Title (DE) ISOMERISIERUNG VON MDACH
(EN) ISOMERIZATION OF MDACH
(FR) ISOMÉRISATION DE MDACH
Abstract:
(DE) Verfahren zur Isomerisierung eines Ausgangsgemisches, welches 2,4-Diamino-1-methylcyclo- hexan, kurz 2,4-MDACH, 2,6-Diamino-1-methylcyclohexan, kurz 2,6-MDACH, oder deren Gemische enthält, dadurch gekennzeichnet, dass die Isomerisierung in Gegenwart eines Trägerkatalysators mit Zirkondioxid als Träger und Ruthenium als aktivem Metall durchgeführt wird.
(EN) The invention relates to a process for the isomerization of a starter mixture, comprising 2,4-diamino-1-methyl-cyclo-hexane, in short 2,4-MDACH, 2,6-diamino-1-methylcyclohexane, in short 2,6-MDACH, or their mixtures, characterized in that the isomerization is carried out in the presence of a support catalyst with zirconium dioxide as a support and ruthenium as an active metal.
(FR) Procédé d'isomérisation d'un mélange de départ qui contient du 2,4-diamino-1-méthylcyclo-hexane, abrégé 2,4-MDACH dans sa forme courte, du 2,6-diamino-1-méthylcyclohexane, abrégé 2,6-MDACH, ou des mélanges de ceux-ci, caractérisé en ce que l'isomérisation est réalisée en présence d'un catalyseur supporté comprenant du dioxyde de zirconium comme support et du ruthénium comme métal actif.
