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. As an azo initiator, radicals resulting … See more In its most characteristic reaction, AIBN decomposes, eliminating a molecule of nitrogen gas to form two 2-cyanoprop-2-yl radicals: Because azobisisobutyronitrile readily gives off free … See more AIBN is produced from acetone cyanohydrin and hydrazine, then followed by oxidation: 2 (CH3)2C(CN)OH + N2H4 → [(CH3)2C(CN)]2N2H2 … See more • SIDS Initial Assessment Report for 2,2′-Azobis(2-methylpropionitrile) from the Organisation for Economic Co-operation and Development (OECD) See more These radicals formed by the decomposition of AIBN can initiate free-radical polymerizations and other radical-induced reactions. For instance, a mixture of styrene and maleic anhydride in toluene will react if heated, forming the copolymer upon addition of AIBN. … See more AIBN is safer to use than benzoyl peroxide (another radical initiator) because the risk of explosion is far less. However, it is still considered as an explosive compound, decomposing above 65 °C.
