摘要： A method for catalytic hydrogenation of adipodinitrile into hexamethylene diamine at a high temperature and high pressure in the presence of catalysts based on elementary iron as a catalytically active constituent and ammonia as a solvent. The invention is characterized in that a) adipodinitrile is hydrogenated at temperatures ranging from 70 to 220 °C and at pressures of 100-400 bars in the presence of catalysts based on elementary iron and ammonia as a solvent to obtain a mixture containing adipodinitrile, 6-aminocapronitrile, hexamethylene diamine and high boilers until the sum of the 6-aminocapronitrile and adipodinitrile concentrations amount to 1-50 wt. % in relation to the ammonia-free hydrogenation mixture; b) ammonia is separated from the hydrogenation product; c) hexamethylene diamine is separated from the remaining mixture; d) 6-aminocapronitrile and adipodinitrile are separated individually or jointly from high boilers and e) 6-aminocapronitrile, adipodinitrile or the mixtures thereof are returned to step a).
