RUTHENIUM CATALYST, PROCESS FOR ITS PREPARATION AND METHOD FOR PRODUCING A MIXTURE OF CYCLOHEXYLAMINE AND DICYCLOHEXYLAMINE USING THE RUTHENIUM CATALYST

摘要

1. Process for the preparation of a mixture of substituted or unsubstituted cyclohexylamine and substituted or unsubstituted dicyclohexylamine by hydrogenation of substituted or unsubstituted aniline in the presence of a ruthenium catalyst, characterized in that the catalyst used is one containing ruthenium and palladium on a support containing the noble metals in a total amount of 0.05-5% by weight and a weight ratio of ruthenium to palladium such as 1:9-9:1 and furthermore containing 0.1-10% by weight of an alkaline alkali metal compound, all percentages being based on the total weight of the catalyst, and the hydrogenation is carried out at 150-220 degrees C and at a pressure of 0.5-10 bar, preferably 0.5-4 bar, particularly preferably 0.7-2 bar.
