Ma'anar da Tsarin Acrylonitrile
Bari mu fara da gabatar da acrylonitrile kafin mu ci gaba zuwa wasu batutuwa.Acrylonitrile wani fili ne na kwayoyin halitta wanda ke da dabarar sinadarai CH2 CHCN.An lasafta shi azaman fili mai gina jiki kawai saboda yawanci ya ƙunshi carbon da hydrogen atom.A tsari, kuma dangane da ƙungiyoyi masu aiki (ƙungiyoyi masu mahimmanci da rarrabewa na atoms), acrylonitrile yana da mahimmanci guda biyu, alkene da nitrile.Alkene rukuni ne mai aiki wanda ya ƙunshi haɗin carbon-carbon ninki biyu, yayin da nitrile shine wanda ya ƙunshi haɗin carbon-nitrogen sau uku.
Abubuwan da ke cikin Acrylonitrile
Yanzu da muka saba da abin da acrylonitrile yake, bari mu matsa zuwa magana game da wasu mahimman kaddarorin sa.Lokacin da aka saya daga masu samar da sinadarai, acrylonitrile yakan zo a matsayin ruwa mai tsabta, marar launi.Idan yana da launin rawaya a gare shi, wannan yawanci yana nufin cewa yana ɗauke da ƙazanta kuma yana iya buƙatar a distilled (tsarkake ruwa) kafin a yi amfani da shi don halayen sinadarai da abubuwan wannan yanayin.An auna ma'aunin tafasar Acrylonitrile a matsayin gwaji a matsayin digiri 77 na ma'aunin celcius, wanda ke da ɗan ƙasa kaɗan ga ruwa mai ƙarfi.Tare da wannan ƙananan tafasar acrylonitrile wani lokaci ana kiranta da wani fili mai canzawa, wanda ke nufin cewa kwayoyin acrylonitrile na ruwa suna tserewa cikin hanzarin gas kuma su ƙafe.Saboda wannan dalili, yana da kyau a taɓa barin kwalban acrylonitrile a buɗe zuwa iska domin zai ƙafe da sauri.
Amfani
Babban amfani da acrylonitrile shine a matsayin albarkatun kasa don kera filaye na acrylic da modacrylic.Sauran manyan abubuwan amfani sun haɗa da samar da robobi (acrylonitrile-butadiene-styrene (ABS) da styrene-acrylonitrile (SAN)), rubbers nitrile, nitrile barrier resins, adiponitrile da acrylamide.
An yi amfani da Acrylonitrile, a cikin cakuda da carbon tetrachloride, a matsayin fumigant don niƙa fulawa da kayan aikin sarrafa abinci na burodi da kuma don sigari da aka adana.Koyaya, yawancin samfuran magungunan kashe qwari masu ɗauke da acrylonitrile an cire su da son rai daga masana'antun.A halin yanzu, acrylonitrile a hade tare da carbon tetrachloride an yi rajista azaman ƙayyadaddun maganin kashe kwari.51% na amfani da acrylonitrile na Amurka an yi amfani dashi don acrylic fibers, 18% na ABS da resin SAN, 14% don adiponitrile, 5% don acrylamide da 3% don nitrile elastomers.Sauran kashi 9% na amfani daban-daban ne (Cogswell 1984).
