Palladium catalyst and its use in the preparation of a mixture of optionally substituted cyclohexylamine and optionally substituted dicyclohexylamine

摘要

A Pd catalyst in which an &agr;- or &ggr;-Al.sub.2 O.sub.3 as support is first treated with at least one compound of the rare earth metals and with at least one compound of manganese and then with at least one palladium compound is suitable for the preparation of a mixture of optionally substituted cyclohexylamine and optionally substituted dicyclohexylamine by hydrogenation of a correspondingly substituted aniline.
