Acrylonitrile is the Chemical Compound with the formula CH2CHCN. This pungent-smelling colorless liquid often appears yellow due to impurities. It is an important Monomer for the manufacture of useful Plastic s. In terms of its molecular structure, it consists of a Vinyl group linked to a Nitrile . USES Acrylonitrile is used principally as a for well-known Carbon-fiber . It is also a component of Synthetic Rubber . Dimerization of acrylonitrile affords adiponitrile, used in the synthesis of certain Nylon s. Small amounts are also used as a Fumigant . Acrylonitrile and derivatives such as 2-chloro-acrylonitrile are Dienophile s in Diels-Alder Reaction s. Acrylonitrile is also a precursor in the industrial manufacture of acrylamide and acrylic acid. PRODUCTION Acrylonitrile is probably the nitrile manufactured on the largest scale. Most industrial acrylonitrile is produced through the Sohio process, the Catalytic ammoxidation of Propylene : :2CH3-CH=CH2 + 2 NH3 + 3 O2 → 2CH2=CH-C≡N + 6 H2O World annual production in 2001 was 4 million Tonne s and in 2005 6 million tonnes, with just under half of that coming from the United States . In 1996 the Sohio acrylonitrile process was designated an ACS National Historical Chemical Landmark in recognition of the innovative single-step method of production that made acrylonitrile available for chemical manufacturing worldwide. {Link without Title} SAFETY Acrylonitrile is highly flammable and toxic. It undergoes Explosive Polymerization . The burning material releases fumes of Hydrogen Cyanide and Oxides Of Nitrogen . Acrylonitrile is classified as a possible human Carcinogen ( IARC Group 2B ).
