For the continuous preparation of a mixture of amino-methyl-cyclohexanes and diamino-methyl-cyclohexanes by catalytic hydrogenation of diamino-toluenes with hydrogen at temperatures of from 150 to 260°C and an H2 pressure of from 20 to 500 bar, use is made of a fixed-bed catalyst comprising ruthenium on an Al2O3 support treated with compounds of rare earth metals, of manganese and alkali metal hydroxides or alkaline earth metal hydroxides.

Pour la préparation en continu d'un mélange d'aminométhylcyclohexanes et de diaminométhylcyclohexanes par hydrogénation catalytique de diaminotoluènes à l'aide d'hydrogène à des températures de 150 à 260 °C et à une pression de 20 à 500 bars de H2, on utilise un catalyseur à lit fixe, renfermant du ruthénium sur un support de Al2O3 traité par des composés de métaux des terres rares, d'hydroxydes de manganèse et de métaux alcalins ou d'hydroxydes de métaux alcalino-terreux.
