PROCESS FOR THE PRODUCTION OF DI-(4-AMINOCYCLOHEXYL)-METHANE CONTAINING 15 TO 25% BY WEIGHT OF THE TRANS-TRANS ISOMER |
| 摘要 |
Di-(4-aminocyclohexyl)-methane containing 15 to 25% by weight of the traps-traps 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 Al2 0 3 support which has been treated with compounds of rare earth metals and manganese.
