原始语种摘要: A comparative study of the kinetic regularities of the reduction of aromatic nitro-compounds of a various structure (nitrobenzene, nitrophenols, nitroanilines and p-nitrodiethyl aniline) on Pd and Pd-Pt catalysts deposited on various carries is carried out. Comparative hydrogenation of nitro compounds and nitrocompounds in a mixture with the corresponding amines (the reaction products) was studied. The presence of the hydrogenation products (amines) having a stronger propensity to adsorption on the catalyst surface than the starting hydrogenated compounds may cause decrease of the process speed and amount of absorbed hydrogen. The ratio of the adsorption coefficients confirmed it. It was revealed that at comparative hydrogenation of nitro compounds of various structure in ethanol and...
