Abstract

1321981 Primary amines by hydrogenation of nitriles N WADDLETON (Messrs Anderson Luedeka Fitch Even & Tabin) 29 June 1970 [1 April 1969] 16931/69 Heading C2C A process for the preparation of a primary amine comprises hydrogenating a nitrile under superatmospheric pressure in the presence of an aqueous ammonia solution having a concentration of at least 0À05% by weight. Preferably the reaction is carried out at a temperature of from 125‹ to 145‹ C. with the partial pressure of ammonia being at least 150 p.s.i. at the reaction temperature.
