Ethylene (C2H4)

Xuduudaha farsamada

Duruufaha caadiga ah, ethylene waa gaas aan midab lahayn, waxyar ur leh oo cufan ah 1.178g/L, kaas oo xoogaa cufan ka yar hawada.Waxay ku dhowdahay inaan lagu milmi karin biyaha, oo aan si dhib leh ugu milmin ethanol, iyo in yar oo ku milma ethanol, ketones, iyo benzene., Ku milmay ether, si fudud ugu milmi kara dareerayaasha organic sida tetrachloride carbon.Ethylenewaa mid ka mid ah wax soo saarka kiimikaad ee leh wax soo saarka ugu weyn adduunka.Warshadaha ethylene waa udub dhexaadka warshadaha petrochemical.Badeecadaha Ethylene waxay ka badan yihiin 75% badeecooyinka petrochemical waxayna ku jiraan boos muhiim ah dhaqaalaha qaranka.Dunidu waxay u tixgalisay wax-soo-saarka ethylene mid ka mid ah tilmaamayaasha muhiimka ah si loo cabbiro heerka horumarinta warshadaha batroolka ee dalka.Ethylene waa walxo muhiim ah oo kiimiko ah oo dabiici ah, oo inta badan loo isticmaalo soosaarka polyetylen, caag ethylene propylene, chloride polyvinyl, iwm.Marka la eego qalabka synthetic, waxaa si ballaaran loo isticmaalaa soo saarista polyetylen, chloride vinyl, iwm.Marka la eego isku-dhafka dabiiciga ah, waxaa si ballaaran loo isticmaalaa isku-dhafka ethanol, ethylene oxide, ethylene glycol, acetaldehyde, iyo propylene.Noocyada kala duwan ee alaabta ceeriin ee aasaasiga ah ee aasaasiga ah sida aldehydes iyo kuwa ka soo jeeda;iyada oo loo marayo halogenation, waxay soo saari kartaa chlorethylene, chloroethane, bromoethane, iwm.loo isticmaalo sidii gaas bisil oo deegaanka u wanaagsan oo loogu talagalay miraha sida liinta xuddunta, tangerines, muuska, iwm.;loo isticmaalo isku dhafka daawooyinka iyo qalabka farsamada sare;loo isticmaalo soo saarista dhalo gaar ah oo loogu talagalay warshadaha baabuurta;loo isticmaalo qaboojiye ahaan, Gaar ahaan dhirta Liquefaction LNG.Ka taxadar kaydinta: Ku kaydi bakhaar qabow oo hawo leh.Ka fogow dabka iyo ilaha kulaylka.Heerkulka kaydinta waa inuusan dhaafin 30 ° C.Waa in si gooni ah loo kaydiyaa oksidaant-yada iyo halogen-yada, lagana fogaado kaydinta isku dhafan.Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.Waa mamnuuc in la isticmaalo qalabka farsamada iyo qalabka u nugul dhinbiilka.Aagga kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdegga ah ee daadsan.
