Tlhaloso le Sebopeho sa Acrylonitrile
Ha re qaleng ka ho hlahisa acrylonitrile pele re fetela lihloohong tse ling.Acrylonitrile ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale CH2 CHCN.E khethiloe e le motsoako oa lintho tse phelang hobane feela o entsoe ka liathomo tsa carbon le hydrogen.Ka mokhoa o hlophisitsoeng, le ka lihlopha tse sebetsang (lihlopha tsa bohlokoa le tse khethollang tsa liathomo), acrylonitrile e na le tse peli tsa bohlokoa, alkene le nitrile.Alkene ke sehlopha se sebetsang se nang le carbon-carbon double bond, athe nitrile ke e nang le carbon-nitrogen triple bond.
Thepa ea Acrylonitrile
Kaha joale re se re tseba hore na acrylonitrile ke eng, ha re feteleng ho bua ka tse ling tsa thepa ea eona ea bohlokoa.Ha e rekoa ho bafani ba lik'hemik'hale, acrylonitrile hangata e tla e le mokelikeli o hlakileng, o se nang 'mala.Haeba e na le 'mala o mosehla ho eona, hangata sena se bolela hore e na le litšila' me mohlomong e tla hloka ho hloekisoa (ho hloekisa mokelikeli) pele e sebelisoa bakeng sa liphetoho tsa lik'hemik'hale le lintho tsa mofuta oo.Sebaka se belang sa Acrylonitrile se lekantsoe ka liteko ho ba likhato tse 77 tsa Celsius, tse batlang li le tlase bakeng sa mokelikeli oa tlhaho.Ka ntlha ena e tlase e belang, acrylonitrile ka linako tse ling e bitsoa motsoako o tsitsitseng, e leng se bolelang hore limolek'hule tsa acrylonitrile tsa mokelikeli li baleha habonolo mokhahlelong oa khase ebe lia fetoha mouoane.Ka lebaka lena, ke mohopolo o motle hore le ka mohla u se ke ua siea botlolo ea acrylonitrile e bulehile moeeng hobane e tla fetoha mouoane kapele.
Sebelisa
Tšebeliso e ka sehloohong ea acrylonitrile ke thepa e tala bakeng sa ho etsa li-acrylic le modacrylic fibers.Lisebelisoa tse ling tse kholo li kenyelletsa tlhahiso ea polasetiki (acrylonitrile-butadiene-styrene (ABS) le styrene-acrylonitrile (SAN)), liraba tsa nitrile, li-resin tsa nitrile barrier, adiponitrile le acrylamide.
Acrylonitrile e 'nile ea sebelisoa, ka motsoako le carbon tetrachloride, e le mosi bakeng sa ho sila phofo le lisebelisoa tsa ho lokisa lijo tsa likuku le koae e bolokiloeng.Leha ho le joalo, lihlahisoa tse ngata tse bolaeang likokoanyana tse nang le acrylonitrile li 'nile tsa tlosoa ka boithatelo ke bahlahisi.Hajoale, acrylonitrile hammoho le carbon tetrachloride e ngolisitsoe e le chefo e thibelang likokoana-hloko.51% ea tšebeliso ea United States ea acrylonitrile e ne e sebelisoa bakeng sa likhoele tsa acrylic, 18% bakeng sa ABS le SAN resin, 14% bakeng sa adiponitrile, 5% bakeng sa acrylamide le 3% bakeng sa nitrile elastomers.9% e setseng e ne e le ea litšebeliso tse fapaneng (Cogswell 1984).
