Products Description of 2,2'-Azobis(2-methylpropionitrile) CAS#78-67-1

Azobisisobutyronitrile (abbreviated AIBN) is an organic compound with the formula [(CH3)2C(CN)]2N2. This white powder is soluble in alcohols and common organic solvents but is insoluble in water. It is often used as a foamer in plastics and rubber and as a radical initiator. It's soluble in a wide variety of organic solvents, including alcohol-based solvents. Insoluble in water and denser than water. Moderately toxic by ingestion. Readily ignited by sparks or flames. Burns intensely and persistently. Toxic oxides of nitrogen produced during combustion. Used as a catalyst, in vinyl polymerizations and a blowing agent for plastics.

Product Application of 2,2'-Azobis(2-methylpropionitrile) CAS#78-67-1

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.
