What is Azobisisobutyronitrile?
Azodiisobutyronitrile (AIBN) is a natural substance with a molecular formula of [( CH3) 2C (CN)] 2n2. This white powder is soluble in alcohols and normal organic solvents, however not in water. It is typically made use of as foaming representative as well as totally free extreme initiator in plastics as well as rubber. It is soluble in a variety of natural solvents, consisting of alcohol based solvents. It is insoluble in water as well as has a higher thickness than water. Modest toxicity by ingestion. Conveniently ignited by stimulates or fires. Burn highly and persistently. Toxic nitrogen oxides generated throughout burning. Utilized as stimulant, plastic polymerization response and plastic lathering agent.
2,2′-Azobis(2-methylpropionitrile) is a particularly outstanding cost-free radical initiator. When heated up to about 70 ℃, it decays to release nitrogen, as well as is affected by cyano teams to produce free radical (CH3) 2ccn, which is a lot more secure. It can respond with various other natural substrates, and then obliterate on its own to produce new totally free radicals, creating a domino effect of free radicals (see complimentary radical reaction). At the same time, it can likewise be two coupling molecules to generate the highly toxic tetramethoxysilane Succinonitrile (TMSN).
When AIBN is heated to 100 ~ 107 ℃, it thaws and breaks down violently, releasing nitrogen and also several organic nitrile compounds poisonous to body, which may create surge and fire. It breaks down slowly at normal temperature level and also ought to be stored below 10 ℃. Avoid fire source and also warmth resource. Harmful. It is metabolized into hydrocyanic acid in the blood, liver, mind as well as other cells of animals.
2,2 ‘- Azobis (2-methylpropionitrile) is made use of as an initiator in radical polymerization of polymers due to the fact that its particles are easy to go through breaking responses and kind particles with high activation energy. 2,2 ‘- azobis (2-methylpropionitrile) (AIBN) is the most generally made use of azo initiator. Its particular is that the decomposition reaction is fairly secure, only one totally free radical is generated, and also basically no generated decay occurs. Consequently, it is commonly utilized in the kinetic research study of totally free extreme polymerization.
Azodiisobutyronitrile (AIBN) is an azo substance extensively made use of as an extreme initiator. The compound has unstable carbon nitrogen covalent bond, which can be homocleaved under thermal, chemical or photochemical problems to generate complimentary radicals. They can be made use of in lots of reactions, such as halogenation, polymerization of vinyl monomers, graft response, healing of rubber and unsaturated polymers, and also crosslinking of polyolefins. AIBN can be used as an initiator for the synthesis of very crosslinked poly (divinylbenzene) (pdvb) polymers. It can likewise be utilized as an initiator in the polymerization of 2-hydroxyethyl methacrylate (HEMA).
2,2 ‘- Azobis (2-methylpropionitrile) (AIBN) is a radical initiator. AIBN remedy can be used to launch radical caused reactions, particularly radical polymerization. It can be made use of to:
- Styrene vinylpyridine diblock copolymer was synthesized by relatively easy to fix enhancement fracture chain transfer (RAFT) polymerization.
- Prep work of carboxysilica glass.
- Synthesis of poly [n – (p-vinylbenzyl) phthalimide] was used to prepare titanium dioxide composites for electrophoretic displays.

Application of Azobisisobutyronitrile
Polyurethane modification: waterborne polyurethane modification is modified by the reaction of polyurethane (PU) prepolymerized monomer, other products (modified silicone, acrylic emulsion, etc.) and AIBN initiator.
- The polyurethane prepolymer containing NCO group is reacted with hydroxyacrylic acid, and then acrylic monomer is added for free radical polymerization to obtain polyurethane acrylate (PUA). (single component).
- The OH-containing acrylic prepolymer is reacted with the NCO group-containing polyurethane prepolymer or polyisocyanate to obtain polyurethane acrylate (PUA). (two-component).
- Add blocked polyisocyanate to OH-containing acrylate polymer. (single component).
