The invention discloses a method for preparing adiponitrile by catalytic conversion of 1,6-hexanediol. The method is characterized in that oxygen or air is used as an oxygen source, ammonia water, ammonia gas or an ammonium salt is used as a nitrogen source, alcohol, ether, nitrile or hydrocarbon with a low boiling point is used as a solvent, and 1,6-hexanediol is subjected to ammoxidation reaction under the action of a catalyst to obtain adiponitrile. By adopting the method, the raw material utilization ratio is high, the catalyst is easy to recover for cycle use, and the target product is easy to separate and purify. |
