Tsanangudzo uye Chimiro cheAcrylonitrile
Ngatitangei nekusuma acrylonitrile tisati taenda kune dzimwe misoro.Acrylonitrile is organic compound ine kemikari formula CH2 CHCN.Inotsanangurwa semusanganiswa wehupenyu nekuda kwekuti kazhinji inoumbwa nekabhoni uye maatomu ehydrogen.Zvimiro, uye maererano nemapoka anoshanda (akakosha uye akasiyana mapoka emaatomu), acrylonitrile ine maviri akakosha, alkene uye nitrile.An alkene iboka rinoshanda rine carbon-carbon double bond, nepo nitrile imwe ine carbon-nitrogen triple bond.
Zvivakwa zveAcrylonitrile
Iye zvino zvatave kujairana nei acrylonitrile, ngatifambei mukutaura nezve zvimwe zvezvayo zvakanyanya kukosha.Kana inotengwa kubva kune vatengesi vemakemikari, acrylonitrile inowanzouya semvura yakachena, isina ruvara.Kana iine ruvara rweyero pairi, izvi zvinowanzoreva kuti ine tsvina uye ingangoda kunyungudutswa (kuchenesa mvura) isati yashandiswa kugadzirisa kemikari uye zvinhu zverudzi irworwo.Acrylonitrile's boiling point yakayerwa nekuyedza kuita 77 degrees celsius, iyo yakati dzikai pamvura yeorganic.Neiyi nzvimbo yakaderera yekubikira acrylonitrile dzimwe nguva inodaidzwa semushonga unoshanduka, izvo zvinoreva kuti mvura acrylonitrile mamorekuru anobuda nyore muchikamu chegasi uye anobuda.Nechikonzero ichi, ipfungwa yakanaka kusambosiya bhodhoro re acrylonitrile rakavhurika kumhepo nekuti rinobuda nekukurumidza.
Shandisa
Iko kushandiswa kwekutanga kweacrylonitrile kwakafanana neyakagadziriswa yekugadzira acrylic uye modacrylic fibers.Kumwe kushandiswa kukuru kunosanganisira kugadzirwa kwemapurasitiki (acrylonitrile-butadiene-styrene (ABS) uye styrene-acrylonitrile (SAN)), nitrile rubber, nitrile barrier resins, adiponitrile uye acrylamide.
Acrylonitrile yakashandiswa, mumusanganiswa nekabhoni tetrachloride, sefumigant yekugaya hupfu uye bhekeri kugadzira chikafu uye yefodya yakachengetwa.Zvisinei, mishonga yakawanda yemishonga ine acrylonitrile yakabviswa nekuzvidira nevagadziri.Parizvino, acrylonitrile yakasanganiswa nekabhoni tetrachloride inonyoreswa semushonga wekushandisa zvipembenene.51% yeUnited States inoshandiswa yeacrylonitrile yakashandiswa acrylic fibers, 18% yeABS neSAN resins, 14% yeadiponitrile, 5% ye acrylamide uye 3% ye nitrile elastomers.Iyo yakasara 9% yaive yekushandiswa kwakasiyana (Cogswell 1984).
