Abstract

1431511 Purification of acrylonitrile BP CHEMICALS INTERNATIONAL Ltd 19 Dec 1974 [7 Jan 1974] 00668/74 Heading C2C Acrylonitrile that has been produced by the vapour phase reaction of acrolein or a substance giving rise to acrolein under the reaction conditions, molecular oxygen and ammonia at elevated temperature in the presence of a catalyst, and that contains acrolein and hydrogen cyanide as by-products, is purified by treating with an ammonium, alkalimetal or alkaline earth metal salt of a weak aliphatic carboxylic acid to cause the acrolein and hydrogen cyanide to react to form acrolein cyanhydrin, and separating the acrylonitrile from the acrolein cyanhydrin by distillation. The salt is preferably an acetate, propionate, butyrate or stearate and may be used as a solid or aqueous or organic solution; in examples, aqueous ammonium acetate is used.
