Aibn




These radicals can be used to start up Free Radical Polymerization s. For instance a mixture of Styrene and Maleic Anhydride in Toluene will react if heated very slowly to form the Polystyrene Polymer unless an Initiator such a AIBN is present. Another example of Free Radical Polymerization is the hydrohalogenation of alkenes.

AIBN is safer to use than Benzoyl Peroxide (another Radical Initiator ) because the risk of explosion is far smaller. However, it is considered a flammable solid.
The melting point of AIBN is 103-105°C. It is soluble in methanol & ethanol, but insoluble in water. It can explode if dissolved in acetone.
AIBN is highly toxic. Wear a respirator/dust mask, protective gloves, & safety glasses when handling AIBN.
