Beschreibung
Zusammenfassung:	In the preparation of a mixture of cyclohexylamine and dicyclohexylamine of formulae (I) and (II) by catalytic hydrogenation of aniline of formula (II) at 140-240 degrees C and a hydrogen (H2) pressure of 10-400 bar, the catalyst is a moulding, free from carrier, obtained by reduction of a moulding of compressed powders of cobalt (Co), manganese (Mn) and alkaline earth metal (hydr)oxides and (hydr)oxides of sub-group V and/or VI elements; in which R1, R2 = H, 1-4C alkyl or 1-4C alkoxy.
