摘要/Abstract

摘要： The kinetics of catalytic hydrogenation of ortho-nitrochlorobenzene to 2,2’-dichloroazoxybenzene on platinum/carbon catalyst is investigated in a slurryreactor with the temperature range of 313--343 K, and orthochloroaniline is formed as a byproduct. Models based on Rideal-Eley and Langmuir-Hinshelwoodmechanism have been proposed based on the rate data and the kinetic regime. The former model can be used to fit the experimental data better. Reaction controlling steps are physical adsorption of hydrogen and adsorbed ortho-nitrochlorobenzene reacted on the surface of catalyst.
