Acrylonitrile amagwiritsidwa ntchito mu pulasitiki ndi utomoni,
Acrylonitrile Kwa ABS Resins, Malingaliro a kampani Acrylonitrile ASA, Acrylonitrile Kwa NBR, Acrylonitrile Kwa SAN, Acrylonitrile Kwa SAR,
Acrylonitrile (ACN), organic compound, ndi madzi opanda mtundu komanso oonekera opangidwa kuchokera ku propylene ndi ammonia.Ndi zotakataka ndi poizoni m'chilengedwe;komabe, imadziwika ndi mphamvu zake komanso kulimba kwake.
Ndi monoma yomwe imapanga polyacrylonitrile, homopolymer, copolymers monga acrylic fibers, acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN), acrylonitrile styrene acrylate (ASA) ndi rubbers ena monga acrylonitrile butadieneni (BRadieneni) ntchito zazikulu za ogwiritsa ntchito.Pazogwiritsa ntchito ogwiritsa ntchito kumapeto, ABS thermoplastic imathandizira kupitilira 35 peresenti yazofunikira zonse zomwe zimatsatiridwa ndi ulusi wa acrylic zomwe zimafunikira gawo la 27 peresenti.Pafupifupi zaka zingapo zapitazo, ulusi wa acrylic ndiwo udakhala gawo lalikulu lofunikira, koma ABS yayamba kutchuka pang'onopang'ono kumbuyo kwa mphamvu yake, kulimba kwake komanso kukana kutentha komwe kumafunikira pamapulogalamu angapo akumunsi.Zida zingapo (mafiriji, khitchini, ndi zina zotero), zamagetsi ndi zamagetsi, ndi makampani amagalimoto ndi omwe amagwiritsa ntchito kwambiri ABS.Ulusi wa Acrylic umasinthidwa pang'onopang'ono ndi ulusi wa poliyesitala pamtengo wotsika komanso zosavuta kuzibwezeretsanso.Acrylonitrile imagwiritsidwanso ntchito ngati yapakatikati popanga Acrylamide, yomwe imapanga pafupifupi 15 peresenti yazomwe zimafunikira, zomwe zimapanga polyacrylamide (PAM) yomwe imagwiritsidwa ntchito pochotsa madzi otayira.
Kuthekera kwapadziko lonse lapansi kwa ACN kukuyerekeza pafupifupi mapaundi 10 biliyoni pachaka.Asia-Pacific ndiwopitilira 40 peresenti yake chifukwa chakukula kwamakampani omanga m'misika yomwe ikubwera monga China ndi India.Europe ndi dera lachiwiri lalikulu kutsatiridwa ndi North America potengera mphamvu zopangira.Msika wogulitsa ACN waphatikizidwa, ndipo ena mwa omwe amapanga INEOS Capital Limited, Ascend Performance Materials, AnQore ndi Mitsubishi Chemical Corporation.

Acrylonitrile imapangidwa ndi malonda ndi propylene ammoxidation, momwe propylene, ammonia, ndi mpweya zimakhudzidwa ndi chothandizira pabedi lamadzimadzi.Acrylonitrile imagwiritsidwa ntchito makamaka ngati co-monomer popanga acrylic ndi modacrylic fibers.Ntchito zikuphatikizapo kupanga mapulasitiki, zokutira pamwamba, nitrile elastomers, zotchinga resins, ndi zomatira.Ndi mankhwala apakatikati pakupanga mitundu yosiyanasiyana ya antioxidants, mankhwala, utoto, komanso yogwira ntchito pamwamba.
1. Acrylonitrile yopangidwa ndi polyacrylonitrile fiber, yomwe ndi acrylic fiber.
2. Acrylonitrile ndi butadiene akhoza kupangidwa ndi copolymerized kuti apange mphira wa nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized kukonzekera ABS utomoni.
4. Acrylonitrile hydrolysis imatha kupanga acrylamide, acrylic acid ndi esters ake.
