| titleOfInvention | Preparation method of adiponitrile |
| abstract | The invention relates to a novel method for preparing adiponitrile. The method adopts adipic acid diester and ammonia gas as raw materials, and directly prepares adiponitrile through catalytic ammonolysis-dehydration reaction, and only by-products are generated to produce water and corresponding alcohol. The preparation method of adiponitrile avoids using virulent hydrocyanic acid as a raw material, and has the advantages of simple reaction process, cheap and easily-obtained catalyst, high raw material conversion rate, high product selectivity and easy separation. |
