Acrylonitrile rau PAN

Lus piav qhia luv luv:

Cov acrylonitrile yog cov xim tsis muaj xim rau daj daj daj thiab cov kua dej tsis haum uas yog soluble hauv dej thiab feem ntau cov organic solvents xws li acetone, benzene, carbon tetrachloride, ethyl acetate, thiab toluene.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.

Acrylonitrile rau PAN,
Acrylonitrile rau Polyacrylonitrile, Acrylonitrile rau polyacrylonitrile fiber ntau,

Polyacrylonitrile (PAN) yog ib qho hluavtaws polymer nrog cov qauv linear (C3H3N) n.Txawm hais tias nws yog thermoplastic nws tsis yaj nyob rau hauv ib txwm muaj mob, vim nws degrades ua ntej melting ntawm siab tshaj 300 ° C.Yuav luag tag nrho cov PAN resins yog copolymers ua los ntawm kev sib xyaw ntawm monomers, nrog acrylonitrile ua cov khoom tseem ceeb.Nws yog ntau yam polymer siv los tsim ntau yam khoom, suav nrog fibers rau textiles, ultra-filtration membranes, hollow fibers rau thim rov qab osmosis, thiab lwm yam. PAN fibers yog cov precursor nyob rau hauv zus tau tej cov high-zoo carbon fibers.

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.
