Abstract (en)

[origin: DE19754571A1] According to the inventive method for producing mixtures of optionally substituted cyclohexylamine and optionally substituted dicyclohexlamine in variable amounts by hydrogenating optionally substituted aniline using a catalyst, at a high temperature and at a high H2 pressure, Ru/Pd catalysts on supports are used. Said catalysts are characterised in that they do not contain any halogen or sulphur compounds.
