Ruthenium catalyst, process for its preparation and process for the preparation of a mixture of cyclohexylamine and dicyclohexylamine using the ruthenium catalyst

摘要

Substituted or unsubstituted cyclohexylamine and substituted or substituted dicyclohexylamine can be produced by catalytic hydrogenation of substituted or unsubstituted aniline, for which a catalyst is used containing ruthenium and palladium which are attached to a support and which catalyst furthermore contains a basic alkali metal compound. The catalyst contains the noble metals in a total amount of 0. 05 to 5% by weight and in a weight ratio of ruthenium to palladium such as 1:9-9:1. The basic alkali metal compound is present in an amount of 0. 1-10% by weight. All percentages are based on the total weight of the catalyst.
