Zusammenfassung: | PURPOSE: To prepare (substd.) cyclohexylamine and (substd.) dicyclohexylamine by catalytic hydrogenation of (substd.) aniline with use of a catalyst. CONSTITUTION: A catalyst contains ruthenium, palladium or mixture of both on a carrier comprising niobic acid Nb2 O5 .nH2 O, tantalic acid Ta2 O5 .nH2 O or a mixture of both in the total amount of 0.05-5 wt.%, pref. 0.1-4 wt.%, particularly pref. 0.1-3 wt.%, and at a weight ratio between Ru and Pd of 1:9-9:1, pref. 2:8-8:2, particularly pref. 3:7-7:3 in the case of the use of Ru/Pd mixture, relative to the total weight of the catalyst. |
