Acrylonitrile (AN) is a volatile liquid mostly used in manufacturing plastics and polymers.
AN may have been used as standard during headspace gas chromatography for the determination of AN monomer in plastic containers and carbonated beverages.
Acrylonitrile is used in the manufacture of acrylic fibers, resins (acrylonitrile butadiene-styrene, styrene-acrylonitrile and others) and nitrile rubbers (butadiene-acrylonitrile).
