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. As an azo initiator, radicals … Visa mer 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 … Visa mer AIBN is produced from acetone cyanohydrin and hydrazine, then followed by oxidation: 2 (CH3)2C(CN)OH + N2H4 → [(CH3)2C(CN)]2N2H2 + 2 H2O [(CH3)2C(CN)]2N2H2 + Cl2 → [(CH3)2C(CN)]2N2 … Visa mer • SIDS Initial Assessment Report for 2,2′-Azobis(2-methylpropionitrile) from the Organisation for Economic Co-operation and Development Visa mer These radicals formed by the decomposition of AIBN can initiate free-radical polymerizations and other radical-induced reactions. … Visa mer 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. A respirator dust mask, protective gloves and safety glasses are … Visa mer Webb4.
