Abstract

Aromatic compounds in which at least one amino group is bonded to an aromatic nucleus are catalytically hydrogenated in the liquid phase by a process in which the catalyst consists essentially of ruthenium and, optionally at least one metal of subgroup I, VII or VIII in an amount of from 0.01 to 30% by weight, based on the total weight of the catalyst, applied to a carrier which has a mean pore diameter of at least 0.1 .mu.m and a surface area of not more than 15 m.sup.2 /g.
