Inkcazo kunye neSakhiwo se-Acrylonitrile
Masiqale ngokwazisa i-acrylonitrile ngaphambi kokuba sidlulele kwezinye izihloko.I-Acrylonitrile yi-organic compound ene-chemical formula CH2 CHCN.Ihlelwa njenge-organic compound ngenxa yokuba ubukhulu becala yenziwe nge-carbon kunye ne-athomu ye-hydrogen.Ngokwesakhiwo, kunye namaqela asebenzayo (amaqela abalulekileyo kunye ahlukeneyo e-athomu), i-acrylonitrile inezimbini ezibalulekileyo, i-alkene kunye ne-nitrile.I-alkene liqela elisebenzayo eliqulethe i-carbon-carbon bond double, ngelixa i-nitrile iqulethe i-carbon-nitrogen bond triple.
Iipropati ze-Acrylonitrile
Ngoku ukuba siyazi ukuba yintoni i-acrylonitrile, makhe siqhubele phambili ekuthetheni ngezinye zeempawu zayo ezibaluleke kakhulu.Xa kuthengwa kubaboneleli beekhemikhali, i-acrylonitrile idla ngokuza njengolwelo olucacileyo, olungenambala.Ukuba inombala otyheli kuyo, oku kuthetha ukuba iqulethe ukungcola kwaye kuya kufuneka ukuba igalelwe (kucocwa ulwelo) phambi kokuba isetyenziswe kwimichiza nezinto ezilolo hlobo.Iqondo lokubila le-Acrylonitrile lilinganiswe ngokomfuniselo laya kutsho kuma-77 degrees celcius, nelisezantsi noko kulwelo oluphilayo.Ngalo nqanaba lokubilisa eliphantsi i-acrylonitrile ngamanye amaxesha ibizwa ngokuba yi-compound eguqukayo, oku kuthetha ukuba i-molecule ye-acrylonitrile yolwelo ibaleka ngokukhawuleza kwisigaba segesi kwaye ikhuphe.Ngesi sizathu, luluvo olulungileyo ukuba ungaze ushiye ibhotile ye-acrylonitrile ivulekele emoyeni kuba iya kuphuma ngumphunga ngokukhawuleza.
Sebenzisa
Ukusetyenziswa okuphambili kwe-acrylonitrile kufana nemathiriyeli ekrwada yokwenziwa kwe-acrylic kunye ne-modacrylic fibers.Olunye usetyenziso olukhulu lubandakanya ukuveliswa kweeplastiki (i-acrylonitrile-butadiene-styrene (ABS) kunye ne-styrene-acrylonitrile (SAN)), iirubha ze-nitrile, i-nitrile barrier resins, i-adiponitrile kunye ne-acrylamide.
I-Acrylonitrile isetyenzisiwe, kumxube we-carbon tetrachloride, njenge-fumigant yokugaya umgubo kunye nezixhobo zokulungisa ukutya kwi-bakery kunye necuba eligciniweyo.Nangona kunjalo, uninzi lweemveliso ze-pesticide eziqukethe i-acrylonitrile ziye zahoxiswa ngokuzithandela ngabavelisi.Okwangoku, i-acrylonitrile idibene ne-carbon tetrachloride ibhaliswe njengesibulali-zinambuzane esithintelweyo.I-51% ye-United States yokusetyenziswa kwe-acrylonitrile yayisetyenziselwa iifayili ze-acrylic, i-18% ye-ABS kunye ne-SAN resins, i-14% ye-adiponitrile, i-5% ye-acrylamide kunye ne-3% ye-nitrile elastomers.I-9% eseleyo yayiyeyokusetyenziswa kwizinto ezahlukeneyo (Cogswell 1984).
