Abstract: The invention relates to a method for simultaneous preparation of 6- aminocapronitrile and hexamethylene diamine from adipodinitrile, comprising the following steps: a) hydrogenating adipodinitrile in the presence of a catalyst containing an element of the eight subgroup as catalytically active component to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers; b) separating by distillation hexamethylene diamine from the mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers and c1) separating by distillation 6-aminocapronitrile and subsequently d1) separating by distillation adipodinitrile or c2) simultaneously separating by distillation 6- aminocapronitrile and adipodinitrile into separate fractions. The method is characterized in that the temperature of the bottom in steps d1) or c2) is below 185 ~ C.

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.
