He aha ka 4,4'-Azobis(4-cyano-1-pentanol) CAS 4693-47-4?

4,4'-Azobis (4-cyanovaleric acid) he paʻa keʻokeʻo keʻokeʻo ma ka lumi wela a me ke kaomi. Loaʻa iā ia ka acidity nui a me ka paʻa kemika maikaʻi ʻole. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik. . ʻO 4,4'-azobis (4-cyanovaleric acid) he mea hoʻomaka polymer i maʻalahi i ka mālamalama ikaika a hiki ke hoʻohana ʻia i ka hana ʻana o ka polyvinyl chloride, polyacrylonitrile, Production a me ka hoʻomākaukau ʻana i nā polymers e like me ka vinyl alcohol a me nā fiber optical synthetic.

1. Hoʻohana i ka polymerization reactions

ʻO 4,4'-azobis(4-cyanopentanol) he hui azo hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no nā hopena polymerization. I ke kaʻina o ka polymerization radical manuahi, hiki iā ia ke decompose e hana i nā radical manuahi e hoʻomaka i ka polymerization monomer. No ka laʻana, i ka hopena polymerization o nā monomer vinyl e like me nā acrylates a me nā styrenes, hiki iā ia ke hoʻomalu pono i ka hoʻomaka a me ka wikiwiki o ka hopena polymerization. Hiki i nā radical manuahi i hana ʻia e kona decomposition ke hoʻomaka i ka wehe ʻana o nā mea paʻa pālua i loko o nā molekele monomer, a laila hoʻopili kekahi i kekahi e hana i nā kaulahao polymer.

Loaʻa i kēia mea hoʻomaka kekahi mau pōmaikaʻi, e like me ka hāʻawi ʻana i ka helu o ka hanauna radical manuahi ma lalo o nā kūlana wela kūpono, i hiki ai i ka hopena polymerization ke holo mālie, kahi kūpono i ka synthesis o nā polymers me ka hāʻawi ʻana i ke kaumaha molecular haiki.

2. Hana i ka hoʻomākaukau ʻana i nā mea hoʻohua

Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea huʻa. 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 pūʻulu hana ʻē aʻe i hana ʻia e kona decomposition e kōkua pū i ka crosslinking a me ka mālama ʻana i nā matrices polymer e like me ka polyurethane. ʻO kēia hopena pālua ka mea e hiki ai i ka mea huʻihue ke hana i kahi ʻano pore kūlike, a hiki ke hoʻomalu ʻia ka nui a me ka hāʻawi ʻana i nā pores e ka hoʻoponopono ʻana i nā kūlana e like me kā lākou dosage, a laila e hoʻomaikaʻi ai i nā waiwai kino o ka mea hoʻoulu, e like me ka hōʻemi ʻana i ka nui o nā mea, hoʻomaikaʻi i ka elasticity a me nā waiwai cushioning, etc.
