurs. The width of the prohibited zone in a field of own and admixtured conductivity has been calculated.

Проанализированы и обобщены особенности образования имидного гетероцикла из субстрата и другого основного продукта – динитрила при окислительном аммонолизе о-ксилола, а также 4броми 4-фенил-о-ксилолов. Обнаружено, что в обоих случаях образование имидного цикла происходит за счет пространственного эффекта, связанного с расположением боковых орто-групп на наиболее близком расстоянии друг от друга, способствующем их внутримолекулярному взаимодействию. Выяснено, что эффект пространственного содействия орто-метильных заместителей субстрата и орто-нитрильных функциональных групп динитрила связан с окислительной циклизацией соответственно в условиях окислительного аммонолиза и под влиянием воды, являющейся продуктом сопутствующих реакций окислительного дегидрирования и глубокого окисления.

This study presents the research results on the co-deposition of nickel and cobalt from an alkaline electrolyte containing glycine. For this purpose, cyclic and linear polarization curves of co-deposition were obtained at various cobalt concentrations, different poten-tial sweep rates, and electrolyte temperatures. It was established that the co-deposition process occurs anomalously, with the cobalt content in the deposited films exceeding that of nickel. The deposits obtained under optimal conditions contained 37.25% Ni and 51.43% Co. The study of the effect of the potential sweep rate on the co-deposition process of nickel and cobalt revealed a linear relationship between the current peak value and the square root of the potential sweep rate. This indicates that the initial stage of Ni-Co co-deposition is controlled by the diffusion of the metal ions to the cathode surface. When recording polarization curves on a rotating disk electrode at different rotation speeds, the relationship between the current peak value and the square root of the electrode rotation speed was also linear at relatively low rotation speeds. However, at higher rotation speeds, the process was controlled by electrochemical polarization. The co-deposition of Ni with Co was confirmed through X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectroscopy analyses. The investigation of the catalytic activity of Ni-Co deposits in a neutral medium (0.5 M Na₂SO₄) demonstrated that the amorphous thin films, not subjected to annealing, exhibited the best electrocatalytic properties for the hydrogen evolution reaction. The Tafel slope was determined to be 118 mV …

Through a new two-pyrazine-modulated oligo-α-pyridylamino ligand, N2,N2′-(pyridine-2,6-diyl)bis(N6-(pyrazin-2-yl)pyridine-2,6-diamine) (H4N9-2pz) (1), the highest nuclearity linear nonachromium(II) metal string complex [Cr9(µ9-N9-2pz)4Cl2] (2) was successfully synthesized and structurally characterized. According to X-ray crystallographic studies, the complex 2 showed a localized unsymmetrical structure consisting of four quadruple Cr–Cr bonds and one single high-spin Cr(II) at the end of the molecule. The four deprotonated supporting ligands are helically wrapped around the metal score. Temperature-dependent magnetic study revealed a quintet ground state resulting from the isolated, high-spin Cr(II) atom.

The replacement of noble metal-based catalytic systems with oxide catalysts based on transition metals of variable valency for the oxidation of carbon monoxide, the reduction of catalyst production costs, and simultaneously the reduction of energy costs for carrying out the reaction is a pressing issue. In this work, binary copper ferrites and ternary copper-manganese-iron oxide systems were synthesized for lowtemperature carbon monoxide oxidation using the sol-gel method with self-combustion, as well as using microwave technology. The samples were characterized using X-ray diffraction technique, infrared spectroscopy, and thermogravimetric differential thermal analysis methods, their specific surface area was measured by the BET method, and microphotographs were taken using a scanning electron microscope. The adsorption of carbon monoxide on catalysts has also been studied. It has been found that the resulting binary and ternary copper-containing oxide systems are multiphase systems containing ferrites, manganites, and oxides of copper, manganese and iron. The resulting catalysts are active in the low-temperature carbon monoxide oxidation in the temperature range of 145-180ºC. In the systems, an enhancing effect of the influence of its components oxide and spinel (ferrite) phases on the catalytic activity is observed. Due to thermal desorption data, for the studied catalysts on which the oxidation of carbon monoxide occurs at sufficiently low temperatures, carbon monoxide adsorption is observed approximately in the same range. The appearance of various structural defects during short-term combustion of the gel without …

Comparison of the structural parameters of the monosubstituted complex (tBuCp)2Mo2(CO)6 (1) with the corresponding structural parameters of the disubstituted (1,2-tBu2Cp)2Mo2(CO)6 (3) and unsubstituted Cp2Mo2(CO)6 (2) complexes allowed us to identify the features of the crystal structure (3) caused by the presence of two tert-butyl substituents in the 1,2(vicinal) position in the cyclopentadienyl (Cp) ring. These features are manifested primarily in the change in the length of the Mo–Mo bond, the magnitude of the rotation angle of both the tBu2Cp ring around the Ct–Mo axis and the tert-butyl groups around the C(ring)–C(tBu) bond, the length of the C–C bonds in both in the cyclopentadienyl C5-ring and the tert-butyl substituent, and the values of the internal and external C–C–C angles of the cyclopentadienyl C5ring. Most of these features are due to steric interactions observed in the crystal structure (3) between different groups and fragments of the molecule.

Studies have shown that gentamicin-impregnated collagen can significantly reduce infection rates in surgical sites, as demonstrated in vascular surgery and abdominal procedures. While gentamicin-collagen systems have shown promising results, challenges remain regarding their long-term stability, biodegradation, and in vivo efficacy. Future research should focus on optimizing the formulations, ensuring biocompatibility, and exploring their potential in advanced drug delivery and tissue engineering applications. Overall, the integration of gentamicin with collagen represents a significant advancement in biomedical materials, offering effective solutions for infection control and tissue repair. The synergistic utilization of collagen-based carriers and advanced vesicular systems, such as transferosomes, represents a promising strategy to overcome limitations associated with systemic antibiotic therapies [3]. By providing localized, sustained, and targeted drug delivery, these systems offer safer and more efficacious alternatives for infection management, particularly in surgery and postoperative care [4]. Future research should prioritize the optimization of these delivery platforms to ensure translational success in clinical practice, addressing current challenges in infection prophylaxis and treatment. Complex drugs with specific properties are created by immobilizing various drugs (anticoagulants, glycosaminoglycans, antiseptics, antibiotics, enzymes, antioxidants, regeneration and osteogenesis stimulants, etc.) on collagen. In this regard, research work devoted to the synthesis of the collagen-gentamicin complex and the study of its biological activity is …

The conversion of C 6 H 6: …
The conversion of C 6 H 6: C 3 H 8 mixtures on a mechanical catalyst mixture (MC) consisting of HY, HM or HZSM-5 zeolite and M, Re/Al 2 O 3 was studied. As a result of propane activation in the presence of benzene on the catalytic system, the components of the benzene-propane mixture at low temperatures (473-673 K) are converted into alkylaromatic hydrocarbons C 9 and propene. It was found that propane dehydrogenation to propylene occurs already at 523 K with benzene as a stoichiometric reaction component. Based on the obtained data on the dependence of the yield of propylene and isopropylbenzene on the experimental conditions, an assumption was made about a common intermediate compound preceding the formation of these products. Thermodynamically unfavorable reactions of benzene dehydroalkylation with propane and the process of propane dehydrogenation are explained by the occurrence of conjugate oxidation-reduction interaction due to cyclic proton transfer between the zeolite and partially reduced centers of the metal component of the MC and alternating oxidation and reduction of these centers. As a result of the studies, the effect of benzene on the low-temperature activation of propane on mixed catalysts consisting of a mixture of (50 x 50) M, Re/Al 2 O 3+ H-zeolite, leading to the formation of isopropylbenzene, propylene and C 9-alkylaromatic hydrocarbons, was established; the dependence of the yield of the conversion products of the C 6 H 6: C 3 H 8 mixture on the reaction conditions and the nature of the zeolite component of the mixed catalyst was established.

Composite catalysts for the oxidative dehydrogenation of …
Composite catalysts for the oxidative dehydrogenation of ethylbenzene to styrene were synthesized based on zirconium, magnesium and aluminum oxide. Under the reaction conditions of WHSV=0.5h-1, EB : air = 1:6 or EB : CO2 = 1:5, 480oC, in the presence of O2, the conversion of EB and selectivity of St on 1%ZrO2,2.0%MgO/Al2O3 +5% P2O5 catalyst reaches 62 and 90%, and in the presence of CO2, these indicators reach 54 and 94%, respectively. The inclusion of copper in the synthesized catalysts increases their activity and selectivity. The conversion of EB in the presence of CO2 over 1%ZrO2,2.0%MgO/Al2O3+5%P2O5+1% CuO under reaction conditions of WHSV =1h-1, GHSV =500h-1, 500oC is 62% and St selectivity is 96%. The inclusion of copper in the composition of the synthesized catalysts allows the conjugation of the dehydrogenation of EB to St with the steam conversion of carbon monoxide. The conjugation of these reactions increases the conversion of EB to St. In this case, under the reaction conditions of 500oC, WHSV=0.5h-1, GSHV = 500h-1, the conversion of EB is 65%, the St selectivity is 92 % on 1.0%ZrO2,2.0%MgO/Al2O3+5%P2O5+1%CuO catalyst. It was determined that the conjugation of the dehydrogenation of EB to St with the steam conversion of carbon monoxide allows to create a simultaneous and environmentally harmless process of obtaining styrene and hydrogen.

For the oxidative dehydrogenation of ethylbenzene into styrene, a composite catalyst based on copper (II) oxide, which carries out steam conversion of carbon monoxide, and an aluminothermic catalyst, which is a catalyst for the dehydrogenation of hydrocarbons, have been synthesised. Oxidative dehydrogenation of ethylbenzene to styrene was carried out on this catalyst in the presence of air oxygen and carbon dioxide. It was found that although the conversion of benzene during oxidative dehydrogenation in the presence of oxygen is high, the selectivity for styrene is low, in which case benzene, toluene, methane, ethane, CO and CO2 are formed more. The process itself requires strict control as the oxygen: hydrogen mixture is dangerous. When the process is carried out in the presence of CO2, although the conversion of ethylbenzene is relatively low, the selectivity for styrene is high and the yield of by-products …

The products obtained as a result of the simultaneous reaction of chitosan, a Schiff-based natural polyaminosaccharide, with formaldehyde and benzaldehyde were synthesized by the method indicated in the experimental part of the article. The two amine groups formed were then reduced with NaBH4 to give the corresponding tertiary amine derivative. The structure of the obtained product was characterized by scanning electron microscopy and elemental analysis was determined. The introduction of hydrophobic methyl and benzyl groups into the macromolecule of chitosan reduces the intermolecular interaction and hydrogen bonding, causes. This leads to an increase in the degree of polarization and better solubility of the functional groups of the product in the polar environment.

The paper presents the results of studying the conversion of a mixture of toluene: straight-run gasoline (T: SRQ)= 1: 1, modeling the conversion of reforming gasoline, in the presence of a composite catalytic system Ni/HMOR/SO42/ZrO 2 (CCS) and its components, activating the joint hydrogenation of aromatic hydrocarbons and isomerization disproportionate transformation of C 8+ components. It has been established that at atmospheric pressure, Т= 180 0 С and the ratio Н2/hydrocarbon= 8, the transformation of the mixture with the participation of CCS is characterized by 76.8% conversion of toluene, 77.1% conversion of С 8+ components of SRQ and the 44.7% yield of isomeric С 5-С 7 alkanes. Based on a comparison of the results of the T: SRQ conversion in the presence of individual CCS components and their mechanical mixture, a conclusion was made about the conjugated nature of the effect of the CCS components on the process and a mechanism for the occurrence of catalytic synergy in the process of conversion of the T: SRQ mixture was proposed.

Using gravimetric and electrochemical research methods, the corrosion-electrochemical behavior of carbon steel grade St3 in Kura river water has been. Gravimetric measurements were carried out under operating conditions of the Shemkir and Yenikend hydroelectric power stations for one year. Along with this, the ionic and bacteriological composition, as well as some physicochemical parameters of these waters were established. It revealed that St3 in the Kura water corrodes at a rate of (0.04÷0.05) g/m2•hour, which is characteristic of steel corrosion in fresh waters. In the atmosphere of hydraulic structures, steel corrodes at rather a low rate, i.e. (5÷6)10-3g/m2 hour. As a result of biochemical analysis, sulfate-reducing bacteria (SRB) were discovered in these waters, which are a dangerous organism that releases the corrosive substance of H2S. By taking the anodic and cathodic polarization curves, a quasi-stationary steel corrosion rate was established to be 0.06g/m2 h.

Currently, the production of high-octane gasoline with …
Currently, the production of high-octane gasoline with low aromatic content is one of the main challenges in the petroleum refining industry and largely determines the development of this industry. The straight run gasoline (SRG) contains a certain amount of normal or slightly branched paraffinic hydrocarbons with low knock resistance; octane number of such gasolines is small (~ 60). Increasing gasoline octane characteristics performed by dividing SRG fraction with initial boiling point-85 0 C into two stream, one of which is subjected to high temperature dehydrocyclization processing (reforming), with a yield of high-octane number aromatics, exceeding 55%, and then it add to the remaining part of SRG. Otained this way gasoline requires additional oxygenate additives (MTBE, ETBE etc.), since the addition of C5-C6 fraction subjected to isomerization to obtain high octane isomers does not produce the gasolines with required octane properties. However, the fraction contained C5-C6 hydrocarbons going to isomerization, the C7+ hydrocarbons included in the straight-run gasoline limit this process and in the isomerization conditions over 30% of these hydrocarbons are converted in the side C1-C4

Analytical viewing on the pertinent investigations provide distinct and valuable information on different types of hydrocarbons placed in a diesel fuel. So, the variety hydrocarbon type content in the diesel fuel is considered in terms of its impact on the fuel performance characteristics, such as cetane number, diesel index, solidification temperature point, etc.[1]. It is inferred and postulated in the article that the data obtained are not sufficient to form full and complete description of the fuel. Thus, the additional information on the ratio of mono-and bicyclic arenes, low-molecular-weight alkanes, iso-paraffins, ie the quantitative data on individual hydrocarbons in the fuel composition are needed [1]. The hydrocarbon content of the once-run and hydrofined diesel fuels (summer and winter patterns) produced by direct disposal by“LukOil Nizhny-Novgorodpetroleumsynthesis” LLC is considered in terms of its effect on low temperature properties [2]. It was found that the straight-run diesel fuel chilling temperature depends on the ratio between light fractions which make up to 20% of the total fuel content and heavy high molecular weight cycloalkanes. Factors that determine the required pour point for the hydrofined diesel fuels of the summer and winter seasonal modes are constituent fractions making up 40 and 50%, respectively.

В рамках теории функционала плотности (DFT) моделированы свойства гексагонального моносульфида галлия (GaS) с учетом влияния вакансий, связанных с ближнеупорядоченной структурой. Показано, что электронное облучение монослоя GaS приводит к уменьшению проводимости за счет образования точечных дефектов. Рассчитаны зонная структура, плотность состояний и энергетические свойства суперъячеек GaS с 36 и 48 атомами с моновакансиями. DFT-расчетами получены значения энергии образования GaS и вакансий атомов Ga и S, а также определена степень влияния вакансий на свойства. С учетом фазовой диаграммы Ga–S изучено влияние состава соединения GaS на величину химического потенциала.

The boundaries of stable and metastable states of solid solutions of the MnTe-Sb2Te3 and SnTe-Sb2Te3 systems were determined by solving the thermodynamic equations of phase equilibria using the multipurpose genetic algorithm (MGA). As initial information, we used a small amount of experimental data from DTA and X-ray diffraction analysis, and thermodynamic functions of formation of MnTe, SnTe, Sb2Te3, MnSb2Te4, MnSb4Te7 SnSb2Te4, and SnSb4Sb7 compounds. The temperature-concentration dependences of the Gibbs energy of the formation of solid solutions from binary compounds, as well as from simple substances in quasi-binary sections, were determined using a subregular model of solutions of nonmolecular compounds as applied to telluride systems. The coordinates of the boundaries of metastable and stable solid solutions, in contrast to the entropy, are not very sensitive to the error in …

Oxidative condensation of methane (OCM) is one …
Oxidative condensation of methane (OCM) is one of the promising methods for processing natural gas into an ethane-ethylene mixture. A limiting factor in the practical implementation of the process is the low yield of target products. The best catalysts make it possible to obtain selectivity for C2-products up to 70-80% at a methane conversion of 25-30%[1-2]. A tempting approach based on a combination of the OCM reaction to produce ethylene and carbon monoxide in the reaction products with the required CO/C2H4 ratio with the hydroformylation reaction of this mixture to propylene is used in project C123 of the EU Horizon2020 program. This work presents the results of testing nanostructured oxide systems MnNaW/SiO2 as catalysts for the OCM reaction to obtain gas-phase mixtures with an equimolar ratio C2H4/CO, and discusses the structural and catalytic features of the synthesized systems. a) b) c) Figure 1.

Данная работа посвящена изучению математической модели для оптимизации процесса получения тонких пленок Bi-Se электрохимическим методом. Исследование проводилось потенциодинамическим, потенциостатическим и гальваностатическим методами, в различных условиях на Pt и Ni электродах. Математические расчеты были выполнены в программном пакете с использованием специально разработанного для этого процесса программного обеспечения. С изучением влияний различных факторов (концентрации исходных компонентов, температуры, плотности тока и т.д.) были выбраны оптимальный режим электролиза и состав электролита для процесса совместного осаждения. По этим результатам для будущих целей были назначены критерии Снедоккора и Фишера и оценены коэффициенты регрессии. Полученное уравнение регрессии определяет содержание электролита и условия электролиза, которое позволяет осаждать сплав Bi-Se, содержащий в составе необходимое количество Bi.

Mathematical calculations have been carried out using the Optum ME package program with the study of some factors as current density, concentration of main components, temperature, etc. which effect on the co-deposition process. Three independent variables have been selected. The amount of molybdenum in the deposit has been chosen as the dependent variable. The developed regression equation quite adequately describes the co-deposition process of nickel with molybdenum and can be used at planning the works on obtaining alloys with the required composition by the electrochemical method.

Theoretical studies of processes of oily wastewater …
Theoretical studies of processes of oily wastewater treatment for removing various impurities determined the main mechanism of the formation of coagulation structures and aggregates with their subsequent settling and phase separation, which disturb the aggregation and kinetic stability of the medium. It was found that a more advanced coagulation leads to the destruction of interlayers of the medium between particles, which brings the particles into direct contact with each other. This results in the formation of rigid aggregates with fractal structure, which consist both of hard particles, and of asphaltenes and resins, sometimes shaped as flakes. If the particles coagulate in a turbulent flow, their number decreases, although their sizes increase up to the sizes of aggregates. It was noted that the formation of coagulation structures is beneficial for separation of the solid phase from the liquid phase in wastewater treatment …

The phase diagram of the Cu2SnS3-Cu2SnSe3 system …
The phase diagram of the Cu2SnS3-Cu2SnSe3 system was plotted by thermodynamic calculations. Experimental data from differential thermal (DTA) and X-ray diffraction (XRD) analyses have used for the calculation. From the fundamental principles of thermodynamics for heterogeneous equilibria, new equations have been obtained for the direct calculation of the coordinates for (Cu2SnS3) 1-x (Cu2SnSe3) x liquid and solid solutions. The parameters of the analytical dependencies of the Gibbs free energy within the asymmetric version of the model of regular solutions were determined by means the multipurpose genetic algorithm (MGA), whereas the boundaries of solid solutions are determined based on Gibbs function for the internal stability. Analytical dependencies between the variables and formation thermodynamic functions for the compounds allowed us to estimate the sensitivity of the calculated data with the input data. It was established that, the coordinates of the liquidus and solidus curves are insensitive to formation enthalpy of the Cu2SnS3 and Cu2SnSe3 compounds. At the same time, a high sensitivity of the liquidus and solidus coordinates to the excess free energy values of solutions was observed. A 3D model of the Gibbs energy dependences on compositions and temperatures was visualized.

DILGAM TAGIYEV, ASMET AZIZOVA, MIRSALIM ASADOV Nagiyev Institute of Catalysis and Inorganic Chemistry 1143 Baku, H. Javid ave. 113 AZERBAIJAN dtagiyev@ rambler. ru Abstract:-Recently, a keen interest of researchers has been caused by the purposeful construction of compounds based on multinuclear complexes of transition metals as a new range of molecular biologically active substances. The analysis according to known datum of investigation of mixed ligand complexes (MLC) of the transition d-metals indicates that their constitutions and structures depend on condition of synthesis, nature of donor atoms and initial compounds of d-metals. In presented paper the results of physico-chemical investigation of synthesized individual and mixed ligand platinum (II) complexes with ethylene-aminoacetic and mercaptoacetic acids were given. The technique of synthesis of individual and mixed ligand platinum (II) complexes with ethylene-diaminoacetic and mercaptoacetic acids has been developed. The structures, thermoprecipitation processes and physico-chemical properties of the mentioned compounds have been studied by elemental analysis, IR-spectroscopy, thermography and conductometric method. When the obtained complex compounds interact with test-microorganisms they indicate antimicrobial activity.

The technology of hydrocarbon processing, in addition …
The technology of hydrocarbon processing, in addition to methane, also implies the involvement in the processing of its higher homologues-hydrocarbons. Currently, non-oxidative methods are being developed for gas feedstock processing, including their dehydrogenation to olefins. Technological schemes for the process of oxidative dehydrogenation of hydrocarbons are diverse and depend on the method of carrying out the process-continuous or periodic. This article presents the results of the development of modeling and determining the optimal parameters of the catalytic continuous processing of hydrocarbons on the example of oxidative dehydrogenation. On the basis of the constructed mathematical model of the kinetics of the process of oxidative dehydrogenation of hydrocarbons, the problem was solved by constructing a theoretically optimal temperature profile. Our laboratory data on the oxidative dehydrogenation of n-butane to divinyl and isopentane to isoprene were used as initial data when choosing a model, constructing an algorithm and calculations. This made it possible to identify the optimal regions of the regime parameters of the studied processes.

When the platinum(II) and palladium(II) salts interact with ligands such as cystamine-(mercamine) HSCH2CH2NH2 and 2-mercaptoethanol HSCH2CH2OH under certain conditions, polynuclear complexes of the compositions are obtained: [Pt6(SCH2CH2NH2)8]Cl4. 5H2O and [Pd6(SCH2CH2OH)8]Cl4. In a comparative study of the IR and X-ray spectra of synthesized complexes and ligands, as well as the results of X-ray diffraction studies, it was established that sulfur atoms of 2-mercaptoethanol occupy a bridge position with a mixed coordination of ligands in the palladium complex. In the platinum(II) complex bidentate coordination of ligands is realized through sulfur and nitrogen atoms.

Current work will present the results of a numerical solution of the problem of diffusion and convective transport in a multicomponent and multiphase system. On the example of a catalytic heterogeneous process of oxidative dehydrogenation of cyclic hydrocarbons, a numerical simulation of transport effects was carried out by finite-element approximation of the transport equations. The systems of the transport equation were based on experimental regularities describing transport processes. We have studied the convective-diffusive transport of a multicomponent phase in the catalytic dehydrogenation of cyclic hydrocarbons.An approximate solution of the transport equations is obtained around the catalyst granule for the convective-diffusion transport model. This allows to reduce the problem of multicomponent diffusion to the ordinary equation using the effective diffusion coefficient. We have compared the theoretical …

The paper deals with research into cathode reduction of thiosulfate ions on Mo electrode. Studies have been carried out in potentiometric regime at 298-358K temperature intervals. It revealed that rise in temperature facilitates the cathode process. The effective activation process energy (Aef) has been calculated and the nature of polarization identified on the basis of polarization curves. It found that this process is limited by electrochemical polarization. Also, the impact of concentration of thiosulfate ions (0.1-0.5 M) and development of potential (0.005 0.5 V/s) on cathode process of the reduction of thiosulfate on Mo -electrode has also been studied. It established that reduction of thiosulfate ions on the Mo electrode has to be carried out at high values of both factors.

Еxperimental results on the oxidative dehydrogenation of isobutane in the presence of vanadium-containing oxide and nanostructured catalysts are presented. The features of the structures of catalytic systems on the efficiency of their action on the activity and selectivity of the dehydrogenation process are studied. Oxidative dehydrogenation of isobutane, an industrial promising process for the preparation of isobutylene, was studied in the presence of vanadium oxide catalysts deposited on the surface of γAl2O3 by decomposition with organometallic complex compounds of vanadium (III) and (V). The catalytic effect in the target and side reactions is compared with the results of studying the characteristics of their volume and surface by X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed hydrogen reduction, and a number of others. Physicochemical method of investigation established that, depending on the initial vanadium metal complex taken, either the amount of reactive mobile oxygen increases or decreases, thereby promoting more efficient course of the oxide-reduction cycle and more stable operation of the catalyst.

In recent years increasing interest to methanol as an effective means to produce a ecologically clean fuel, available and cheap raw materials for the synthesis of various hydrocarbons and products of their processing. The most accessible and cheap raw material for the obtaining of CH3OH are natural and associated gases, from which by Fischer-Tropta's method it is possible to obtain hydrocarbons of different composition and structure. The formation of gasoline from methanol, developed in the present time flows through the stage of formation of DME, which turns further into the mixture of hydrocarbons consisting more than 50% of the valuable branched paraffins. Such" methanol" fuel in their composition does not contain sulfur and nitrogen compounds and a minor amount of aromatic compounds. Now, methanol increasingly became used as fuel and also as additives to motor fuels (from 3 to 65%). Methanol …

Обсуждено влияние электронных и пространственных эффектов в образовании основных продуктов-динитрила и имида при парофазном каталитическом окислительном аммонолизе о-ксилола и его 4-замещенных. Показано, что индуктивные эффекты заместителей и электроноакцепторные свойства фенильной группы не только обусловливают образованию динитрила, а также способствуют формированию соответствующего имида, что связано с разрывом наиболее слабой боковой С-Н-связи метильной группы, находящейся в α-положении к ароматическому ядру при первичном взаимодействии с металлоксидным катализатором, а пространственные эффекты орто-метильных заместителей субстратов только благоприятствуют получению имида за счет внутримолекулярной циклизации.

The complexing ability of platinum(II) and palladium(II) with various oxygen-sulphur and nitrogen-sulphur donor-containing ligands in various combination of their functional groups have been studied. With this it is found that during complexing not less important role belongs to nature of the primary metal salts, the pH medium, the nature of the solvent and the ratio of reactants. Actual dentaty of thiodiacetic, thiodipropionic acid, mercaptoethanol, and bis -b-hydroxy-ethyl sulphide was determined. Upon finding that during the reaction the cystamine molecule is split into S-S bond and the resulting deprotonated mercamine enters into complexing. In the non-aqueous medium the cleavage of S-S bond does not occur

Как известно, гетерогенный каталитический окислительный аммонолиз о-ксилола и его 4-бром-и 4-фенилзамещенных приводит к динитрилам и имидам, которые являются весьма ценными соединениями для органического синтеза [1]. Направление же окислительного аммонолиза о-ксилола и его 4-бром-и 4-фенилпроизводных в сторону получения динитрила либо имида в значительной мере определяется наряду с другими факторами и природой используемого катализатора [2]. Важно отметить, что при окислительном аммонолизе о-ксилола и его 4-бром-и 4-фенилзамещенных получается имид непосредственно из субстрата и гидролизом динитрила, а динитрил как промежуточный мононитрил, так и аммонолизом имида [3, 4].

Основными продуктами окислительного аммонолиза о-ксилола и его 4-бром-и 4-фенилпроизводных в присутствии ванадийсодержащих сложнооксидных контактов, в том числе на V-Sb-Bi/?-Al2O3-оксидном катализаторе, являются соответствующие динитрилы и имиды о-фталевой кислоты-весьма ценные соединения для органического синтеза [1, 2]. Одновременное их присутствие в катализатах в виде высокоплавкой, труднорастворимой кристаллической массы значительно усложняет технологию разделения, что отрицательно сказывается на эффективности процесса в целом. Присутствие на поверхности базовой V-Sb-Bi системы ионов V5+ и V4+ в условиях окислительного аммонолиза подтверждено физикохимическими методами [3].

In the course of methane conversion into benzene (MCtB) over Pt, ReOx/Al2O3 catalysts prepared by various methods the interactions between reactant and the catalyst has been studied. Unlike a sample prepared by impregnation, the sample prepared by chemical adsorption has shown high MCtB activity which yield of benzene~ 16% and selectivity> 75%. The results of H2-O titration on the size of platinum particles (1.0 nm and 14.0 nm) and surface state it has been shown that: i) Pt is modified by bound oxygen; ii) Oxygen bound by Pt of high dispersion exhibits the non-uniform reactivity. Due to interaction between Pt and Re these properties are transferred to oxygen of Re oxide which in turn partially participate in formation of C2HY intermediates. Further oligomerization and dehydrocyclization of C2HY proceeds with the participation of carbonaceous deposits

The influence of air oxygen on dehydrogenation …
The influence of air oxygen on dehydrogenation of ethylbenzene to styrene on promoter and non-promoter К2СО3 alumocopper catalysts at atmospheric pressure and 600 C has been studied. It has been shown that an availability of oxygen allows to increase weight rate on ethylbenzene from 0.3 to 2.0 h-1. On promoter catalyst a conversion of ethylbenzene in use of mixture ethylbenzene: О2= 4: 1reaches 52% at selectivity of formation of 92%A production of styrene (St), output of which exceeds 25 mln t.[1], is one of the largest industrial processes and it is characterized by high energy intensity. In this connection a growth of consumption of St requires a search of catalysts of dehydrogenation of ethylbenzene (EB) to St with the improved properties [2]. The thermodynamic restrictions of reaction of preparation of St by dehydrogenation of EB complicate its more effective realization. A selectivity of formation of St falls …

In the n-butane to isoparaffins conversion cobalt …
In the n-butane to isoparaffins conversion cobalt containing sulfated mordente-zirconium catalyst prepared with the use of zirconyl nitrate manifests higher activity and selectivity in comparison with the one obtained with the application of a zirconium hydrogel. The analysis of the diffuse reflection spectrums of Co-containing catalysts allows to assume that the cobalt coordination state depends on composition and of the catalysts preparation method, as well as on nature of the initial cobalt and zirconium compounds used in the catalysts synthesisIn the works [1, 2] it was shown that the dealuminized mordenite modifying with zirconium dioxide and sulfate ions leads to a substantial increase in the izomerizing activity of mordenite. In this case the activity and selectivity of catalysts with respect to isoparaffins depends on the method of their preparation [2]. It was also established that the introduction of cobalt into the …

Lower alkanes C2-C4 being chemically low active …
Lower alkanes C2-C4 being chemically low active are mainly used as fuel material. However, in some oil extracting and oil refining zones the accumulation and desirable consumption of such hydrocarbons is technically hindered. Therefore, they are destroyed by burning on torches. In this case, not only hydrocarbon feedstock is uselessly lost, but the environment in the regions with the torches is badly damaged. Thus, the rational use of the hydrocarbon feedstock is an important problem not only from the viewpoint of economy, but also from the ecological consideration. Taking into account the complexity of C2-C4 alkanes functionalization, one of methods of solution of this problem is the conversion of these alkanes into liquid hydrocarbons. The investigations in this direction showed the possibility of one-stage catalytic conversion of lower alkanes into aromatic hydrocarbons [1-3]. Taking into account the reactivity differences of C2-C4 alkanes, it is interesting to elucidate the reactivity of gas mixtures consisted of these molecules and their aromatic products. The present report is devoted to the results of studies in this direction.

Heterogeneous metal-complexes of the zero-valent nickel have …
Heterogeneous metal-complexes of the zero-valent nickel have been synthesized by ligand exchange between triphenylphosphine or hexaethyltriamidophosphine Ni (0) complex and chemically modified by method of immobilization support-silica, containing complex forming-NPR2-group, where R is Ph or NEt2. The comparative characteristics of the activity of these catalysts and their homogeneous analogues in ethylene oligomerization are given. It is shown that various factors (pressure, temperature, molar correlation Al/Ni) do not significantly influence the selectivity of this process in the presence of investigated heterogeneous metal-complexes.

Publisher SummaryThis chapter discusses a selective oxidation of propyl alcohols over zeolites modified with cations of the transition metals. Activity and selectivity of natural (pure and dealuminated clinoptilolite and mordenite) and A synthetic zeolites modified with cations of the transition metals are tested in vapor phase oxidation of iso-propyl and n-propyl alcohols. The efficient catalyst, CuPdH-mordenite has been selected for the oxidation of iso-propyl alcohol to acetone. This catalyst is not efficient in the oxidation of n-propyl alcohol. The catalyst prepared from A synthetic zeolites and containing palladium (Pd2+) and copper (Cu2+) shows the highest activity in this reaction.

Publisher SummaryThis chapter discusses benzene alkylation by propane using a zeolite-containing catalyst. The isopropylbenzene formation is shown to begin at 180–350°C over HY and platinum (Pt), rhenium /alumina (Re/Al2O3) admixed catalysts. The temperature increase leads to cyclopropane (C3H6) (250°C) and other alkylbenzenes (300°C) formation. The byproducts may be reduced by the selective poisoning of Brönsted acidic centres by ammonium. From the considerations on the reaction, the probable mechanism of benzene dehydroalkylation by propane has also been proposed.

The catalytic activity of Ni(II) bis-(5-thiopyrazol-4-aldiminates) was found to be related to the stereochemical flexibility of these compounds in the dimerization of propylene. The propylene conversion decreases with decreasing stereochemical flexibility of the complexes resulting from an increase in the bulk of the substituent at the coordinated nitrogen atom of the NiN2S2 chelate ring.

Preferential formation of di- or trimers of methylenecyclopropane (MCP) under the influence of Ni(O) complexes is determined by the nature of ligands, additions of modifiers, and the reaction conditions. The Ni(O) complex with coordinated P(NEt2)3 was synthesized via a proposed intermediate catalytic system Ni(COD)2-P(NEt2)3 by the interaction between Ni(η3-C3H5)2 and P(NEt2)3. The composition of the complex: {Ni[P(NEt2)3]2x} (K-1) was established by1H and31P-1H NMR, EPR spectroscopy, IR diffuse reflectance spectroscopy, and GLC. In the range 20–60‡C complex K-l only brings about trimerization of MCP. The catalytic properties of K-l were described earlier by a proposed scheme for the catalytic conversion of MCP under the influence of Ni(O) complexes.

1H and13C NMR, x-ray structural analysis, and magnetic moment measurements have shown that in 5-thio(seleno)pyrazolealdiminate complexes of nickel(II) based on tetradentate ligands containing the fragment, with n=2, flattening of the chelate unit takes place in solution and in the solid state. A similar structure in which the diamine metal-containing ring has the twist-chair conformation is observed for the crystals of the complexes with n=4. For the complexes with n=4 in solution at a temperature below −50°C, rapid (on the NMR time scale) interconversion of the flattened (P) (S=0) and pseudotetrahedral (T) (S=1) structures is observed, not accompanied by inversion of the tetrahedral configuration of the metal atom. At temperatures above −50°C, in addition to the low-barrier reactions (T) ⇄ (P), conversion of the seven-membered saturated metal-containing ring and inversion of the tetrahedral configuration of the …

В последние годы большое внимание уделяется исследованию процессов, позво-ляющих аккумулировать солнечную энергию посредством фотоэлектрохимического и фотокаталитического разложения воды на водород и кислород. Одним из перспек-тивных и эффективных фотоэлектродов-фотокатализаторов считаются модифици-рованные различными способами полупроводниковые материалы [1-5]. Модифици-рование поверхности полупроводниковых электродов способствует изменению энергетического спектра и плотности поверхностных электронных состояний, уменьшению скоростей поверхностной рекомбинации и побочной реакции, увеличению истин-ной поверхности электродов, расширению спектральной фоточувствительности усилению фотоэлектрокаталитического эффекта на границе раздела фаз [6-8]. В дан-ной статье приводятся результаты исследования электрокаталитического поведения поликристаллического TiO2, модифицированного металлсодержащими цеолитами при фотоэлектрохимическом разложении воды. Использование цеолитов в электрод-ной системе обусловлено прежде всего их высокой сорбционной способностью по отношению к ОтНп группировкам, в частности к воде [9, 10]. иВ состав цеолитов путем ионного обмена с использованием соответствующих аммиачных комплексов было введено небольшое количество (0, 1-0, 5 мас.%) ионов металлов Pt, Pd и Ru. Металлсодержащие цеолитные фотоаноды (S= 2 см²) в виде таблетки, полученные путем прессования поликристаллического ТіО2 с …

(КСМ-6П, КСМ-5), среднепористый (КСС-3) и крупнопористые (КСК-2, КСК-2, 5) промышленные образцы. Катализаторы на их основе были при-готовлены путем пропитки водными растворами азотнокислых или сер-нокислых солей различных металлов. Затем катализаторы обрабатыва-ли растворами ортофосфорной кислоты соответствующей концентрации при комнатной температуре и прокаливали при 500 С. Количество ок-сидов металлов, содержащихся в составе синтезированных катализаторов, определено объемным комплексонометрическим методом [3], а количе-ство фосфора-фотометрическим [4]. Удельную поверхность образцов определяли хроматографическим методом по тепловой десорбции азота. Термогравиметрические исследования осуществляли на дериватографе МОМ (Венгрия). Количество отлагающихся на катализаторах продуктов уплотнения (ПУ) определяли методом ДТА. Количество углерода, водо-рода и кислорода в продуктах уплотнения определяли методом элемент-ного анализа. Концентрацию парамагнитных центров в ПУ оценивали по спектрам ЭПР, снятым на радиоспектрометре IES-рЕ-ЗХ.

Oxidative conversion of olefinic, alkyl aromatic and …
Oxidative conversion of olefinic, alkyl aromatic and naphtenic hydrocarbons over zeolites is sensitive to the zeolite structure and dealumination degree as well as to the nature and concentration of exchange cations. Molecular sieve properties of zeolites were found to have a pronounced effect on the direction of oxidative hydrocarbon conversion and catalyst selectivity. Paujasite type zeolites are found to be very active and selective in the isoprene formation. Narrow pore zeolites exhibit higher selectivity in oxidative dehydrogenation of ethyl benzene than faujasites. Interaction of hydrocarbons and oxygen with various zeolites has been studied by thermodesorption technique. Mobility of zeolite oxygen has been evaluated by isotopic exchange and it has been found that it is not involved in oxidative dehydrogenation; the oxygen adsorbed from the gas phase takes part in the reaction. Catalytic properties of zeolites …

This paper reports on a study of the isotopic exchange between beryllium, calcium, magnesium, strontium, and barium silicates (MO.SiO/sub 2/) and molecular oxygen and shows that the exchangeable oxygen is a small proportion (0.1-3%) of the surface oxygen. The paper reports on the establishment of the equivalence of the exchangeable oxygen with respect to exchange with /sup 18/O. The authors indicate that the oxygen in the free alkali-earth metal oxides which form a separate phase on the surface of the MO.SiO/sub 2/ primarily participates in the exchange. Finally, they state that the modification of MO.SiO/sub 2/ with phosphorus results in a decrease in the mobility of the oxygen. (MO.SiO/sub 2/ silicates are typical catalysts of reactions of the acid-basic type.)

The effect of the composition and structure of the zeolite component on the activity of zeolite-containing catalysts in the production of small olefins by the pyrolysis of low-quality gasoline. The experiments were carried out in a laboratory flow system with a fixed catalyst bed. The catalysts had a magnesium silicate carrier containing different cationic forms of y-type synthetic zeolites, chabazite, erionite, and mordenite, as well as a natural clinoptilolite zeolite obtained from the Aidag deposit in the Azerbaidzhan SSR. The hydrocarbon raw material was a low-quality Karachukhur gasoline with an octane rating of 42. The experiments were carried out in the range 550/sup 0/ to 650/sup 0/C and volumetric flow rate of the liquid raw material of from 1 to 5 h/sup -1/. The gaseous reaction products were analyzed chromatographically. The major factors affecting olefin formation in the presence of zeolite-containing catalysts are the temperature of the pyrolysis of the liquid hydrocarbons and volumetric flow rate of the raw material. 2 figures, 1 table.

The effect is studied of the composition …
The effect is studied of the composition and structure of zeolite catalysts on their activity in the process of producing low-molecular olefins by pyrolysis of low-quality benzines. Used as thecatalyst are Na- or Na, K-forms of synthetic zeolites type A, X, Y, chabazite, eronite and mordenite. The experiments are performed on a flow-through laboratory unit with an immobile layer of catalyst. Before the experiment, the catalyst is roasted in an air current at 550 degrees. Pyrolysis is done in the presence of a gas-carrier at 550-650 degrees and volume speed of the liquid raw material of 1-5 per hour. The raw material is karachukhursk benzine with an octane number of 42. The greatest low-molecular olefin yield is observed using mordenite zeolite. With an increase in the volume speed of liquid raw material, the yield of gaseous products declines, while the HO content in the gas composition increases., The most active cation form of the synthetic mordenite is the Ni-Co form.

1. A study has been made of the thermodesorption of cyclohexane from zeolites of various structures and from cationic and decationized forms of zeolite Y. Each cyclohexane thermodesorption spectra showed a single peak. 2. Exchange of Na for Li, and Mg, and increase of the degree of decationization of the Y zeolite to 75%, had practically no effect on either the temperature of the maximum on the thermodesorption peak or the value of the effective diffusion coefficient. 3. A study of the thermodesorption of cyclohexane, cyclohexene, cyclohexa-1, 4-diene, and benzene from the Li-form of zeolite Y showed the temperature of the maximum on the thermodesorption peak to be shifted toward higher temperatures, and the effective diffusion coefficient reduced, by an increase in the degree of unsaturation in the hydrocarbon molecule. 1980 Plenum Publishing Corporation.

Oxidative dehydrogenation of cyclohexane over cationic zeolites …
Oxidative dehydrogenation of cyclohexane over cationic zeolites was studied in a flow reactor at 300/sup 0/-450/sup 0/C, 1 atm, 1/hr liquid space velocity, and 0.5:1-1.5:1 oxygen in air/cyclohexane. Over all the catalysts studied, cyclohexene was the main reaction product formed with 62-84Vertical Bar3< selectivities. Benzene and 1,3-cyclohexadiene, products of oxidative dehydrogenation of cyclohexene, and carbon dioxide, were also formed in low yields. The highest cyclohexene yields at 450/sup 0/C were over the NaA zeolite (21.2Vertical Bar3<), Na,K-shabasite (20.5Vertical Bar3<), and Na,K-erionite (19.2Vertical Bar3<). Mordenite and Na,KL zeolite had lower activities. A decrease in the reaction temperature or introduction of copper, iron, or palladium ions to erionite increased the yield of benzene and decreased the selectivity for cyclohexene. A kinetic study suggested that a surface reaction between adsorbed cyclohexane and weakly adsorbed molecular oxygen is the rate-limiting step. At 450/sup 0/C and 1:1 oxygen-cyclohexene, the yields of 1,3-cyclohexadiene in oxidative dehydrogenation of cyclohexene was 7.7Vertical Bar3< over Na,K-shabasite, and Vertical Bar3; 3.4Vertical Bar3< over the other catalysts, with 7-48Vertical Bar3< selectivities.

Метод термодесорбции, нашедший широкое применение при исследова-нии взаимодействия молекул реагентов с поверхностью твердых тел [1, 2], до сих пор мало использовался при изучении цеолитных катализаторов [3]. В данной работе изучена термодесорбция 2-метилбутена-2 (МБ) Па-форм цеолитов типа А, Х, Ү, шабазита, эрионита, L и морденита, каталитическая активность которых в гидрировании 2-метилбутена-2 исследовалась в [4]. Наблюдавшаяся в этой работе зависимость катали-тической активности цеолитов от соотношения окислов кремния и алюми-ния в них могла быть обусловлена внутридиффузионным торможением реакции в случае узкопористых цеолитов типа А, шабазита, эрионита, морденита. Проверка этого предположения и явилась целью данного исследования, в котором на основе найденных коэффициентов диффузии молекул МБ в цеолитах рассчитаны факторы эффективности катализато-ров.

Катионные формы цеолитов каталитически активны в гидрировании амиленов [1-3]. Для выяснения природы активных центров этих ката-лизаторов в реакции гидрирования представляет интерес исследование активности как цеолитов различной структуры, содержащих один и тот же катион, так и цеолитов одного типа, но содержащих катионы различ-ной природы. Результаты исследования гидрирующей активности Na-форм цеолитов изложены ранее [1]. В настоящей работе исследована зависимость гидрирующих свойств цеолита типа Ү от природы и содержания других катионов. Поскольку насыщенные углеводороды на декатио-нированных и поливалентных катионных формах цеолитов могут образо-вываться не только гидрированием олефинов, но и в результате реакции перераспределения водорода, одновременно с гидрированием 2-метилбу-тена-2 (МБ-2) исследовано его превращение на тех же катализаторах под давлением гелия.

In recent decades, significant advances have been made in quantum chemistry due to increasingly powerful computing resources and the development and implementation of advanced research methods. Thus, quantum chemical calculations, especially those using density functional theory (DFT), have become an important tool in many areas of chemistry. In this paper, oligomers of chitosan and polyvinylpyrrolidone are studied using DFT method and the possibilities of forming complexes of these oligomers with transition metals, in particular, with silver, are considered. In the course of the work, molecules of PVP and chitosan oligomers with the number of monomers n= 1-10 are optimized. The values of their electronic characteristics are presented. The molecular electrostatic potential (MEP) surfaces and Mulliken charges are analyzed. Based on the data obtained, active centers for predicting complex formation, stability and reactivity of molecules are discussed. It was found that in the chitosan molecule the best area for interaction with the metal are nitrogen and oxygen atoms, in the PVP molecule—oxygen atoms. In this regard, when optimizing the expected complexes, the metal atom was placed close to the corresponding nucleophilic sites. As a result, silver complexes with monomers of chitosan and PVP were obtained. Electrostatic and donor-acceptor interactions in the system were revealed. To understand the process of formation of organometallic complexes, an analysis of electrostatic potentials, boundary orbitals of the predicted complexes was also carried out, the stability of the complexes was estimated and the energies of their …

The use of carbon-based energy sources leads to the formation of carbon dioxide, which significantly contributes to rapid environmental pollution. Therefore, the production of green hydrogen as a" clean" energy carrier is particularly important, as it can be obtained directly from renewable energy sources through water electrolysis. It is well known that electrodes made from noble metals exhibit the highest activity in the hydrogen evolution reaction (HER). However, their high cost prevents widespread industrial-scale application for hydrogen production. To enable a cost-effective, environmentally friendly, and sustainable hydrogen economy, it is crucial to produce hydrogen at a lower cost. The development of new, inexpensive electrocatalytic materials capable of efficiently facilitating electron transfer in hydrogen evolution (HER) and oxygen evolution reactions (OER) at low overpotentials is of paramount importance. This review summarizes the historical background, challenges, and significance of hydrogen production through water electrolysis, addressing its past, present, and future prospects. It compiles the latest advances in overcoming HER kinetic barriers and synthesizing new, efficient catalysts based on binary and ternary alloys of nickel and other iron-group metals as alternatives to noble-metal electrodes. Iron group metals and their alloys are among the potential candidates that can meet most of the requirements for electrodes in the hydrogen evolution reaction (HER). The development of low-cost and highperformance electrocatalytic materials made from inexpensive and abundantly available elements, which can be easily produced on …

Zinc arsenides are promising semiconductors due to their natural abundance, unique electronic properties such as high carrier mobility and structural anisotropy and significant potential for advancing sustainable technologies. In light of discrepancies in existing literature and the growing relevance of these compounds, this study presents a thermodynamic investigation of ZnAs2 and Zn3As2 within the temperature range of 300-440 K using the low-temperature electromotive force (EMF) method. Equilibrium samples from the ZnAs2+ As and Zn3As2+ ZnAs2 two-phase regions of the Zn-As system were utilized, with phase compositions confirmed by powder X-ray diffraction analysis. The experimental data enabled the calculation of partial molar functions of zinc in the alloys, as well as the standard thermodynamic functions of formation and standard entropies for ZnAs2 and Zn3As2 compounds. A comparative analysis with previously reported data was conducted, providing insights into the thermodynamic behavior of zinc arsenides and improving the accuracy of existing knowledge.

The phase equilibria in the CuSbS2-Sb2S3-SbSI compositions intervals of the Cu-Sb-SI quaternary system have been investigated by differential thermal analysis and X-ray phase analysis methods. The boundary quasi-binary section CuSbS2-SbSI, two internal polythermal sections of the phase diagram, as well as, the projection of the liquidus surface of the system were constructed. Primary crystallization areas of phases, types and coordinates of non-and monovariant equilibria were determined. It was established that, the system is quaternary and belongs to the nonvariant eutectic type. The liquidus surface consists of three distinct regions, each representing the direct crystallization of one of the primary compounds from the melt. These regions are separated by three eutectic curves defining the boundaries between them.

The paper reports the results of mathematical modeling and optimization of the process of obtaining thin films based on Mo-Re alloy by electrodeposition. The study of electrodeposition of Mo-Re alloys was carried out using methods of potentiodynamic, galvanostatic, and cyclic voltammetry under different conditions on a Pt electrode. Studies have been conducted using the method of planning experiments and a regression equation is obtained. Based on the experimental data, the obtained regression equation was analyzed, the Fisher criterion was calculated and the significance of the regression coefficients was estimated. To confirm the experimental results, based on the data obtained, the coefficients of the regression equation were refined, and the criteria of significance and adequacy were calculated. The calculations based on the experimental data indicate that the regression equation adequately describes the process of co-deposition of rhenium with molybdenum.

The conversion of C6H6: C3H8 mixtures on …
The conversion of C6H6: C3H8 mixtures on a mechanical catalyst mixture (MC) consisting of HY, HM or HZSM-5 zeolite and M, Re/Al2O3 was studied. As a result of propane activation in the presence of benzene on the catalytic system, the components of the benzene-propane mixture at low temperatures (473-673 K) are converted into alkylaromatic hydrocarbons C9 and propene. It was found that propane dehydrogenation to propylene occurs already at 523 K with benzene as a stoichiometric reaction component. Based on the obtained data on the dependence of the yield of propylene and isopropylbenzene on the experimental conditions, an assumption was made about a common intermediate compound preceding the formation of these products. Thermodynamically unfavorable reactions of benzene dehydroalkylation with propane and the process of propane dehydrogenation are explained by the occurrence of conjugate oxidation-reduction interaction due to cyclic proton transfer between the zeolite and partially reduced centers of the metal component of the MC and alternating oxidation and reduction of these centers. As a result of the studies, the effect of benzene on the low-temperature activation of propane on mixed catalysts consisting of a mixture of (50 x 50) M, Re/Al2O3+ H-zeolite, leading to the formation of isopropylbenzene, propylene and C9-alkylaromatic hydrocarbons, was established; the dependence of the yield of the conversion products of the C6H6: C3H8 mixture on the reaction conditions and the nature of the zeolite component of the mixed catalyst was established.

One of the best strategies to achieve environmentally benign energy production is photovoltaic technology. In modern times the predominant way to make PEC cells more competitive is by increasing their solar to hydrogen efficiency [1-2]. As the material for conversion solar energy Sb2Se3 has recently gained popularity due to its potential to have similar solar to hydrogen efficiencies to crystalline silicon. Sb2Se3 is a relatively cost-effective and reasonably abundant light-absorbing material, not listed as a “highly toxic” compound. Sb2Se3 exhibits a direct band gap between 1.04-1.3 eV and an optical absorption coefficient above 105 cm-1 in the visible region [3-6]. The aim of this work is to create corrosion-resistant semiconductor anode materials that are sensitive to the visible region of the solar spectrum.

Currently, the global community is actively striving to transition to renewable and alternative energy sources with the goal of reducing greenhouse gas emissions (CO2, NOx, SOx) by 60% by 2050. In this regard, hydrogen is considered as a promising energy carrier that can reduce the anthropogenic impact on the environment. It can be produced using a variety of sources, but the production and consumption cycle in this case should not lead to greenhouse gas emissions. This trend requires the development of lowcarbon strategies and technologies for hydrogen production from both mineral and renewable sources [1, 2]. The transition to hydrogen energy is inevitable, but which technologies will ultimately become most widespread is currently difficult to determine. To date, the most developed industrial method for producing hydrogen is steam reforming of methane, which, however, compared to other methods for producing hydrogen, produces the largest volume of carbon dioxide emissions into the atmosphere. However, using this method in autothermal mode, it is possible to obtain synthesis gas with a hydrogen content of up to 75 vol.%. In addition to hydrogen, the resulting synthesis gas contains up to 30 vol.% carbon oxides, which can be converted into methanol and thereby significantly reduce carbon emissions. To increase efficiency, a combination of two or more types of traditional conversion methods (steam, oxygen or carbon dioxide conversion) of natural gas into synthesis gas and hydrogen is used. Autothermal reforming developed by Haldor Topsoe, consisting of a combination of steam reforming and partial oxidation processes …

To provide the economy with clean and sustainable hydrogen energy, it is necessary to obtain hydrogen at a low price. Producing cheap hydrogen by electrolysis requires the development of new electrode materials with increased electrocatalytic activity for the hydrogen evolution reaction. Electrodes based on iron group metals with refractory metals are widely used as a material in water electrolysis, and the most studied electrode materials in water decomposition reaction (HER) are Ni-based alloys [1]. It is known that doping with phosphorus leads to distortion of the crystal lattice structure and the formation of amorphous materials [2]. Even a small amount of phosphorus, about 1%, has a positive effect on the microstructure, reduces residual tension in the film and improves the adhesion of the coating to the substrate [3, 4]. Co-precipitation of phosphorus with elements of the iron group helps to increase the corrosion resistance of deposits due to the protective film formed by phosphorus anions on the surface of the electrodeposited coating. Doping with phosphorus up to 1.0 mol% also improves the transmission of visible light by deposited films [4]. This paper presents the results of a study of the catalytic activity of electrodeposited binary (Ni-Co, Ni-P, Co-P) and ternary (Ni-Co-P) alloys deposited from an ammoniaglycine electrolyte. It has been established that an increase in the concentration of NaH2PO4 in the electrolyte leads to an increase in the phosphorus content in the composition of the thin film, and an increase in the current density leads to a decrease in the phosphorus content in the deposits. The introduction of phosphorus into the …

The production of hydrogen by water electrolysis …
The production of hydrogen by water electrolysis is one of the most promising methods for obtaining alternative fuel. Among differentelectrolysis methods, high-temperature electrolysis is considered the most promising. Electrochemical water splitting is an attractive method for hydrogen evolution. The main problem of this method is the search for electrocatalysts with high catalytic activity. Thereby, various effective electrocatalyst materials, including Pt and other noble metals, have been investigated. However, the high cost of Pt or other noble metals hinders their widespread use. Highly active, cheap and earth-abundant metals should be used as catalysts. In this regard, it was established that ternary compounds of rhenium with chalcogenides are active catalysts. Rhenium and its alloys can be used in various fields of science and technology—biotechnology, military affairs, medicine, environmental protection, etc. The main aim of the work is to obtain nano coatings in the system Re-Cu-Se on a nickel electrode by electrochemical method and their use as a catalyst for water electrolysis. For this purpose, the optimal conditions and electrolyte were determined for obtaining nanocoatings of the Re-Cu-Se alloy on a nickel electrode by electrochemical method. The crystal structure, thickness, phase composition, adhesion strength, dispersibility of the electrolyte, electroconductivity, voltammetric characteristics of thin nano coatings obtained on various electrodes in the Re-Cu-Se system by electrochemical method have been studied. The investigation of electrolytic deposition of Re-Cu-Se shows that the composition and quality of the obtained coatings …

Experimental results of studying the morphology, phase …
Experimental results of studying the morphology, phase composition, magnetic and catalytic properties of vanadium-antimony-containing aluminum oxide samples in the reaction of oxidative dehydrogenation of propane (ODP) with carbon dioxide are presented. It has been shown that in the X-ray diffraction patterns of vanadium-aluminum and antimony-vanadium-aluminum oxide catalysts with a vanadium content of less than 15 and an antimony content of less than 5 wt.%, respectively, only peaks belonging to γ-Al2O3 are observed. It is assumed that the absence of V2O5 peaks is due to the presence of vanadium oxide in these catalysts in a highly dispersed amorphous state in the form of polymer structures (VOx) n. In the X-ray diffraction patterns of the catalyst with the composition 5% Sb-15% V/Al2O3, peaks characteristic of the Sb2O3 and SbVO4 phases are observed. According to the EPR spectra, vanadium ions in the+ 4 oxidation state are identified as vanadyl ions VO2+. It has been shown that the introduction of antimony into the composition of a vanadium-aluminum oxide catalyst increases the amount of vanadyl ions VO2+ and its activity in the ODP reaction. It was found that samples of the used γ-Al2O3 carrier are inactive in the ODP reaction and acquire this activity after introducing vanadium into them. The introduction of antimony into vanadiumcontaining aluminum oxides enhances the catalytic activity and significantly increases their selectivity in the ODP reaction. The thermodynamics of the reactions of formation of vanadium-antimony oxide structures and ODP with their participation have been studied.

Currently, the synthesis of electrodes with catalytic activity in the water-splitting reaction and the enhancement of their electrocatalytic properties are crucial for hydrogen production via electrolysis. The generation of radiation defects on electrode surfaces due to ionizing radiation and assessing their impact on the catalytic activity of synthesized electrodes in hydrogen production by electrolysis of water is a significant scientific challenge.This study examines the effect of γ-radiation on the catalytic activity of binary (Ni-Mo) and ternary alloys (Ni-Mo-P), obtained using the electrochemical method from alkaline and alkali-citrate electrolytes. The alloys were analyzed before and after annealing in an air atmosphere at 773 K for one hour. It was found that under the influence of γ-radiation, the catalytic activity in the hydrogen evolution reaction in a neutral environment (0.5 M Na2SO4) increases by 12.2% for annealed Ni-Mo binary thin films, whereas the activity of non-annealed samples remains largely unchanged. For Ni-Mo-P ternary alloys, the catalytic activity decreases by 28.16% after annealing and γ-radiation exposure. This behavior of the catalysts is explained by changes in the crystal lattice of the resulting films under the influence of γ-radiation.

A systematic study of the hydrogenation of individual aromatic hydrocarbons (benzene, toluene, xylene) and their mixtures was carried out at 1800C, H2/Ar= 7, WHSV= 2h-1 and atmospheric pressure on a composite catalyst 0.4% Co/HZSM-5/SO4 2-(2.0%)–ZrO2. It has been established that the developed catalyst has a high hydrogenating ability with respect to aromatic hydrocarbons at low hydrogen pressures. Alkyl-substituted benzenes turned out to be more active. It was found that alkyl substituents increase the activity of hydrogenation of the benzene ring of an aromatic hydrocarbon. According to their conversion, benzene, toluene and xylene form the following sequence: benzene< toluene< xylene. It was found that the optimal temperature for the process of hydroconversion of aromatic hydrocarbons on a composite catalyst is 1800C. The influence of the concentration of the hydrogenating component of the catalyst–Co on the hydroconversion was also investigated. It was found that the optimal concentration of Co is 0.4 wt%. It has been established that in a benzene: toluene: xylene mixture, the conversion of benzene in comparison with its separate hydroconversion increases by more than 10%. The hydroconversion of aromatic hydrocarbons is accompanied by the formation of high-octane naphthenic hydrocarbons-cyclohexane, methylcyclohexane and methylcyclopentane. The antibatic change in the yield of CH and MCP with the duration of the experiment shows that the hydrogenation of the aromatic ring is primary and the isomerization of C6H10 to MCP is secondary, ie MCP is the result of a sequential transformation. The absence of …

In the title compound, C16H13Cl4N3, the dihedral angle between the benzene rings of the dichlorophenyl and dimethylaniline groups is 50.85 (13). The central–N= N–unit shows an E configuration. In the crystal, molecules form parallel layers to the (100) plane by C—H··· π and face-to-face π-π [centroid-to-centroid distances= 4.0538 (17) and 4.0537 (17) Å] interactions. These layers are connected by Van der Waals interactions to stabilize the crystal structure. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from Cl··· H/H··· Cl (36.4%), H··· H (23.3%) and C··· H/H··· C (15.2%) contacts.

This work presents studies to study the nucleation and growth mechanism of electrochemical Ni-Mo films suitable for the decomposition reaction of water as an electrocatalyst, in which the value of the potential established from polarization measurements was maintained constant. Optimal conditions for the electrochemical synthesis of the Ni-Mo alloy on the surface of platinum and nickel electrodes were established using voltammetric studies examining the influence of many electrolysis parameters on the process of co-deposition of nickel with molybdenum. The chronoamperometric method provides more detailed information about the electrodeposition process by studying the nucleation and growth mechanism of electrochemical films in which the potential value determined from polarization measurements was kept constant. The curves were taken at various potential values-0.1,-0.2,-0.3,-0.4,-0.5,-0.6,-0.7,-0.8 and-0.9 V at room temperature. The study of these curves can be carried out by comparing the experimental calculated data with the equations of the Scharifker-Hills model. It was found that in the early stage, at potentials of-0.1 and-0.2 V, the experimental data fit into the curve of the progressive nucleation model, according to which Ni-Mo nucleation occurs on many active areas of the substrate surface, but at other potentials (from-0.3 to-0.9 V) deposition deviates towards instantaneous nucleation and growth.

The electrocatalytic characteristics of Sb2Se3 thin films prepared by electrochemical technique were examined for the evolution of hydrogen by the electrolysis of water. The thermally treated Sb2Se3 samples obtained from a non-aqueous electrolyte were studied on the Ni electrode for determining their catalytic activity in the process of water electrolysis. According to the calculated, Sb2Se3 exhibit the lowest Tafel slope in comparison to Pt and Ni electrodes. According to photoelectrochemical investigations, these samples are light-sensitive and can be employed as a photocathode in the hydrogen evolution reaction. Extrapolating the C-2-E plot onto the potential axis results in a flat band potential Vfb of-1.45 V (compared to Ag/AgCl). The value precisely represents the electrodeposited p-type semiconductor Sb2Se3's thermodynamic capacity to generate hydrogen from water under given conditions.

Currently, an important ecological problem is environmental pollution and its negative impact on living organisms, the consequences of which are deterioration in general health and the manifestation of various diseases, poisoning, endo-and exotoxicosis. Enterosorption method was proposed as a promising method for removing toxic substances from the living organisms using enterosorbents which can absorb various toxic substances of endogenous and exogenous nature in the lumen of the gastrointestinal tract. It has been proposed to use polymer-containing enterosorbents for eliminating of heavy metals from the organism. The purpose of this research was to synthesize a quaternized derivative of chitosan, specifically N-(2-hydroxybenzyl)-N-ethyl-N-methyl chitosan chloride (Q-CHS). The synthesis of Q-CHS involved the formation of a Schiff base, followed by the quaternization of the amino group of chitosan (CHS). The structures of both pure CHS and quaternized CHS were studied using various physico-chemical methods, including FTIR, NMR, XRD, SEM, DSC and TGA analyses in order to determine the structure and confirm the formation of the final product.

In order to increase the resources of branched C5-C6 hydrocarbons with high octane number, the direct involvement of straight-run gasoline in a catalytic low-temperature joint isomerization and disproportionation process has been studied. The corresponding routes of the main and side reactions of the process of direct involvement of straight-run gasoline on the Me-HZSM-5-SO4 2-/ZrO2 catalyst to determine their rate constants, taking into account the complex composition of the feedstock, were described. The paper presents the results of the conversion of straight-run gasoline (SRG) at 140-200 C on the catalyst Co-HZSM-5-SO4 2-/ZrO2. It has been established that the products of SRG conversion are mainly C5-C6 alkanes, the yield of which reaches 53-66%, containing up to 79-88% of the iso-components during the conversion of C8+ paraffins 36-77%. Kinetic studies have been carried out to directly involve of straight-run gasoline in low-temperature isomerizationdisproportionation conversion of straight-run gasoline, and show reaction routes. Calculations of reaction rate constants depending on the conversion condition were carried out using the MATLAB program (STATISTICA). From the found values of the reaction rate constants using the Arrhenius equation, the activation energies are calculated. A kinetic model of the process is proposed

Complexation in various platinum (II) conditions with various sulfur-oxygen and nitrogen-oxygen containing ligands was studied for the first time. Individual and mixed-ligand platinum complexes with ethylenediamine diacetate and mercaptoacetic acid were obtained. With the help of IR and other physical methods, the methods of coordination of these ligands with the central atom have been studied. When synthesizing complexes, the selected conditions are optimal for individuality and high yield. It was found that in the complex [Pt (EDDA)(NH3) 2] Cl2, ethylene diamine diadiazate is bidentate at the nitrogen atom in the cis-position. Under these conditions, the carboxyl group of the ligand is not involved in complexation. In the complex [Pt (SCH2COOH) 2 (NH3) 2] mercaptoacetic acid is coordinated monodentatno at the sulfur atom in trans positions. The carboxyl group of the ligand also does not participate in coordination. In the complex [Pt (EDDA)(SCH2COOH) 2] ethylene diamine diacetate in bidentate coordination form a fivemembered metal-chelate cycle in the cis-position, this leads to the forced monodentate cis coordination of mercaptoacetic acid. In all synthesized complexes, the carboxyl group of ligands are not involved in coordination.Study of the thermal behavior of synthesized complexes I-III showed that the decomposition of complexes depending on composition and structure occurs in different ways. The complexes are stable up to a maximum of 3150 C. Cleavage of ligands occurs in two stages. Complex II is stable up to 315 С, as evidenced by a clear area on the TG curve, and then the complex decomposes at high speed. The …

The different catalysts for n-butane isomerization, among which Pt-Al 2 O 3-Cl, Pt-zeolites and SO 4/ZrO 2 (SZ)[1-3] are the most interested, are used. In spite of a number of advantages, zeolite catalysts conduct the n-butane isomerization at relatively high temperatures and in this respect concedes SZ. We showed that promotion of dealuminated H-mordenite with zirconium dioxide allows to increasing the isobutane yield and lowering the reaction temperature. In this work the results of investigation of influence of mordenite-zirconia catalysts preparation methods on their activity are presented.

The systems of indium tin oxide (ITO)/nanoporous anodized aluminum oxide Al2O3 (AAO) and ITO/CdS nano-structured were fabricated on transparent glass substrates by using radio frequency magnetron sputtering and electrochemical deposition. The glass/ITO/AAO samples were transparent for visible light that make them useful and efficient for PV solar cell applications. The effect of annealing on optical and electrical properties of ITO thin films has been studied. It is found that, the transparency of the ITO films is directly proportional to the oxygen content of the plasma in the sputtering chamber and increased with annealing temperature, while the sheet resistance is inversely proportional to the annealing. In this work, it is found that, the electrochemically fabricated CdS thin films nanostructure of thickness of 200–500 nm is transparent and well absorbs the light over the wavelength wide ranged from 450 to 800 nm. Raman spectrum of CdS thin film obtained via backscattering geometry exhibits relatively sharp crystal-like peaks at 300 and 600 cm-1. The full width at half maximum value FWHM of Raman peak at the 300 nm is 40 cm-1.

Nanoparticle formulation development for drug delivery, a …
Nanoparticle formulation development for drug delivery, a crucial aspect of nanotechnology, encounters numerous challenges. These encompass selecting appropriate excipients, comprehending miscibility and solubility factors, ensuring efficient drug encapsulation and release, assessing stability, and facilitating drug transport in the bloodstream for accurate targeting and attachment. To address these intricate issues, a range of molecular computational models is utilized. These models include quantum mechanical simulations that handle the smallest particles and move through atomistic molecular dynamics for detailed molecular interactions, coarse-grained molecular dynamics (MD) for larger scale phenomena, and dissipative particle dynamics (DPD) for mesoscale modeling. Further scaling up, computational fluid dynamics (CFD) is used for fluidic behaviors, discrete element modeling for large particle systems, and both pharmacokinetic/pharmacodynamic (PK/PD) and physiologically based pharmacokinetic (PBPK) modeling for whole-body dynamics. These methodologies play a crucial role in elucidating the complex mechanisms involved in the development of nanoparticle formulations and are essential in the creation of varied organic and inorganic systems for drug delivery. This review primarily concentrates on these computational simulation models and their significance in the context of nanoparticle-based drug delivery systems.

Through the pyrazine-modulated tetrapyridyltriamine ligand N2-(pyrazin-2-yl)-N6-(6-(pyrazin-2-ylamino)pyridin-2-yl)pyridine-2,6-diamine (H3pzpz) (1), a new mononuclear copper(II) complex [Cu(H3pzpz)(NO3)]∙NO3∙3H2O (2) has been synthesized and structurally characterized. The copper(II) atom in complex 2 exhibits a distorted square pyramidal geometry with an Addison parameter value of 0.39 (σ = 0.39). In compound (2), H3pzpz (1) acts as a tetradentate N4-donor ligand and coordinates to the Cu(1) ion in an anti-anti-anti-anti conformation. The single crystal X-ray analysis revealed a distorted square pyramidal geometry of the complex (2), which is consistent with the parameters of EPR spectra, measured magnetic moment susceptibility, and electronic spectrum studies. Observed extensive intermolecular hydrogen bond interactions (classical and non-classical) play an important role in the formation of the 3D supramolecular network and crystal packing of this complex. The complex (2) has been identified as a promising building block for the construction of coordination polymers.

Comparative analysis of the structural parameters of …
Comparative analysis of the structural parameters of the substituted cyclopentadienyl moieties (tBuC5H4 and tBu2C5H3) of two binuclear molybdenum complexes ((tBuCp)2Mo2(CO)6 (1) and (1,2-tBu2Cp)2Mo2(CO)6 (3)) and two sandwich complexes of iron (the cation of 1,1-di-tert-butylferrocenium (tBuCp)2Fe+ (4) and 1,2,1,2-tetra-tert-butylferrocene (1,2-tBu2Cp)2Fe (5)) allowed us to identify the structural features of the tBu2C5H3 fragment in (3) and to establish the reasons that account for them. It is shown that the main changes in the structural parameters (valence and torsion angles, bond lengths) of the fragment 1,2-tBu2C5H3 are due to steric interactions of vicinal tBu-substituents between themselves, as well as with the corresponding nearest CH fragment of the ring. Differences in the degree of steric interaction of vicinal tBu-substituents with CH ring fragments in (3) are interpreted by the steric influence of the trans-carbonyl (C10O3) group on the tBu-substituent at C4. The latter interaction is also reflected in the larger value (26) of the rotation angle of the tBu-substituent at C4, compared to the rotation angle (15) of the corresponding tBu-substituent in (5), caused only by the steric interaction of vicinal tBu-substituents among themselves. In (3), the steric influence of the trans-carbonyl group on the tBu-substituent at C4 is also accompanied by a change in the direction of rotation of the tBu-substituent at C5, as a result of which the conformations of the tBu-substituents with respect to each other and to the ring plane differ markedly from the conformations of the tBu-substituents in (5). In the binuclear complexes of molybdenum (3 …

The paper reports the results of mathematical modeling and optimization of the process of obtaining thin films based on Mo-Re alloy by electrodeposition. The study of electrodeposition of Mo-Re alloys was carried out using methods of potentiodynamic, galvanostatic, and cyclic voltammetry under different conditions on a Pt electrode. Studies have been conducted using the method of planning experiments and a regression equation is obtained. Based on the experimental data, the obtained regression equation was analyzed, the Fisher criterion was calculated and the significance of the regression coefficients was estimated. To confirm the experimental results, based on the data obtained, the coefficients of the regression equation were refined, and the criteria of significance and adequacy were calculated. The calculations based on the experimental data indicate that the regression equation adequately describes the process of co-deposition of rhenium with molybdenum.

Current work will present the results of a numerical solution of the problem of diffusion and convective transport in a multicomponent and multiphase system. On the example of a catalytic heterogeneous process of oxidative dehydrogenation of cyclic hydrocarbons, a numerical simulation of transport effects was carried out by finite-element approximation of the transport equations. The systems of the transport equation were based on experimental regularities describing transport processes. We have studied the convective-diffusive transport of a multicomponent phase in the catalytic dehydrogenation of cyclic hydrocarbons.An approximate solution of the transport equations is obtained around the catalyst granule for the convective-diffusion transport model. This allows to reduce the problem of multicomponent diffusion to the ordinary equation using the effective diffusion coefficient. We have compared the theoretical …

В последние годы большое внимание уделяется исследованию процессов, позво-ляющих аккумулировать солнечную энергию посредством фотоэлектрохимического и фотокаталитического разложения воды на водород и кислород. Одним из перспек-тивных и эффективных фотоэлектродов-фотокатализаторов считаются модифици-рованные различными способами полупроводниковые материалы [1-5]. Модифици-рование поверхности полупроводниковых электродов способствует изменению энергетического спектра и плотности поверхностных электронных состояний, уменьшению скоростей поверхностной рекомбинации и побочной реакции, увеличению истин-ной поверхности электродов, расширению спектральной фоточувствительности усилению фотоэлектрокаталитического эффекта на границе раздела фаз [6-8]. В дан-ной статье приводятся результаты исследования электрокаталитического поведения поликристаллического TiO2, модифицированного металлсодержащими цеолитами при фотоэлектрохимическом разложении воды. Использование цеолитов в электрод-ной системе обусловлено прежде всего их высокой сорбционной способностью по отношению к ОтНп группировкам, в частности к воде [9, 10]. иВ состав цеолитов путем ионного обмена с использованием соответствующих аммиачных комплексов было введено небольшое количество (0, 1-0, 5 мас.%) ионов металлов Pt, Pd и Ru.

In order to increase the resources of branched C5-C6 hydrocarbons with high octane number, the direct involvement of straight-run gasoline in a catalytic low-temperature joint isomerization and disproportionation process has been studied. The corresponding routes of the main and side reactions of the process of direct involvement of straight-run gasoline on the Me-HZSM-5-SO4 2-/ZrO2 catalyst to determine their rate constants, taking into account the complex composition of the feedstock, were described. The paper presents the results of the conversion of straight-run gasoline (SRG) at 140-200 C on the catalyst Co-HZSM-5-SO4 2-/ZrO2. It has been established that the products of SRG conversion are mainly C5-C6 alkanes, the yield of which reaches 53-66%, containing up to 79-88% of the iso-components during the conversion of C8+ paraffins 36-77%. Kinetic studies have been carried out to directly involve of straight-run gasoline in low-temperature isomerizationdisproportionation conversion of straight-run gasoline, and show reaction routes. Calculations of reaction rate constants depending on the conversion condition were carried out using the MATLAB program (STATISTICA). From the found values of the reaction rate constants using the Arrhenius equation, the activation energies are calculated. A kinetic model of the process is proposed

Complexation in various platinum (II) conditions with …
Complexation in various platinum (II) conditions with various sulfur-oxygen and nitrogen-oxygen containing ligands was studied for the first time. Individual and mixed-ligand platinum complexes with ethylenediamine diacetate and mercaptoacetic acid were obtained. With the help of IR and other physical methods, the methods of coordination of these ligands with the central atom have been studied. When synthesizing complexes, the selected conditions are optimal for individuality and high yield. It was found that in the complex [Pt (EDDA)(NH3) 2] Cl2, ethylene diamine diadiazate is bidentate at the nitrogen atom in the cis-position. Under these conditions, the carboxyl group of the ligand is not involved in complexation. In the complex [Pt (SCH2COOH) 2 (NH3) 2] mercaptoacetic acid is coordinated monodentatno at the sulfur atom in trans positions. The carboxyl group of the ligand also does not participate in coordination. In the complex [Pt (EDDA)(SCH2COOH) 2] ethylene diamine diacetate in bidentate coordination form a fivemembered metal-chelate cycle in the cis-position, this leads to the forced monodentate cis coordination of mercaptoacetic acid. In all synthesized complexes, the carboxyl group of ligands are not involved in coordination.Study of the thermal behavior of synthesized complexes I-III showed that the decomposition of complexes depending on composition and structure occurs in different ways. The complexes are stable up to a maximum of 3150 C. Cleavage of ligands occurs in two stages. Complex II is stable up to 315 С, as evidenced by a clear area on the TG curve, and then the complex decomposes at high speed. The …

Using the pyrazine-modulated pentapyridyltetraamine ligand N2,N2′-(pyridine-2,6-diyl)bis(N6-(pyrazin-2-yl)pyridine-2,6-diamine) H4N9-2pz, three new mononuclear complexes [Cu(H4N9-2pz)](NO3)2∙(CH3CN) 1, [Cu(H4N9-2pz)]Cl2∙2(H2O) 2 and [Cu(H3N9-2pz)] (CH3COO)∙2.5(H2O) 3 have been synthesized, structurally characterized, and their bioactivity properties studied. In vitro analysis of complexes 1-3 revealed that they inhibited AChE and BChE more effectively than the widely available inhibitor tacrine (IC50: 123.58 ± 6.80 and 146.18 ± 7.91 µM). Additionally, their IC50 values for AChE and BChE ranged from 32.87 to 68.15 and 14.60 to 31.68 µM, respectively.

Due to the fact that nickel compounds are considered teratogenic and carcinogenic, it is necessary to develop effective methods for eliminating toxicity of Ni(II) ions in environment, thereby reducing the risk to human health. Taking into account the limited literature data on the potential of using avocado waste as Ni(II) ion sorbent, avocado seed utilisation can be a promising, low-cost, sustainable, and environmentally friendly direction in the development of novel sorbents for water purification. The aim of the research is to synthesise crosslinked avocado seed-based sorbents with ‘memory effect’ towards Ni(II) ions. Sorption capacity study is based on comparing crosslinked sorbents obtained by traditional method (sorbent-crosslinking-sorption of Ni(II) ions), as well as ‘memory effect’ creating method (sorbent-sorption of Ni(II) ions-crosslinking-desorption of Ni(II) ion-sorption of Ni(II) ions).

In the title compound, C16H13Cl4N3, the dihedral angle between the benzene rings of the dichlorophenyl and dimethylaniline groups is 50.85 (13)°. The central –N=N– unit shows an E configuration. In the crystal, molecules form parallel layers to the (100) plane by C—H···π and face-to-face π-π [centroid-to-centroid distances = 4.0538 (17) and 4.0537 (17) Å] interactions. These layers are connected by Van der Waals interactions to stabilize the crystal structure. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from Cl···H/H···Cl (36.4%), H···H (23.3%) and C···H/H···C (15.2%) contacts.

The rheology problems of non-Newtonian oil, accompanied by the physical phenomena of formation and destruction of coagulation structures and aggregates, significantly affecting the flow are considered and analyzed. Also are considered issues of hydrodynamic interaction of particles leading to the formation of disordered structures, which significantly change the rheological properties of non-Newtonian oil. It has been noted that the formation of coagulation structures depends on energy dissipation, viscosity, stress or shear rate, and the size of the particles forming the structure. With increasing asphalt-resin content in the oil, the probability of particle collision increases, increasing the rate of formation of various disordered structures up to a framework that nullifies the rate of oil flow. Applied problems of rheology, including dissolution kinetics of asphalt-resinous substances in aromatic hydrocar-bons and improving rheological properties of the oil, rheology of structured non-Newtonian oils in gas lift method of production, as well as possible ways to create new technologies for processing non-Newtonian oils were considered.

цеолитов основным направлением в превращении олефинов является их скелетная изомеризация [3]. Кроме того, исследование гидрирования 2-метилбутена-2 на натриевых формах различных цеолитов пока-зало, что начальная скорость реакции в зависимости от соотношения окислов кремния и алюминия проходит через максимум, приходя-щийся на цеолит типа У [1]. Для объяснения этого факта было вы-сказано предположение, что скорость гидрирования 2-метилбутена-2 в случае узкопористых цеолитов может лимитироваться внутридиффузионными процессами в порах катализаторов. Для проверки этого предположения нами исследовалась термодесорбция 2-метилбутена-2 с Па-форм цеолитов [4]. На основе найденных значений эффективных коэффициентов диффузии и факторов эффективности было показано, что внутридиффузионные влияния проявляются во всех случаях за исключением цеолита типа У.

The kinetic dependences of the initial reactions …
The kinetic dependences of the initial reactions occurring during oxidation of n-alkanes at low temperatures are considered. The kinetic data with the formation of, in particular, cyclic ethers are estimated. The model used allows predicting the experimental data obtained in the static reactor. Improved data on the selectivity of cyclic ethers are obtained in comparison with previous models. It has been shown that under given initial conditions, during the catalytic oxidation of n-alkanes, incomplete oxidation of nalkanes occurs. Oxidation reactions were carried out at relatively low temperatures using metal-polymer systems including Mn and Ni. During the catalytic oxidation of saturated hydrocarbons with oxygen, alcohols, ketones and acids are predominantly formed. Organic acids occur in isolated cases; the bulk of the n-alkane remains unchanged in the reaction. Practically important dependences of the catalytic oxidation of n-alkanes at low temperatures have been constructed. The influence on the initial reaction rate of the following parameters was taken into account: temperature, oxygen consumption, the mass of catalyst, initial n-alkane concentration, n-alkane concentration as a function of normalized time.

A new ligand N-nicotinoyl-N′-(3,5-ditertbuthyl-2-hydroxy)benzylidene hidrazine (H2L) was synthesized and a complex [VO(L)CH3O·CH3OH] with this ligand was obtained and their structures investigated by X-ray crystallography. It was found that the methanol molecule in the complex is easily exchanged for a pyridine molecule. The effects of H2L and [VO(L)CH3O CH3OH] complexes against AChE, BChE and α-glucosidase enzymes were investigated using Ellman and Tao methods and the results were calculated as IC50 and Ki. Both compounds demonstrated effective inhibition of all three enzymes, with varying degrees of potency. For AChE, H2L exhibited the lowest IC50 value (8.45 μM, r2 = 0.993) and a Ki of 5.53 ± 0.73 μM, outperforming both its vanadium complex (IC50 = 10.61 μM, Ki = 7.38 ± 1.14 μM) and the reference drug tacrine (IC50 = 13.75 μM, Ki = 11.90 ± 1.01 μM …

The research work is devoted to enhancing the processing efficiency of light pyrolysis rezin for ethylene production and developing a mathematical model of this process. The process is aimed at increasing the yield of benzene by dealkylation of benzene-alkyl derivatives in the system using a toluene-based aluminum complex catalyst. Calculations were performed using the OptimMe and OriginLab software packages. By studying the effect of various factors (the amount of benzene at the beginning, temperature, the amount of catalyst, the duration of the process, etc.), the optimal temperature regime of the process, the composition and amount of the catalyst, and the duration of the process corresponding to the maximum yield of benzene were selected. Using these results, a multifactorial mathematical model of the process was developed, the adequacy of the model was determined by the Fisher's criterion, and the regression coefficients were evaluated by the Student's criterion. The obtained regression enables us to estimate the yield of benzene based on any concentration of the catalyst and the temperature conditions of the process (ranging from 0 to 80 C). and thus can be used to minimize the total costs of implementing the process. Calculations indicate that the maximum yield of benzene occurs at a temperature of 80 C, with a catalyst concentration of 2.5%, and a process duration of 240 minutes.

The homogeneity boundaries of liquid two-component solutions of sulfur with copper, lead of three component Cu-Pb-S melts are determined and approximated by solving the thermodynamic equations of heterogeneous P-T-x phase equilibrium using MGA. Experimental data were used for state diagrams of boundary systems Copper-Sulfur Lead-Sulfur and the quasi-binary section Copper (I) Sulfide -Lead (II) Sulfide. For the first time, critical temperatures (Tcr) and pressure (Pcr) were determined for the immiscibility regions of sulfur-rich liquid alloys, which have high values: Pcr = 170 ÷ 510 atm and Tcr = 1520 ÷ 1880 K. Lead (II) sulfide crystallization surfaces p-type PbS1 + x and n-type conductivity Pb1 + xS, as well as the saturated vapor pressure of diatomic sulfur molecules above the liquidus surface of lead sulfide of variable composition were calculated and modeled. All functional relationships Temperature (T …

Сложные халькогениды на основе меди, благодаря разнообразным физическим и физико-химическим свойствам, экологической безопасности и доступности, относятся к числу важнейших функциональных материалов современной техники и технологии. Разработка новых подобных материалов и улучшение прикладных характеристик известных соединений в значительной степени связана с применением подходов, основанных на принципах физико-химического анализа и, в частности, взаимосвязи «состав-структура-свойство». В данном обзоре обобщены имеющиеся данные по фазовым равновесиям в тройных системах Cu-Tl(BIV, BV)-X (BIVSi, Ge, Sn; BV-As, Sb, Bi; X-S, Se, Te) и термодинамическим свойствам их промежуточных фаз. Рассмотрены также подобные данные для более сложных систем, образующих твердые растворы различных типов замещения на основе известных тройных халькогенидов меди. Значительная часть представленных комплексов взаимосогласованных данных по фазовым равновесиям и термодинамическим свойствам рассмотренных систем получена нашей группой в течение последних 10-15 лет. Несмотря на то, что эти данные охватывают лишь малую часть вышеуказанных систем, они открывают большие возможности для манипуляции состава и структуры, включая стратегию энтропийной инженерии. Авторы считают исключительно важным дальнейшее развитие фундаментальных исследований по фазовым равновесиям и термодинамическим свойствам сложных халькогенидов меди и широкое использование …

Одним из наиболее перспективных энергоносителей, полученных с использованием солнечной энергии, является водород. В настоящее время использование полупроводниковых материалов для преобразования солнечной энергии путем электролиза воды в запасаемый водород является актуальным направлением исследований [1-2]. Поэтому, с этой целью были разработаны и испытаны многие типы фотоэлектродов на основе диоксида титана (TiO2)[3-6]. Среди таких фотоэлектродов гематит (Fe2O3) также продолжает вызывать большой интерес, поскольку он удовлетворяет ряду требований к полупроводникам, идеально подходящим для фотоэлектролиза воды. TiO2 и Fe2O3 являются полупроводниками n-типа, обладающими высокой стабильностью в качестве фотоанодов, неагрессивными по отношению к окружающей среде, низкой стоимостью [7-8]. Гематит представляет собой полупроводник с оптической шириной запрещенной зоны 2, 1 эВ и положением края валентной зоны, подходящим для окисления воды [9]. Фотоаноды на основе Fe2O3 и TiO2 могут быть получены разными методами: золь-гель, пиролиз, химическое осаждение из паровой фазы, осаждение атомных слоев, электроосаждение и др.[10-12]. Цель работы состоит в изучении фотоэлектрохимических свойств гетероструктуры Fe2O3/TiO2. Для этого, в первую очередь, была синтезирована гетероструктура Fe2O3/TiO2. Осаждение железа осуществлялась на поверхность никелевого электрода. Далее с помощью термической обработки на воздухе при температуре 500 С …

Ископаемое топливо (уголь, нефть и газ) являются основным источником энергии для удовлетворения глобальной потребности экономики в ней, однако эти запасы уменьшаются по мере роста спроса на энергию, которые продолжают расти c каждым годом. Более того, их неизбирательное использование явно связано с увеличением выбросов диоксида углерода в атмосферу, что является основной причиной парникового эффекта и изменения климата. Водород-химический продукт, который можно использовать в качестве топлива и производится из возобновляемых источников энергии, таких как солнечная и в результате разложения воды при ее электролизе. Основное преимущество водорода перед электричеством заключается в том, что водород является химическим энергоносителем, который можно хранить и транспортировать как, например, нефть или …
