Molecular organization of reactants in the kinetics and catalysis of liquid phase reactions: X. Synergism in the combined catalysis of urethane formation by organotin compounds and tertiary amines
Kinetics and Catalysis - Tập 41 - Trang 355-358
D. N. Tarasov, R. P. Tiger, Yu. N. Chirkov, S. G. Entelis, J. -J. Tondeur
The kinetics of the reaction of m-Cl-phenyl isocyanate with n-butanol in heptane catalyzed by tin tributylacetate and diazobicyclooctane is studied. The phenomenon of synergism in the catalysis of urethane formation is quantitatively described by the simulation of kinetics using the data on the equilibrium constants of association of the alcohol in the system and modern concepts on the reaction me... hiện toàn bộ
Mechanism of phthalic anhydride formation in the oxidation of n-pentane on a vanadium-phosphorus oxide catalyst
Kinetics and Catalysis - - 2006
V. A. Zazhigalov, E. V. Cheburakova, M. Gansior, J. Stoch
The reaction paths of product formation in the partial oxidation of n-pentane on vanadium-phosphorus oxide (VPO) and VPO-Bi catalysts are considered. The condensed products of n-pentane oxidation were analyzed by chromatography-mass spectrometry, and the presence of C4 rather than C5 unsaturated hydrocarbons was detected. It was found that the concentration of phthalic anhydride in the products in... hiện toàn bộ
Effect of the acidity and chemical nature of the protonating agent on the rate of acetylene reduction catalyzed by the nitrogenase active site isolated from the enzyme
Kinetics and Catalysis - Tập 53 - Trang 306-312 - 2012
T. A. Bazhenova, N. V. Kovaleva, G. N. Petrova
The effect of the acidity (pK a) of the source of protons on the rate and selectivity of acetylene reduction has been investigated in order to elucidate the mechanism of protonation of substrate molecules coordinated to the reduced FeMoco cluster. A number of compounds whose pK a in DMF varies between 6 and 20 have been examined as protonating agents. The rate of the reaction is almost independent... hiện toàn bộ
Kinetic parameters of the cyclization and decyclization reactions of nitrogen- and oxygen-containing radicals
Kinetics and Catalysis - Tập 46 - Trang 1-9 - 2005
T. G. Denisova, E. T. Denisov
The intersecting parabolas model is used to analyze experimental data for the following radical cyclization and decyclization reactions: RCH=CH(CH2) n N·R1 → cyclo-[NR1CH(CH2) n ]C·HR, R(CH2)2OOCH2C·HR → cyclo-[RCHOCH2] + RCH2CH2O·, cyclo-[(CH2) n OOCHC· HR] → cyclo-[RCHOCH](CH2) n O·, cyclo-[(CH2) n OC·RO] → RC(O)O(CH2) n − 1C·H2, and cyclo-[(CH2) n CHO·] → CH(O)(CH2) n − 1C·H2. The activation en... hiện toàn bộ
Synthesis of nanosized thin-film bimetallic catalysts based on mesoporous TiO2 for microstructured reactors

Formation of the Ni–CrOx/MgO and Ni/MgO Catalysts for Carbon Dioxide Reforming of Methane
Kinetics and Catalysis - - 2001
V. Yu. Bychkov, V. N. Korchak, O. V. Krylov, O. S. Morozova, T. I. Khomenko
Temperature-programmed reduction by hydrogen, temperature-programmed desorption of O2, local X-ray spectral analysis, and scanning electron microscopy are used to study redox processes occurring on the Ni–Cr2O3/MgO and Ni/MgO catalysts for carbon dioxide reforming of methane. The reduction of Ni/MgO leads to the formation of nickel clusters distributed over the surface of MgO. During the reduction... hiện toàn bộ
A comparative study of Ir/Ga2O3, Pt/Ga2O3, and Ru/Ga2O3 catalysts in selective hydrogenation of crotonaldehyde
Kinetics and Catalysis - Tập 49 - Trang 574-580 - 2008
E. Gebauer-Henke, J. Farbotko, R. Touroude, J. Rynkowski
Catalytic performance of gallia-supported iridium catalysts in the reaction of selective hydrogenation of crotonaldehyde in the gas phase was studied and compared to that of platinum and ruthenium catalysts. The best catalytic properties in terms of the selectivity to crotyl alcohol are shown by 5 wt % Pt/α-Ga2O3 and 5 wt % Ir/α-Ga2O3 catalysts prepared from nonchlorine precursors: Pt(acac)2 and I... hiện toàn bộ
Effect of water on the kinetics of the catalytic reaction between benzoic acid and aniline
Kinetics and Catalysis - Tập 48 - Trang 632-635 - 2007
L. Ya. Shteinberg, S. A. Kondratov, S. M. Shein, V. V. Marshalova
Water forming in benzanilide synthesis from benzoic acid and aniline catalyzed by titanium tetrabutoxide does not influence the activity of the catalyst. The role of mass transfer processes associated with water removal from the system is revealed. The reversible deactivation of titanium tetrabutoxide by water occurs in the absence of vigorous water boiling and distillation. The stability of titan... hiện toàn bộ
Properties of surface compounds in methanol conversion on γ-Al2O3: Data of in situ IR spectroscopy
Kinetics and Catalysis - - 2009

Analysis and Simulation of the Dynamics of a Catalyzed Model Reaction: CO Oxidation on Zeolite Supported Palladium
Kinetics and Catalysis - Tập 44 - Trang 183-197 - 2003
N. I. Jaeger, N. V. Peskov, M. M. Slinko
The particle size effect on the oscillatory behavior during CO oxidation over zeolite-supported Pd catalysts is simulated with the help of a deterministic point model and a stochastic mesoscopic model. The point model is developed on the basis of the well-known Sales–Turner–Maple model, which is modified to consider the slow processes of oxidation and reduction of the Pd bulk as well as the effect... hiện toàn bộ
