Yini i-4,4'-Azobis(4-cyano-1-pentanol) CAS 4693-47-4?

I-4,4'-Azobis (4-cyanovaleric acid) iyisiqinile esimhlophe ukuya kokumhlophe endaweni yezinga lokushisa kanye nokucindezela. Ine-asidi ebalulekile kanye nokungaqini kahle kwamakhemikhali. Ayincibiliki kahle emanzini kodwa incibilika kuzincibilikisi zemvelo ezinotshwala. . I-4,4'-azobis(4-cyanovaleric acid) iyisiqalisi se-polymer esizwela ukukhanya okuqinile futhi singasetshenziswa ekukhiqizeni i-polyvinyl chloride, i-polyacrylonitrile, Ukukhiqizwa nokulungisa ama-polymers afana ne-vinyl alcohol kanye ne-synthetic optical fibers.

Isicelo

1. Isicelo ekuphenduleni kwe-polymerization

I-4,4'-azobis(4-cyanopentanol) iyinhlanganisela ye-azo engasetshenziswa njengesiqalo sokusabela kwe-polymerization. Enqubweni ye-polymerization yamahhala, ingabola ukuze ikhiqize ama-radicals mahhala ukuze iqalise i-monomer polymerization. Isibonelo, ekuphenduleni kwe-polymerization yama-vinyl monomers afana nama-acrylates nama-styrenes, angakwazi ukulawula ngempumelelo ukuqaliswa kanye nesilinganiso sokusabela kwe-polymerization. Ama-radicals amahhala akhiqizwa ukubola kwawo angaqala ukuvulwa kwezibopho eziphindwe kabili kuma-molecule e-monomer, bese exhuma omunye nomunye ukuze akhe amaketanga e-polymer.

Lesi siqalisi sinezinzuzo ezithile, njengokuhlinzeka ngezinga elizinzile ngokuqhathaniswa lokudalwa kwama-radical mahhala ngaphansi kwezimo zokushisa ezifanele, ukuze ukusabela kwe-polymerization kuqhubeke kahle, okulungele ukuhlanganiswa kwama-polymer anesisindo sokusabalalisa se-molecule encane.

2. Iqhaza ekulungiseni izinto ezigwazayo

Ingase futhi isetshenziselwe ukulungisa amagwebu. Ekulungiseni izinto ezinogwebu ezifana ne-polyurethane, i-4,4'-azobis(4-cyanopentanol) ingabamba iqhaza ekuphenduleni ukukhiqiza igesi, futhi ama-radicals mahhala namanye amaqembu asebenzayo akhiqizwa ukubola kwawo nawo afaka isandla ekuxhumaneni nasekuphulukisweni kwamatrices e-polymer njenge-polyurethane. Lo mphumela ombaxambili uvumela izinto ezigwebuyo ukuthi zakhe ukwakheka kwembotshana efanayo, futhi ubukhulu nokusabalalisa kwezimbotshana kungalawulwa ngokulungisa izimo ezifana nomthamo wazo, ngaleyo ndlela kuthuthukiswe izakhiwo ezibonakalayo zezinto ezigwebu, njengokunciphisa ukuminyana kwezinto, ukuthuthukisa ukunwebeka kwempahla kanye nezakhiwo zokugudluza, njll.
