Title:
METHOD FOR PREPARING ADIPONITRILE
Document Type and Number:
WIPO Patent Application WO/2020/248403
Kind Code:
A1
Abstract:
Disclosed is a novel method for preparing adiponitrile. According to the method, an adipic acid diester and ammonia gas are used as raw materials, and same are subjected to a catalytic ammonolysis-dehydration reaction to directly prepare adiponitrile, and only water and corresponding alcohols are generated as by-products. The method for preparing adiponitrile avoids the use of highly toxic hydrocyanic acid as a raw material, and has a simple reaction process, a cheap and easily available catalyst, a high raw material conversion rate, a high product selectivity and is easy to separate.
