PURPOSE: Provided is a hydrogenation process for the preparation of aromatic amino compounds containing directly on the aryl ring or in a side chain one or more entities that may also undergo hydrogenation, such as carbon multiple bonds, nitrile groups, imino groups or carbonyl groups. CONSTITUTION: Provided is a process for the preparation of substituted aromatic amino compounds containing at least one carbon-carbon, carbon-nitrogen or carbon-oxygen multiple bond on the aromatic moiety or in a side chain, by means of catalytic hydrogenation of corresponding substituted aromatic nitro compounds in the presence of a modified noble metal catalyst, wherein rhodium, ruthenium, iridium, platinum or palladium modified with an inorganic or organic phosphorus compound having an oxidation state of less than 5 is used as the noble metal catalyst.
