What does AIBN do in a reaction?
Reaction. AIBN decomposes to create the 2-cyano-2-propyl radical, which then abstracts the hydrogen off of tributyltin hydride. This results in a tributyltin radical, which can be used in numerous reactions. For example, this radical could be used to remove a bromine from an alkene.
What temperature does AIBN decompose?
65-80 degrees Celsius
AIBN decomposes at 65-80 degrees Celsius . At high temperatures more than 100 degrees celsius ,AIBN is not suitable initiator due to high decomposition rate.

Why is AIBN explosive?
The explosion was induced by overheating of the agitator impeller shaft. The overheating was caused by friction from excessively tightened gland packing at a shaft-seal. It might have been prevented by communicating operation methods and daily hazard predicting activities.
What is the density of AIBN?
1.1 g/cm³Azobisisobutyronitrile / Density
What is the function of AIBN in the synthesis of polyethylene?
It is often used as a foamer in plastics and rubber and as a radical initiator. In most characteristic reaction, AIBN decomposes, eliminating a molecule of nitrogen gas to form two 2-cyanoprop-2-yl radicals: These radicals can initiate free-radical polymerizations and other radical-induced reactions. 1.
What is the boiling point of AIBN?
457.2°F (236.2°C)Azobisisobutyronitrile / Boiling point
What are free-radical polymerisation reaction initiators?
Free-radical polymerization (FRP) is a method of polymerization, by which a polymer forms by the successive addition of free-radical building blocks. Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules.
Are the good initiators for free radical chain polymerisation?
To explain I would say: For free radical chain polymerisation, Benzoyl peroxide and hydrogen peroxide are the good initiators. They produce monomer free radicals.
