Title (EN) METHOD FOR PREPARING DIAMINO-DICYCLOHEXYL METHANE
(FR) PROCÉDÉ POUR PRÉPARER DU MÉTHANE DIAMINO-DICYCLOHEXYL
(ZH) 二氨基二环己基甲烷的制备方法
Abstract: front page image
(EN)A method for preparing diamino-dicyclohexyl methane (H12MDA) by catalytic hydrogenation of diamino-diphenyl methane (MDA). In the process, 4,4'-MDA is firstly used as starting material to prepare 4,4'-H12MDA by catalytic hydrogenation. When the activity of the catalyst decrease, the deactivated catalyst is activated online by switching the feed as the mixture of 2,4'-MDA and 4,4'-MDA.
(FR)L'invention concerne un procédé pour préparer du méthane diamino-dicyclohexyl (H12MDA) par hydrogénation catalytique de méthane diamino-diphényl (MDA). Au cours du processus, 4,4'-MDA est d'abord utilisé en tant que produit de départ pour préparer 4,4'-H12MDA par hydrogénation catalytique. Lorsque l'activité du catalyseur baisse, le catalyseur désactivé est activé en ligne par commutation de l'alimentation en tant que mélange de 2,4'-MDA et 4,4'-MDA.
(ZH)一种二氨基二苯基甲垸(MDA)加氢催化制备二氨基二环己基甲垸(H12MDA)的方法。该工艺是首先以4,4'-MDA为原料加氢催化制备4,4'-H12MDA,当催化剂活性下降时,通过切换进料为2,4'-MDA和4,4'-MDA的混合物,使失活的催化剂在线活化。
