Abstract

The influence of the hydrogen partial pressure varied in the interval (4.3–100) × 103 Pa on the kinetics of liquid-phase catalytic hydrogenation of aromatic mononitro compounds in the presence of platinum and iridium supported on activated carbon in various percent ratios (Pt/C-2.5% and Ir/C-5%) was studied for 3,4-dichloronitrobenzene as example. A decrease in the hydrogen partial pressure leads to a significant decrease in the rate of the nitro compound consumption and in the yield of the intermediate arylhydroxylamine. A kinetic mechanism of hydrogenation of the nitro compound, satisfactorily describing the experimental data, was suggested.
