Description:2,2' -azobis (2-methylpropionitrile) is white crystal or crystalline powder, insoluble in water, decomposed in heat, melting point 100℃-104℃. Store in a dry place at 20℃. Nitrogen and organic cyanide containing -(CH2)2-C-CN group are liberated by water. Slow decomposition at room temperature, 100℃ rapid decomposition, azo diisobutyronitrile is oil soluble azo initiator, azo initiator reaction stability, is a primary reaction, no side reactions, relatively easy to control, so widely used in polymer research and production. For example, monomer polymerization initiators such as vinyl chloride, vinyl acetate and acrylonitrile can also be used as polyvinyl chloride, polyolefin, polyaminoester, polyvinyl alcohol, acrylonitrile, butadiene and benzene ethyl copolymer, polyisocyanate, polyvinyl acetate and poly. Foaming agent for amide, polyester, etc. In addition, it can also be used in other organic synthesis.
