| titleOfInvention | Process for catalytically hydrogenating adiponitrile to hexamethylenediamine at elevated temperature and pressure |
| abstract | "PROCESS FOR CATALYTIC HYDROGENATION FROM ADIPONITRILLA TO HEXAMETHYLENODIAMINE IN HIGH TEMPERATURE AND PRESSURE". The invention relates to a process for the catalytic hydrogenation of adiponitrile to hexamethylenediamine at an elevated temperature and at a high pressure in the presence of elemental iron-based catalysts such as the catalytic component and ammonia as a solvent. The process is characterized by the fact that a) adiponitrile is hydrogenated at temperatures of 70 to 220 ° C and at pressures of 100 to 400 bar in the presence of catalysts based on elementary iron such as the catalytic component and ammonia as a solvent to produce a mixture which contains adiponitrile, 6-aminocaponitrile, hexamethylenediamine and high boiling compounds until the sum of the concentration of 6-aminocaponitrile and adiponitrile is 1 to 50% by weight with respect to the ammonia-free hydrogenation mixture; b) ammonia is separated from the hydrogenation discharge; c) hexamethylenediamine is separated from the remaining mixture; d) 6-aminocaponitrile and adiponitrile are separated from the high boiling compounds together or separately and e) 6-aminocaponitrile, adiponitrile or mixtures thereof are returned to step a). |
