摘要：
Di-(4-aminocyclohexyl)-methane containing 15 to 25% by weight of the trans-trans isomer can be obtained by the catalytic hydrogenation of di-(4-aminophenyl)-methane at elevated temperature and elevated hydrogen pressure in the presence of a ruthenium-containing supported catalyst containing 0.05 to 5% by weight ruthenium on an Al.sub.2 O.sub.3 support which has been treated with compounds of rare earth metals and manganese.
