Acrylonitrile (ACN), cov organic compound, yog cov kua tsis muaj xim thiab pob tshab uas ua los ntawm propylene thiab ammonia.Nws yog reactive thiab lom nyob rau hauv cov xwm;Txawm li cas los xij, nws paub txog nws lub zog thiab kav ntev.
Nws yog monomer uas tsim cov polyacrylonitrile, homopolymer, copolymer xws li acrylic fibers, acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN), acrylonitrile styrene acrylate (ASA) thiab lwm yam roj hmab xws li acrylonitrile (BR) loj kawg-neeg siv.Ntawm cov neeg siv kawg daim ntawv thov, ABS thermoplastic pab txhawb rau ntau tshaj 35 feem pua ntawm tag nrho cov kev thov ua raws li acrylic fibers nrog kwv yees qhov xav tau ntawm 27 feem pua.Kwv yees li ob peb xyoos dhau los, acrylic fibers suav nrog qhov kev xav tau loj, tab sis ABS tau maj mam thiab tsis tu ncua tau txais txiaj ntsig zoo nyob rau sab nraum qab ntawm nws lub zog, ua haujlwm ntev thiab kub ua haujlwm uas yuav tsum tau muaj nyob rau hauv ntau daim ntawv sau npe.Ntau yam khoom siv (tub yees, chav ua noj, thiab lwm yam), hluav taws xob thiab hluav taws xob, thiab kev lag luam tsheb yog cov neeg siv khoom loj ntawm ABS.Acrylic fibers tau maj mam hloov los ntawm polyester fibers dua tus nqi qis thiab rov ua dua yooj yim dua.Acrylonitrile kuj tseem siv los ua ib qho nruab nrab los tsim Acrylamide, uas yog kwv yees li 15 feem pua ntawm tag nrho cov kev thov, uas tsim cov polyacrylamide (PAM) siv hauv kev siv dej khib nyiab.
Lub peev xwm tsim khoom thoob ntiaj teb ntawm ACN yog kwv yees li ntawm 10 billion phaus ib xyoos ib zaug.Asia-Pacific suav txog ntau dua 40 feem pua ntawm nws vim kev loj hlob hauv kev tsim kho kev lag luam hauv cov lag luam tawm tshiab xws li Tuam Tshoj thiab Is Nrias teb.Teb chaws Europe yog lub thib ob loj tshaj plaws cheeb tsam raws li North America nyob rau hauv cov nqe lus ntawm kev tsim muaj peev xwm.Lub khw muag khoom ACN tau sib sau ua ke, nrog qee tus neeg tsim khoom loj yog INEOS Capital Limited, Ascend Performance Materials, AnQore thiab Mitsubishi Chemical Corporation.

Khoom siv
Acrylonitrile yog ua lag luam los ntawm propylene ammoxidation, nyob rau hauv uas propylene, ammonia, thiab cua yog reacted los ntawm catalyst nyob rau hauv ib tug fluidized txaj.Acrylonitrile feem ntau yog siv los ua co-monomer hauv kev tsim cov acrylic thiab modacrylic fibers.Kev siv muaj xws li kev tsim cov yas, txheej txheej, nitrile elastomers, barrier resins, thiab cov nplaum.Nws kuj yog ib qho tshuaj nruab nrab hauv cov synthesis ntawm ntau yam antioxidants, tshuaj, dyes, thiab nto-active.
1. Acrylonitrile ua los ntawm polyacrylonitrile fiber, uas yog acrylic fiber.
2. Acrylonitrile thiab butadiene tuaj yeem ua copolymerized los tsim cov roj hmab nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized los npaj ABS resin.
4. Acrylonitrile hydrolysis tuaj yeem tsim acrylamide, acrylic acid thiab nws cov esters.
