(57) [Summary] [Structure] A Ru / Pd mixture containing a noble metal in a total amount of 0.05 to 5% by weight, preferably 0.1 to 4% by weight, particularly preferably 0.1 to 3% by weight. In the case of both metals in a weight ratio of 1: 9 to 9: 1, preferably 2: 8 to 8: 2, particularly preferably 3: 7 to 7: 3, provided that all percentages are based on the total weight of the catalyst. Ruthenium, palladium, or a mixture of both, based on Nb niobate. 2 O 5 · nH 2 O, the catalyst containing on a support comprising a tantalate Ta 2 O 5 · nH 2 O or a mixture of both. [Effect] (Substituted) cyclohexylamine and (substituted) dicyclohexylamine can be produced by catalytically hydrogenating (substituted) aniline using the above catalyst. |
