Taw qhia
Qhia 1-Chloro-1-fluoroethene, tseem hu ua chlorofluoroethylene lossis CFC-133a, yog cov roj tsis muaj xim nrog cov ntxhiab tsw. Lub compound, uas muaj cov tshuaj formula C2H2ClF, yog dav siv nyob rau hauv zus tau tej cov vinyl chloride, lub ntsiab tivthaiv ntawm polyvinyl chloride (PVC), ntau yam yas lug siv nyob rau hauv kev tsim kho kev lag luam, ntim thiab cov khoom siv kho mob.
1-Chloro-1-fluoroethylene feem ntau yog siv los ua ib qho nruab nrab hauv kev tsim khoom ntawm lwm cov tebchaw, suav nrog cov tub yees, cov kuab tshuaj thiab cov tshuaj agrochemicals. Nws kuj yog siv los ua cov nplaim hluav taws xob ntxiv hauv cov yas thiab cov txheej txheem.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 1-Chloro-1-fluoroethene yog nws qhov kub tsis tshua muaj kub ntawm -57.8 ° C, uas ua rau nws muaj qhov zoo tshaj plaws rau kev siv tub yees. Nws cov solubility siab nyob rau hauv dej ua rau nws haum rau siv nyob rau hauv hluav taws tua hluav taws thiab ua ib tug tu neeg sawv cev nyob rau hauv electronics thiab semiconductor industries.
Txawm li cas los xij, 1-Chloro-1-fluoroethene yuav tsum tau ua tib zoo saib xyuas vim tias nws yog cov nplaim taws heev thiab tuaj yeem ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv. Kev cuam tshuam rau qhov siab tuaj yeem ua rau lub qhov muag, qhov ntswg thiab caj pas thiab, thaum mob hnyav, ua rau muaj teeb meem ua pa thiab puas hlwb.
Thaum tuav 1-Chloro-1-fluoroethene, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj txog kev nyab xeeb, suav nrog kev siv cov khaub ncaws tiv thaiv thiab khoom siv xws li hnab looj tes, tsom iav, thiab lub tshuab ua pa. Nws tseem yog ib qho tseem ceeb uas yuav tsum khaws cia rau hauv qhov chaw uas muaj qhov cua zoo kom deb ntawm qhov chaw hluav taws kub lossis cua sov.
1-Chloro-1-fluoroethylene yog npaj los ntawm reacting vinyl chloride los yog ethylene nrog hydrogen chloride thiab hydrogen fluoride nyob rau hauv lub xub ntiag ntawm ib tug catalyst. Nws los ntawm ntau qib thiab tuaj yeem yuav hauv ntau lossis ntim raws li cov roj compressed lossis kua.
Hauv cov ntsiab lus, 1-Chloro-1-fluoroethene yog cov tshuaj muaj txiaj ntsig zoo nrog ntau hom kev siv hauv kev lag luam chemical, plastics thiab tub yees. Txawm li cas los xij, nws yuav tsum tau saib xyuas thiab ntsuas kev nyab xeeb kom zoo los tiv thaiv kev phom sij thiab ua kom muaj kev noj qab haus huv ntawm tib neeg thiab ib puag ncig.
