| titleOfInvention | Improved method for simultaneous production of 6-aminocapronitrile and hexamethylenediamine |
| abstract | (57) [Summary]nA process for the simultaneous production of 6-aminocapronitrile and hexamethylenediamine starting from adiponitrile, comprising the following steps: a) in the presence of a catalyst comprising a Group VIII transition metal element as catalytically active component Hydrogenation of adiponitrile to obtain a mixture containing 6-aminocapronitrile, hexamethylenediamine, adiponitrile and high-boiling substances, b) converting 6-aminocapronitrile, hexamethylenediamine, adiponitrile and high-boiling substances to Distilling hexamethylenediamine from the mixture containing the mixture, and any of the following steps c1) and d1) or c2); c1) distilling off 6-aminocapronitrile, and then d1) distilling adiponitrile Step c2) 6-aminonit Process is a further fraction was simultaneously distilled off as Le and adiponitrile, although the bottom temperature in step d1) or c2) is less than 185 ° C.. |
