Chemical Properties:
Acrylonitrile yog cov kua uas tsis muaj xim, flammable. Nws cov vapors tuaj yeem tawg thaum raug nplaim taws. Acrylonitrile tsis tshwm sim lawm. Nws yog tsim nyob rau hauv loj heev los ntawm ob peb chemical industries nyob rau hauv lub tebchaws United States, thiab nws yuav tsum tau thiab xav tau yog nce nyob rau hauv xyoo tas los no. Acrylonitrile yog ib qho ua tau hnyav, tsis muaj nitrile. Nws yog siv los ua lwm yam tshuaj xws li yas, hluavtaws roj hmab, thiab acrylic fibers. Nws tau siv los ua tshuaj tua kab fumigant yav dhau los; Txawm li cas los xij, tag nrho cov kev siv tshuaj tua kab tau raug txiav lawm. Cov tshuaj no yog cov tshuaj nruab nrab loj siv los tsim cov khoom lag luam xws li tshuaj, tshuaj tua kab mob antioxidants, thiab dyes, nrog rau cov organic synthesis. Cov neeg siv khoom loj tshaj plaws ntawm acrylonitrile yog cov kev lag luam chemical uas ua rau acrylic thiab modacrylic fibers thiab cov khoom siv siab ABS yas. Acrylonitrile kuj tseem siv rau hauv cov tshuab ua lag luam, lub nra, cov khoom siv, thiab kev tsim cov styrene-acrylonitrile (SAN) yas rau tsheb, khoom siv hauv tsev, thiab cov khoom ntim. Adiponitrile yog siv los ua nylon, dyes, tshuaj, thiab tshuaj tua kab.
Daim ntawv thov:
Acrylonitrile yog siv los tsim polypropylene fiber ntau (xws li hluavtaws fiber ntau acrylic), acrylonitrile-butadiene-styrene yas (ABS), styrene yas, thiab acrylamide (acrylonitrile hydrolysis khoom). Tsis tas li ntawd, kev haus dej cawv ntawm acrylonitrile ua rau acrylates, thiab lwm yam. Acrylonitrile tuaj yeem ua polymerized rau hauv cov kab hluav taws xob polymer compound, polyacrylonitrile, nyob rau hauv qhov kev txiav txim ntawm ib qho pib (peroxymethylene). Acrylonitrile muaj kev ntxhib los mos, zoo ib yam li cov ntaub plaub, thiab feem ntau hu ua "cov ntaub plaub tsiaj cuav". Nws muaj lub zog siab, lub teeb tshwj xeeb lub ntiajteb txawj nqus, zoo thaum tshav kub kub tuav, thiab tiv taus tshav ntuj, acids, thiab cov kuab tshuaj feem ntau. Nitrile roj hmab ua los ntawm copolymerization ntawm acrylonitrile thiab butadiene muaj roj zoo, tiv taus txias, hnyav tsis kam thiab lwm yam khoom, thiab yog cov roj hmab tseem ceeb tshaj plaws hauv kev lag luam niaj hnub, thiab siv dav.
