Acrylonitrile CAS 107-13-1 colorless liquid CAS 107-13-1 acrylonitrile

Short Description:

Acrylonitrile

Acrylonitrile’s vapor and air can form an explosive mixture, which can easily cause combustion and release toxic gases in case of open fire and high heat.Reacts violently with oxidants, strong acids, strong bases, amines and bromine.

Chemical properties

It is flammable.Its vapor and air can form explosive mixture. In case of open flame and high heat, it is easy to cause combustion and release toxic gas. Reacts violently with oxidants, strong acids, strong bases, amines, and bromine. Under the high temperature of the fire, the exothermic heat of polymerization can occur, causing the container to rupture.

Application

Acrylonitrile is an important monomer for synthetic fibers, synthetic rubbers and synthetic resins.The polyacrylonitrile fiber produced from acrylonitrile is acrylic fiber, its properties are very similar to wool, so it is also called synthetic wool.The copolymerization of acrylonitrile and butadiene can produce nitrile rubber, which has good oil resistance, cold resistance, abrasion resistance, and electrical insulation properties.And in most chemical solvents, sunlight and heat, the performance is relatively stable.Acrylonitrile is copolymerized with butadiene and styrene to produce ABS resin, which has the light weight, cold resistance and good impact resistance advantages.The hydrolysis of acrylonitrile can produce acrylamide,acrylic acid and its esters.They are important organic chemical raw materials. Acrylonitrile can also be electrolytically hydrogenated to produce adiponitrile, and hexamethylene diamine can be produced from the hydrogenation of adiponitrile, which is the raw material of nylon 66.It can be used to produce water repellents and adhesives, etc. It is also used in other organic synthesis,pharmaceutical industries and as a cereal fumigant.In addition, this product is also an aprotic polar solvent, which is used as a raw material for oilfield mud auxiliary PAC142.
