Use

2,2'-Azobis(2-methylpropionitrile) is a particularly excellent free radical initiator , nitrogen will be released by the decomposition when it is heated to about 70 ° C and free radicals (CH3) 2CCN is generated which is affected by cyano radical , more stable. It can react with other organic substrates, and then generates a new radical in annihilation of itself , causing chain reaction of free radicals (see radical reaction). At the same time, it can also be two coupled molecules, generating highly toxic tetramethoxysilane succinonitrile (TMSN). AIBN melts when heated to 100~107 ° C and dramaticly decomposes, releases nitrogen and several organic nitrile compound toxic to humans, and may cause an explosion, fire. Slowly decomposes at room temperature, and it should be stored at 10 ° C or less. Away from fire, heat source. poisonous. Metabolizes into hydrocyanic acid in the blood, liver, brain and other tissues of animals. The above information is edited by the Chemicalbook of Tian Ye.
