Taw qhia
Chlorofluorobenzene yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm chlorofluorobenzene:
Zoo:
Chlorofluorobenzene muaj qhov tshwj xeeb physicochemical zog, solubility thiab volatility. Nyob rau hauv chav tsev kub, nws ruaj khov, tab sis tuaj yeem cuam tshuam nrog cov oxidants muaj zog thiab muaj zog txo cov neeg ua haujlwm. Cov tshuaj chlorine thiab fluorine atoms nyob rau hauv nws cov molecule, chlorofluorobenzene muaj qee yam reactivity.
Siv:
Chlorofluorobenzene muaj ntau yam kev siv hauv kev lag luam. Chlorofluorobenzene kuj tuaj yeem siv los ua cov kuab tshuaj hauv kev sib txuas ntawm cov tshuaj organometallic thiab inks.
Txoj kev:
Kev npaj ntawm chlorofluorobenzene feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm chlorobenzene nrog hydrogen fluoride. Cov tshuaj tiv thaiv no yuav tsum tau ua nyob rau hauv lub xub ntiag ntawm catalysts, xws li zinc fluoride thiab hlau fluoride. Cov tshuaj tiv thaiv kab mob feem ntau ua tiav ntawm qhov kub thiab txias, nrog rau qhov kub ntawm 150-200 degrees Celsius.
Cov ntaub ntawv kev nyab xeeb: Chlorofluorobenzene ua rau khaus ntawm daim tawv nqaij thiab qhov muag, thiab kev sib cuag ncaj qha yuav tsum raug zam thaum kov. Thaum lub sijhawm ua haujlwm, kev ntsuas cua zoo yuav tsum tau ua kom tsis txhob nqus cov khoom. Chlorofluorobenzene yog cov khoom siv hluav taws xob thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov khoom siv hluav taws xob thiab qhov chaw kub kub. Thaum khaws cia, nws yuav tsum muab tso rau hauv qhov chaw txias, qhuav thiab zoo-ventilated, deb ntawm hluav taws thiab oxidants.
