Acrylonitrile
Acrylonitrile
Acrylonitrile is a colorless, spicy odor liquid. It is a basic organic chemical product of the public. It is a basic and important raw material for three synthetic materials - synthetic fiber, synthetic rubber and plastic. It is used in the organic synthesis industry and people's economic life. widely.

Role and Uses
Acrylonitrile is an important monomer for synthetic fibers, synthetic rubbers and synthetic resins. Polyacrylic fibers, which are made of Acrylonitrile, are very similar to wool and are therefore called synthetic wool. Acrylonitrile can be copolymerized with butadiene to produce nitrile rubber, which has good oil resistance, cold resistance, wear resistance, and electrical insulation properties, and is stable in most chemical solvents, sunlight and heat. Acrylonitrile is copolymerized with butadiene and styrene to produce ABS resin, which has the advantages of light weight, cold resistance and good impact resistance. Acrylonitrile hydrolysis can produce acrylamide and acrylic acid and their esters. They are important organic chemical raw materials. Acrylonitrile can also be obtained by electrolytic hydrogenation coupling to obtain adiponitrile. Hydrogenation of adiponitrile can also produce hexamethylenediamine. Hexamethylenediamine is a raw material of nylon 66. It can be used in the manufacture of water repellents and adhesives, as well as in other organic synthesis and pharmaceutical industries, and as a cereal fumigant. In addition, the product is also an aprotic polar solvent, as a raw material for oilfield mud auxiliaries PAC142.
Acrylonitrile is an important monomer for synthetic fibers, synthetic rubbers and synthetic resins. It is also an intermediate for insecticides filled with nitriles.
