Hydrogen-free homogeneous catalytic reduction of olefins in aqueous solutions
(American Chemical Society, 2008-07)
Herein we report a study involving the homogeneous catalytic reduction ofunsaturated substrates in aqueous solutions or water-organic solvent mixtures. The reduction of olefins has been carried out in the presence of ...
Adsorptive square-wave voltammetry of quasi-reversible electrode processes with a coupled catalytic chemical reaction
(Springer, 2016-12-09)
There are several strategies for enhancing the sensitivity of electroanalytical methods. Usually, those strategies are based on the selection of the voltammetric technique, the inclusion of an accumulation step, and the ...
Environmental topology and water availability modulates the catalytic activity of beta-Galactosidase entrapped in a nanosporous silicate matrix
(Nature Publishing Group, 2016-11-04)
In the present work we studied the catalytic activity of E. coli β-Gal confined in a nanoporous silicate matrix (Eβ-Gal) at different times after the beginning of the sol-gel polymerization process. Enzyme kinetic experiments ...
Estimation of effectiveness factor for arbitrary particle shape and non-linear kinetics
(American Chemical Society, 2008-09-25)
A one-dimensional model, called generalized cylinder (GC), is employed to analyze the diffusion-reaction problem in catalytic pellets of different shapes and nonlinear kinetics. The fitting parameter (ó) of the GC model ...
Interpretation onf the kinetic mechanism and the structural sensitivity of the catalitic CO-NO reaction
(2004)
The experimental results for the superficial reduction reaction of NO by CO over a number of different particle size rhodium catalysts supported on silica have been analysed quantitatively by the kinetic mechanism of Peden ...
Kinetic Modelling of the catalytic oxidation of 2-(methylmercapto)-benzothiazole under mild conditions
(Elsevier Science, 2017-07)
2-(Methylmercapto)-benzothiazole oxidation was performed over Copper modified zeolites. The microporous materials were synthesized by the hydrothermal crystallization method and later modified with metal incorporation by ...
A kinetic study of the 1,3-dipolar cycloaddition reaction between N-p-methoxybenzyliden-α-phenylglycine methyl ester and nitrosobenzene
(1997)
The kinetics of the reaction between N-p-methoxybenzyliden-cc-phenylglycine methyl ester and nitrosobenzene, using benzene as the solvent and both acetic and chloroacetic acid as catalysts, was studied by means of UV-VIS ...
Catalytic epoxidation of cyclohexene using Molybdenum complexes
