Abstract: Adiponitrile is produced by entraining solid free-flowing adipic acid in a current of ammonia and introducing the mixture, at a temperature of below 50 DEG C., into a fluidized bed of a dehydration catalyst at 250-550 DEG C., the bed being fluidized by ammonia, and the total molar ratio of ammonia to adipic acid being at least 2: 1. Variations of the procedure are described. Suitable catalysts are silica gel, boron phosphate and catalysts containing phosphoric acid, and which may be activated by small amounts of alkali metal oxides.
