Specification
The cas register number of 2-Chloroacrylonitrile is 920-37-6,its IUPAC name is 2-chloroprop-2-enenitrile . It also can be called as 2-Chloro-2-propenenitrile ; Chloroacrylonitrile ; 2-Propenenitrile, 2-chloro- ; Acrylonitrile, 2-chloro- .It is a clear, yellow liquid, a highly flammable.It readily polymerizes, and copolymerizes with other unsaturated monomers. If inhalation or contact with material may irritate or burn skin and eyes, and if happen to meet fire may produce irritating, corrosive and/or toxic gases. Its vapors may cause dizziness or suffocation. And if runoff from fire control or dilution water may cause pollution.
2-Chloroacrylonitrile belongs to the product categories like Boron, Nitrile, Thio,TM-Cpds;Aliphatics;Nitriles;C1 to C5;Cyanides/Nitriles;Nitrogen Compounds.Its vapour pressure is 58.4 mmHg at 25°C and enthalpy of vaporization is 32.96 kJ/mol.
