Abstract: The invention relates to a method for removing, by distillation, 6-aminocapronitrile from mixtures that contain 6-aminocapronitrile, adipodinitrile and hexamethylenediamine, by a) removing the hexamethylenediamine from the mixture while obtaining a mixture (I) that has a hexamethylenediamine content of less than 1 wt. -%, b) removing completely or partially the 6-aminocapronitrile from mixture (I) while obtaining a mixture (II) whose content in substances that have a higher boiling point as 6-aminocapronitrile under distillation conditions and that cannot be formed by dimerization reactions when 6-aminocapronitrile is thermally treated is less than 1 wt. -%, and c) completely or partially removing from mixture (II) the hexamethylenediamine that might be present while obtaining a mixture (IV) whose hexamethylenediamine content is higher than that of mixture (II), and a mixture (V) whose hexamethylenediamine content is lower than that of mixture (II).

Abstract: 6-Aminocapronitrile (6-ACN) is separated from its mixtures with adiponitrile and hexamethylenediamine (HMDA) by a 3-step distillative process. Distillative separation of 6-aminocapronitrile (6-ACN) from its mixtures with adiponitrile and hexamethylenediamine (HMDA) comprises: (a) separating out HMDA to give a mixture (M-I) of HMDA content below 1 wt.%; (b) partly or completely separating out 6-ACN from (M-I) to give a mixture (M-II) containing less than 1 wt.% of materials which are higher boiling than 6-ACN under distillation conditions and which cannot be formed by heat dimerization of 6-ACN; and (c) partly or completely separating out any existing HMDA from (M-II) to give a mixture (M-III) with a HMDA content higher than (M-II) and a mixture (M-IV) with a HMDA content lower than (M-II).
