Manufactur standard Azo Polymerization Initiator - 2,2′-Azobis(2-methylpropionitrile) (CAS：78-67-1) – IDE Detail:

Azobisisobutyronitrile, AIBN for short, chemical formula is C8H12N4, soluble in organic solvents such as methanol, ethanol, ether, acetone, petroleum ether and aniline. When heated, it will release nitrogen and organic cyanide containing -(CH2)2-C-CN group. It decomposes slowly at room temperature and rapidly decomposes at 100°C. Can cause explosion and fire, flammable. poisonous. The organic cyanide released is more harmful to human body.

Properties

White crystal or crystalline powder, insoluble in water, soluble in ether, methanol, ethanol, propanol, chloroform, dichloroethane, ethyl acetate, benzene, etc., mostly oil-soluble initiators. It decomposes when heated, the melting point is 100℃-104℃. It should be stored in a dry place at 20°C. In case of moisture, it releases nitrogen and organic cyanide containing -(CH2)2-C-CN group. The decomposition temperature is 64℃. It decomposes slowly at room temperature, and rapidly decomposes at 100℃, which can cause explosion and fire, which is flammable and toxic. Release nitrogen and organic cyanide, the latter is more harmful to human body.

Uses

Azobisisobutyronitrile is an oil-soluble azo initiator. The azo initiator has a stable reaction, is a first-order reaction, has no side reactions, and is relatively easy to control, so it is widely used in the research and production of polymers. Such as vinyl chloride, vinyl acetate, acrylonitrile and other monomer polymerization initiators, can also be used as polyvinyl chloride, polyolefin, polyurethane, polyvinyl alcohol, acrylonitrile and butadiene and styrene copolymer, polyisocyanate, polyacetate Blowing agent for vinyl ester, polyamide and polyester. In addition, it can also be used in other organic synthesis.

Product usage

Used as a polymerization initiator for monomers such as polyvinyl chloride, polyvinyl alcohol, polystyrene, polyacrylonitrile; as an initiator for the polymerization of vinyl chloride, vinyl acetate, acrylonitrile and other monomers, and also as a rubber , Plastic foaming agent, the dosage is 10% to 20%. This product can also be used as vulcanizing agent, pesticide and intermediate in organic synthesis. This product is a highly toxic substance, and the oral LD5017.2～25mg/kg to mice, the organic cyanide released by heat decomposition is more toxic to the human body. Organic synthesis intermediates; used as initiators of high molecular polymers.
