Acrylonitrile CAS#107-13-1
Acrylonitrile is a colorless, flammable liquid, and its vapors may form explosive mixtures when exposed to open flames. It does not occur naturally in the environment and is produced in large quantities by various chemical industries, particularly in the United States, where demand has continued to rise in recent years.
As a highly produced unsaturated nitrile, acrylonitrile is an important raw material for the manufacture of plastics, synthetic rubber, and acrylic fibers. Although it was previously used as a pesticide fumigant, all such applications have now been discontinued.
Acrylonitrile is a key chemical intermediate widely used in the production of pharmaceuticals, antioxidants, dyes, and various organic synthesis products. Its largest consumption is in industries producing acrylic and modacrylic fibers, as well as high-impact ABS plastics.
In addition, acrylonitrile is utilized in the production of styrene-acrylonitrile (SAN) plastics, which are commonly applied in automotive components, household goods, packaging materials, business equipment, luggage, and construction materials. Related derivatives such as adiponitrile are further used in the manufacture of nylon, dyes, pharmaceuticals, and pesticides.

Product Application of Acrylonitrile CAS#107-13-1
Acrylonitrile is widely used in the production of acrylic fibers, resins, and surface coating materials. It also serves as an important intermediate in the manufacture of pharmaceuticals and dyes, and is used as a polymer modifier as well as a fumigant.
In addition, acrylonitrile may be generated in fire effluent gases due to the pyrolysis of polyacrylonitrile-based materials.
Studies have shown that acrylonitrile can migrate from acrylonitrile–styrene copolymer and acrylonitrile–styrene–butadiene copolymer containers when they are filled with food-simulating solvents such as water, 4% acetic acid, 20% ethanol, and heptane, and stored for periods ranging from 10 days to 5 months. This release increases with rising temperature and is mainly attributed to residual acrylonitrile monomers remaining in the polymer materials.
