Abstract

A process for the preparation of p-amino-diphenylamine which comprises catalytically hydrogenating p- nitroso-diphenyl hydroxylamine in the presence of an organic solvent, which is aniline or the amine of a benzene homologue containing from 7 to 12 carbon atoms of mono- or di-alkylamino derivatives thereof containing from 1 to 6 carbon atoms in the N-alkyl group(s), and one or more of the metals ruthenium, rhodium, palladium osmium, iridium and platinum or the sulphidic compounds thereof as a catalyst at a temperature of from 20 to 200 DEG C, is disclosed. Inter alia, the present invention is distinguished by the choice of solvent which results in, in particular, good selectivity, high conversion and short reaction times.
