Abstract

1397729 Adiponitrile IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Sept 1972 [11 Oct 1971] 47189/71 Heading C2C [Also in Division B1] Adiponitrile is made by heating adipic acid with ammonia in the vapour phase in the presence of a catalyst comprising phosphoric acid or a phosphate and a mineral which is an aluminium silicate or an aluminosilicate. A molar ratio of ammonia to adipic acid of 4 : 1 to 20 : 1 and a temperature of 250-500‹ C. may be used.
