Ethylene (C2H4)

Technical parameters

Nyob rau hauv ib txwm muaj xwm txheej, ethylene yog ib qho tsis muaj xim, me ntsis ntxhiab tsw ntxhiab roj nrog qhov ceev ntawm 1.178g / L, uas yog me ntsis ntom dua huab cua.Nws yuav luag insoluble hauv dej, tsis yooj yim soluble hauv ethanol, thiab me ntsis soluble hauv ethanol, ketones, thiab benzene.Soluble nyob rau hauv ether, yooj yim soluble nyob rau hauv organic solvents xws li carbon tetrachloride.Ethyleneyog ib qho ntawm cov khoom siv tshuaj lom neeg nrog cov khoom siv ntau tshaj plaws hauv lub ntiaj teb.Kev lag luam ethylene yog lub hauv paus ntawm kev lag luam petrochemical.Ethylene cov khoom lag luam suav txog ntau dua 75% ntawm cov khoom siv petrochemical thiab tuav txoj haujlwm tseem ceeb hauv kev lag luam hauv tebchaws.Lub ntiaj teb tau suav tias kev tsim khoom ethylene yog ib qho tseem ceeb ntsuas ntsuas kev loj hlob ntawm ib lub teb chaws kev lag luam petrochemical.Ethylene yog ib qho tseem ceeb ntawm cov organic chemical yooj yim raw cov ntaub ntawv, feem ntau yog siv nyob rau hauv zus tau tej cov polyethylene, ethylene propylene roj hmab, polyvinyl chloride, thiab lwm yam. Ethylene yog ib tug ntawm cov tseem ceeb raw cov ntaub ntawv rau petrochemical kev lag luam.Hais txog cov khoom siv hluavtaws, nws tau siv dav hauv kev tsim cov polyethylene, vinyl chloride, thiab lwm yam.;Nyob rau hauv cov nqe lus ntawm organic synthesis, nws yog dav siv nyob rau hauv lub synthesis ntawm ethanol, ethylene oxide, ethylene glycol, acetaldehyde, thiab propylene.Ntau yam ntawm cov organic synthesis raw cov ntaub ntawv xws li aldehydes thiab lawv cov derivatives;los ntawm halogenation, nws muaj peev xwm tsim chloroethylene, chloroethane, bromoethane, thiab lwm yam. Ethylene kuj tsuas yog siv raws li ib tug qauv roj rau analytical instruments nyob rau hauv petrochemical qhauj;siv los ua ib puag ncig tus phooj ywg ripening roj rau cov txiv hmab txiv ntoo xws li txiv kab ntxwv, txiv kab ntxwv, txiv tsawb, thiab lwm yam.;siv nyob rau hauv synthesis ntawm cov tshuaj thiab high-tech cov ntaub ntawv;siv los tsim cov iav tshwj xeeb rau kev lag luam tsheb;siv los ua cov tub yees, tshwj xeeb tshaj yog nyob rau hauv LNG liquefaction nroj tsuag.Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias.Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.Qhov kub cia yuav tsum tsis pub tshaj 30 ° C.Nws yuav tsum tau muab cais los ntawm oxidants thiab halogens, thiab tsis txhob sib xyaw cia.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua.Nws yog txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas nquag ua rau lub txim taws.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.
