Adiponitrile CAS 111-69-3

Adiponitrile (ADN), also known as 1,4-dicyanobutane, is a colorless and transparent oily liquid with a slightly bitter taste. Soluble in methanol, ethanol, chloroform. Insoluble in water, cyclohexane, ether, carbon disulfide and carbon tetrachloride.

Adiponitrile is an organic compound having the molecular formula (CH2)4(CN)2 and is a precursor of an important polymer nylon 66. In 2005, its production could reach 100 million kilograms. About 90% of the world’s annual production of adiponitrile is used in the production of nylon 66 salts.

At present, the methods for producing adiponitrile in industry are mainly adipic acid ammoniation method, butadiene method and acrylonitrile dimerization method. Among them, butadiene hydrogenation to produce adiponitrile has the advantages of easy availability of raw materials, low energy consumption, It has the advantages of low cost, short process flow, large-scale production, high yield, high product quality, and low environmental pollution. It is the most advanced adiponitrile production process in the world.
