Acrylonitrile 99.5%, CAS Nr .: 107-13-1, CH 2 TSI,
Acrylonitrile yog cov tshuaj lom neeg uas muaj cov pa roj carbon monoxide, thiab nws muaj cov khoom xws li volatile, kua, thiab tsis muaj xim, tau los ntawm kev sib txuas ntawm ob lub atoms, vinyl pawg, thiab nitrile, nws yog ib qho tshwj xeeb molecule uas pab ua polymerization kom tau macromolecule zoo li polyacrylonitrile. .Kev ua lag luam thoob ntiaj teb Acrylonitrile yuav tsum pom qhov kev loj hlob nruab nrab thaum lub sijhawm kwv yees.Cov xwm txheej zoo li kev siv ntau ntxiv hauv kev lag luam tsheb vim nws cov khoom siv thermoplastic txo qhov hnyav ntawm lub tsheb, uas tau kwv yees tias yuav ua rau muaj kev xav tau ntawm Acrylonitrile kev ua lag luam nyob rau lub sijhawm kwv yees.Tsis tas li ntawd, lub hauv paus tseem ceeb uas ua rau muaj kev loj hlob ntawm kev lag luam acrylonitrile yog nws cov kev siv ntau heev hauv kev tsim kho kev lag luam rau kev tsim cov hniav nyiaj hniav kub sab hauv, cov chaw nruab nrab, cov headliners, thiab lwm yam uas xav tias yuav nce qhov kev thov ntawm Acrylonitrile kev ua lag luam nyob rau lub sijhawm kwv yees.Tsis tas li ntawd, nce kev siv hauv cov khoom siv hluav taws xob thiab cov neeg siv khoom siv tau tsav lub ntiaj teb Acrylonitrile kev lag luam kev loj hlob nyob rau lub sijhawm kwv yees.Txawm li cas los xij, kev hloov pauv ntawm cov nqi ntawm cov khoom siv raw thiab cov teebmeem ntawm acrylonitrile tebchaw ntawm ib puag ncig, nrog rau cov tshuaj lom neeg thiab cov nplaim taws, txwv kev loj hlob ntawm kev lag luam acrylonitrile hauv lub sijhawm kwv yees.
Acrylonitrile yog siv ntau yam tshuaj xws li acrylonitrile butadiene styrene (ABS), acrylic fibers, styrene-acrylonitrile resins (SAR), nitrile roj hmab, thiab carbon fibers, thiab lwm yam.

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.
