Tanthauzo ndi Kapangidwe ka Acrylonitrile
Tiyeni tiyambe ndi kufotokoza acrylonitrile tisanapite ku nkhani zina.Acrylonitrile ndi organic pawiri yomwe ili ndi mankhwala formula CH2 CHCN.Imatchedwa kuti organic compound chifukwa chakuti imakhala ndi maatomu a carbon ndi hydrogen.Mwadongosolo, komanso potengera magulu ogwira ntchito (magulu ofunikira komanso apadera a ma atomu), acrylonitrile ili ndi ziwiri zofunika, alkene ndi nitrile.An alkene ndi gulu logwira ntchito lomwe lili ndi carbon-carbon double bond, pamene nitrile ndi imodzi yomwe imakhala ndi carbon-nitrogen triple bond.
Katundu wa Acrylonitrile
Tsopano popeza tadziwa kuti acrylonitrile ndi chiyani, tiyeni tikambirane zina mwazinthu zake zofunika kwambiri.Ikagulidwa kwa ogulitsa mankhwala, acrylonitrile nthawi zambiri imabwera ngati madzi omveka bwino, opanda mtundu.Ngati ili ndi utoto wonyezimira, izi zikutanthauza kuti ili ndi zonyansa ndipo iyenera kutayidwa (kuyeretsa madzi) isanagwiritsidwe ntchito pakupanga mankhwala ndi zinthu zamtunduwu.Kuwira kwa Acrylonitrile kwayesedwa moyesera kukhala madigiri 77 Celsius, komwe kumakhala kotsika pang'ono pamadzi achilengedwe.Ndi otsika kuwira mfundo acrylonitrile nthawi zina amatchedwa kosakhazikika pawiri, kutanthauza kuti madzi acrylonitrile mamolekyu mosavuta kuthawira mu gasi gawo ndi nthunzi.Pazifukwa izi, ndibwino kuti musasiye botolo la acrylonitrile lotseguka m'mlengalenga chifukwa limatuluka nthunzi mwachangu.
Gwiritsani ntchito
Ntchito yaikulu ya acrylonitrile ndi monga zopangira popanga acrylic ndi modacrylic ulusi.Ntchito zina zazikuluzikulu zimaphatikizapo kupanga mapulasitiki (acrylonitrile-butadiene-styrene (ABS) ndi styrene-acrylonitrile (SAN)), mphira wa nitrile, nitrile barrier resins, adiponitrile ndi acrylamide.
Acrylonitrile yakhala ikugwiritsidwa ntchito, mu osakaniza ndi carbon tetrachloride, monga fumigant kwa ufa mphero ndi bakery zipangizo pokonza chakudya ndi kusungidwa fodya.Komabe, mankhwala ambiri ophera tizilombo okhala ndi acrylonitrile achotsedwa mwaufulu ndi opanga.Pakalipano, acrylonitrile pamodzi ndi carbon tetrachloride amalembedwa ngati mankhwala ophera tizilombo.51% ya United States yogwiritsira ntchito acrylonitrile inagwiritsidwa ntchito pazitsulo za acrylic, 18% ya ABS ndi SAN resins, 14% ya adiponitrile, 5% ya acrylamide ndi 3% ya nitrile elastomers.9% yotsalayo inali yogwiritsidwa ntchito mosiyanasiyana (Cogswell 1984).
