ukusetshenziswa
I-AIBN iyisiqalisi se-free radical esihle kakhulu. Uma ishiswa ibe cishe ngu-70 ° C, iyabola futhi ikhiphe igesi ye-nitrogen, ikhiqize ama-free radical (CH3)2CCN. Ama-Free radicals azinzile kakhulu ngenxa yethonya lamaqembu e-cyanide. Ingasabela nenye i-substrate ephilayo, izibhubhise, futhi ivuseleleke ibe yi-free radical entsha, ngaleyo ndlela ibangele ukusabela kwe-chain yama-free radicals (bheka ukusabela kwe-free radical), Uma ifudumeza i-AIBN ibe ngu-100-107 ° C, iyancibilika futhi ibole ngokushesha,
Isetshenziswa njengesiqalisi se-polymerization sama-monomers afana ne-polyvinyl chloride, i-polyvinyl alcohol, i-polystyrene, kanye ne-polyacrylonitrile. Isetshenziswa njengesisunguli se-organic synthesis. Isetshenziswa njengesiqalisi sama-polymers amaningi ama-molecule
Isetshenziswa njengesiqalisi se-polymerization noma i-copolymerization ye-vinyl acetate kanye ne-acrylic esters.
Isetshenziswa njenge-ejenti yokugwedla.
Ukusetshenziswa: Isikhuthazi sokufaka izicubu ku-methyl methacrylate. Umqalisi we-polymer. Irabha, ipulasitiki, i-ejenti yokugqwala. Isiqalisi sepulasitiki se-polychloroethylene
4. I-AIBN, 2,2'-Azobis(2-methylpropionitrile (CAS: 78-67-1) Ukupakishwa Nokuthunyelwa
25KG/Isikhwama noma 25KG/Isigubhu
