4,4′-Azobis(4-cyano-1-pentanol) CAS 4693-47-4
He ʻano paʻa keʻokeʻo a keʻokeʻo paha ka 4,4'-Azobis (4-cyanovaleric acid) ma ka mahana o ka lumi a me ke kaomi. He nui kona ʻakika a he paʻa kemika haʻahaʻa. He palupalu ia i ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik ʻona. . ʻO 4,4'-azobis (4-cyanovaleric acid) kahi mea hoʻomaka polymer i maʻalahi i ka mālamalama ikaika a hiki ke hoʻohana ʻia i ka hana ʻana o ka polyvinyl chloride, polyacrylonitrile, Hana ʻana a me ka hoʻomākaukau ʻana o nā polymers e like me ka vinyl alcohol a me nā fiber optical synthetic.

1. Hoʻohana ʻia i nā hopena polymerization
ʻO 4,4'-azobis (4-cyanopentanol) kahi hui azo hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no nā hopena polymerization. I ke kaʻina hana o ka polymerization radical manuahi, hiki iā ia ke palaho e hana i nā radical manuahi e hoʻomaka i ka polymerization monomer. No ka laʻana, i ka hopena polymerization o nā monomers vinyl e like me acrylates a me styrenes, hiki iā ia ke hoʻomalu pono i ka hoʻomaka ʻana a me ka wikiwiki o ka hopena polymerization. Hiki i nā radical manuahi i hana ʻia e kona palaho ke hoʻomaka i ka wehe ʻana o nā pilina pālua i loko o nā molekala monomer, a laila e hoʻopili kekahi i kekahi e hana i nā kaulahao polymer.
Loaʻa i kēia mea hoʻomaka kekahi mau pono, e like me ka hāʻawi ʻana i kahi helu hanauna radical manuahi paʻa ma lalo o nā kūlana mahana kūpono, i hiki ai i ka hopena polymerization ke holo mālie, kahi e kūpono ai i ka synthesis o nā polymers me kahi hoʻolaha kaumaha molekala haiki.
2. Kūlana i ka hoʻomākaukau ʻana i nā mea hoʻohuʻu
Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea hoʻohua. I ka hoʻomākaukau ʻana i nā mea hoʻohua e like me ka polyurethane, hiki i ka 4,4'-azobis (4-cyanopentanol) ke komo i ka hopena e hana i ke kinoea, a ʻo nā radical manuahi a me nā hui hana ʻē aʻe i hana ʻia e kona decomposition e kōkua pū i ka crosslinking a me ka hoʻōla ʻana o nā matrices polymer e like me ka polyurethane. ʻO kēia hopena pālua e hiki ai i ka mea hoʻohua ke hana i kahi ʻano pore like, a hiki ke hoʻomalu ʻia ka nui a me ka hoʻolaha ʻana o nā pores ma ka hoʻoponopono ʻana i nā kūlana e like me kā lākou dosage, no laila e hoʻomaikaʻi ana i nā waiwai kino o ka mea hoʻohua, e like me ka hoʻemi ʻana i ka nui o ka mea, ka hoʻomaikaʻi ʻana i ka elasticity o ka mea a me nā waiwai cushioning, a pēlā aku.
