Description

technical field

[0001] The invention belongs to the technical field of catalytic organic synthesis, and in particular relates to a catalyst for preparing dinitriles from alicyclic hydrocarbons and a method for catalytically synthesizing dinitriles. Background technique

[0002] With the development and application of chemical products, aliphatic dibasic nitriles, as important chemical raw materials, are gradually increasing in demand. Among them, adiponitrile can be used to produce hexamethylenediamine, a monomer of nylon 66, and can be hydrolyzed to produce adipic acid, etc., which has multiple uses. Glutaronitrile is the raw material for preparing chemical products such as diethyl glutarate, glutaric acid and 1,5-diaminopentane.

[0003] At present, the methods for preparing aliphatic dibasic nitriles mainly include diacids to prepare dinitriles, such as preparing adiponitrile from adipic acid, preparing glutaronitrile from glutaric acid, etc., and reacting chlorinated hy...
