Azobisisobutyronitrile (AIBN) is an organic compound with the chemical formula C8H12N4. It is a white crystalline powder, insoluble in water, soluble in various organic solvents such as ethanol, ether, toluene, methanol, etc. It is mainly used for rubber, Plastics and other foaming agents, polymerization initiators, and can also be used in organic synthesis.
Advantages of free radical initiators Advantages of azobisisobutyronitrile as a free radical initiator: the decomposition temperature (65-85°C) is suitable for most reactions; the first-order decomposition rate varies little with different solvents; it is not easily affected by free radicals radical attack, so induced decomposition and transfer reactions are negligible; can be decomposed by light at lower temperatures.
Main uses Azobisisobutyronitrile (AIBN) is the most commonly used azo initiator. Its characteristic is that the decomposition reaction is relatively stable, only one free radical is generated, and basically no induced decomposition occurs, so it is often used in the kinetic research of free radical polymerization. In addition, it is relatively stable and safe to store and use. Like all azo compounds, AIBN also has certain toxicity and cannot be used in the synthesis of polymers related to medical and food packaging. Because its decomposition reaction produces a stoichiometric amount of nitrogen, it can often be easily released by measuring its decomposition. The volume of nitrogen gas was used to determine kinetic data such as its decomposition activation energy and frequency factor. The polymer can also sometimes be foamed with evolved nitrogen. Its decomposition temperature is 50～70℃, and its decomposition activation energy is 129kJ/mol, which belongs to low activity initiator.
