Azobisisobutyronitrile
2, 2-azobisisobutyronitrile(aibn)
Molecular formula:c 8 h 12 n 4 molecular weight:164.21 cas no:78-67-1
Synonyms: 2, 2-azobis(2-methylpropanenitrile)[vazo64] physical nature: azobisisobutyronitrile is white crystal or crystalline powder, easily to dissolve in the methyl alcohol, ethanol, acetone, ethylether, light petroleum etc. The product decomposes flashly and releases nitrogen gas in the position of heating and decomposes slowly under ordinary temperature, which should be stored under 20¦.
Use: azobisisobutyronitrile is a initiator in the polymerization of vinyl chloride, vinylacetate, acrylonitrile, methyl methylacrylate, and styrene. It is also as a foamer of plastic and rubber, and moreover, it can used in organic synthesis.
