Abstract: In the present invention, there is disclosed a hydrogenation process of alpha-, omega-dinitriles in the presence of a catalyst, said process being characterized in that as a catalyst, there is used a mixture containing the following components: (a) iron or iron-based compound or mixtures thereof, (b) 0.001 to 0.3 percent by weight of a promoter based on 2, 3, 4 or 5 elements being selected from the group consisting of aluminum, silicon, zirconium, titanium and vanadium,(c) from 0 to 0.3 percent by weight based on the component (a) weight of a compound based on an alkali and/or alkaline earth metal, and also (d) from 0.001 to 1 percent by weight based on the component (a) weight of manganese. The above-specified mixture for the catalysis is obtained by reduction and optional passivation of magnetite, or by precipitation of substances that provide on carrier materials or without their presence the above components (a), (b), (d) and optionally (c), or by impregnating a carrier with a solution of the components (a), (b), (d) and optionally (c), or spraying the components (a), (b), (d) and optionally (c) to a carrier.

Abstract: The invention relates to a method for simultaneous production of 6-aminocapronitrile and hexamethylenediamine from adipodinitrile, comprising the following steps: a) hydrogenating adipodinitrile in the presence of a catalyst containing an element of the VIII subgroup thereby obtaining a mixture containing 6-aminocapronitrile, hexamethylenediamine, adipodinitrile and high boilers; b) distillative separation of hexamethylenediamine from the mixture containing 6-aminocapronitrile, hexamethylenediamine, adipodinitrile and high boilers or c1) distillative separating 6-aminocapronitrile and subsequently d1) distillative separation of adipodinitrile or c2) simultaneous distillative separation of 6-aminocapronitrile and adipodinitrile into separate fractions. The invention is characterized in that temperatures in the bottoms of the column in steps d1) or c2) are under 185 DEG C. The adipodinitrile thus obtained contains less impurities than for instance 1-amino-2-cyanocyclopentenes.
