It was experimentally established that the amounts of hydrogen absorbed from gase-ous phase at the hydrogenation of nitrobenzene and nitrosobenzene on skeletal nickel in aqueous 2-propanol do not correspond to the stoichiometry of the reaction. Acetic acid or sodium hydroxide additions into the aqueous solutions of 2-propanol act differently on the rate of the nitro-, nitroso- and azoxybenzene hydrogenation. During the reaction the reversi-ble or irreversible oxidation of the catalyst surface can take place. The adsorption of aniline does not take place on oxidized catalyst surface.

Key words: nitrobenzene, nitrosobenzene, azoxybenzene, aniline, skeletal nickel, adsorption, hydrogenation rate, 2-propanol aqueous solutions, acetic acid, sodium hydroxide
