Ana samar da Acrylonitrile ta kasuwanci ta hanyar propylene ammoxidation, wanda propylene, ammonia, da iska ke amsawa ta hanyar mai kara kuzari a cikin gado mai ruwa.Ana amfani da Acrylonitrile da farko azaman co-monomer wajen samar da filaye na acrylic da modacrylic.Abubuwan da ake amfani da su sun haɗa da samar da robobi, rufin sama, nitrile elastomers, resins na shinge, da adhesives.Hakanan tsaka-tsakin sinadarai ne a cikin haɗakar antioxidants daban-daban, magunguna, rini, da aiki mai aiki.
1. Acrylonitrile sanya daga polyacrylonitrile fiber, wato acrylic fiber.
2. Acrylonitrile da butadiene za a iya copolymerized don samar da nitrile roba.
3. Acrylonitrile, butadiene, styrene copolymerized don shirya guduro ABS.
4. Acrylonitrile hydrolysis na iya samar da acrylamide, acrylic acid da esters.
Mafi akasarin fiber carbon na duniya an samo su ne daga PAN da aka yi ta amfani da ACN monomer na propylene da ammonia.ACN polymerized zuwa PAN ta hanyar haɗa shi tare da acrylic comonomers na filastik da kuma mai kara kuzari.Wannan tsarin samar da sinadarai gabaɗaya da tsarin jujjuyawa yana da rikitarwa, tsada da ƙarfin kuzari.Bugu da ari, samar da kilogiram 1 na fiber carbon yana buƙatar kilogiram 2 na PAN, wanda ke ba PAN ƙimar juzu'i na 50% kawai - da kuma babban sawun iskar gas.
