2,2'-Azobis(2-methylpropionitrile)

2,2'-Azobis(2-methylpropionitrile) is used as an initiator in polymer radical polymerization because its molecules can easily undergo split reactions and form molecules with high activation energy. 2,2'-Azobis(2-methylpropionitrile) (AIBN) is the most commonly used azo initiator. Its characteristic is that the decomposition reaction is relatively stable, only one kind of free radical is generated, and basically no induced decomposition occurs, so it is often used in the kinetics research of free radical polymerization.
White columnar crystals or white crystalline powder. Insoluble in water, soluble in methanol, ethanol, acetone, ether, petroleum ether and aniline and other organic solvents.
