ʻO ka wehewehe a me ke ʻano o ka Acrylonitrile
E hoʻomaka kākou ma ka hoʻolauna ʻana i ka acrylonitrile ma mua o ka neʻe ʻana i nā kumuhana ʻē aʻe.ʻO ka Acrylonitrile kahi mea hoʻohuihui kino i loaʻa ke ʻano kemika CH2 CHCN.Hoʻokaʻawale ʻia ʻo ia ma ke ʻano he mea hoʻohuihui no ka mea ʻo ia ka hapa nui o ke kalapona a me ka hydrogen atoms.Ma ke kumu, a ma ke ʻano o nā pūʻulu hana (nā pūʻulu koʻikoʻi a ʻokoʻa o nā mana), ʻelua mau mea koʻikoʻi ka acrylonitrile, kahi alkene a me kahi nitrile.ʻO ka alkene kahi pūʻulu hana i loaʻa i kahi paʻa kalapona-kāpona paʻa pālua, aʻo ka nitrile kahi i loaʻa i kahi paʻa kolu kalapona-nitrogen.
Nā waiwai o Acrylonitrile
I kēia manawa ua kamaʻāina mākou i ke ʻano o ka acrylonitrile, e neʻe mākou i ke kamaʻilio e pili ana i kekahi o kāna mau waiwai nui.Ke kūʻai ʻia mai nā mea hoʻolako kemika, hele mai ka acrylonitrile ma ke ʻano he wai maʻemaʻe ʻole.Inā he ʻula melemele kona, ʻo ia ka mea maʻamau he haumia a pono paha e hoʻomaʻemaʻe ʻia (hoʻomaʻemaʻe wai) ma mua o ka hoʻohana ʻia ʻana no nā hopena kemika a me nā mea o ia ʻano.Ua ana ʻia ka helu hoʻolapalapa o Acrylonitrile he 77 degere Celsius, he haʻahaʻa iki no ka wai kūlohelohe.Me kēia wahi hoʻolapalapa haʻahaʻa, ʻike ʻia ka acrylonitrile i kekahi manawa ma ke ʻano he mea hoʻohuihui, ʻo ia hoʻi, e holo koke nā molekole acrylonitrile wai i loko o ka māhele kinoea a e mahuka.No kēia kumu, he manaʻo maikaʻi ʻaʻole e waiho i kahi ʻōmole acrylonitrile e hāmama i ka lewa no ka mea e mahuka koke ia.
Hoʻohana
ʻO ka hoʻohana mua ʻana o ka acrylonitrile e like me ka mea maka no ka hana ʻana i nā fibers acrylic a me modacrylic.ʻO nā mea hoʻohana nui ʻē aʻe e pili ana i ka hana ʻana o nā plastics (acrylonitrile-butadiene-styrene (ABS) a me styrene-acrylonitrile (SAN)), nā nitrile rubbers, nitrile barrier resins, adiponitrile a me ka acrylamide
Ua hoʻohana ʻia ka Acrylonitrile, i loko o ka hui ʻana me ka carbon tetrachloride, ma ke ʻano he fumigant no ka wili palaoa a me nā lako hana ʻai palaoa a no ka paka mālama ʻia.Eia naʻe, ʻo ka hapa nui o nā huahana pesticide i loaʻa ka acrylonitrile ua hoʻihoʻi ʻia e nā mea hana.I kēia manawa, hoʻopaʻa inoa ʻia ka acrylonitrile i hui pū ʻia me ka carbon tetrachloride ma ke ʻano he pesticide i kaupalena ʻia.Ua hoʻohana ʻia ka 51% o ka ʻai ʻana o ka acrylonitrile o ʻAmelika Hui Pū ʻIa no nā fibers acrylic, 18% no nā resins ABS a me SAN, 14% no adiponitrile, 5% no ka acrylamide a me 3% no nā elastomers nitrile.ʻO ke koena 9% no nā hoʻohana like ʻole (Cogswell 1984).
