Azobisisobutyronitrile

Description:
Azobisisobutyronitrile (AIBN) is a chemical compound commonly used as a radical initiator in polymerization processes. It is characterized by its stable azo group, which decomposes upon heating or exposure to light, generating free radicals that initiate polymerization reactions. AIBN is a white to pale yellow crystalline solid with a relatively low melting point. It is soluble in organic solvents such as acetone, ethyl acetate, and dichloromethane, but insoluble in water. The compound is known for its ability to produce radicals at elevated temperatures, making it valuable in the synthesis of various polymers, including plastics and resins. AIBN is also used in the production of copolymers and in the modification of existing polymers. However, it should be handled with care due to its potential hazards, including being a skin and eye irritant and its ability to form explosive mixtures under certain conditions. Proper safety protocols should be followed when working with this compound in laboratory or industrial settings.
