Abstract
Abstract Optionally substituted cyclohexylamine and optionally substituted dicyclohexylamine can be obtained by catalytic hydrogenation of optionally substituted aniline, a catalyst being used which contains ruthenium, palladium or a mixture of both metals which have been applied to a support of niobic acid or tantalic acid or a mixture of the two. The catalyst contains the noble (metal)s in a total quantity of 0.05-5% by weight, relative to the total weight of the catalyst. In the case of both noble metals being used, their mutual weight ratio is 1:9-9:1.
