Taw qhia
M-chlorofluorobenzene yog ib qho organic compound.
Zoo:
- M-chlorofluorobenzene yog cov xim tsis muaj xim rau daj daj daj nrog cov ntxhiab tsw ntxhiab tsw.
- Nws muaj qhov ntom ntom ntom thiab yog soluble hauv ntau cov kuab tshuaj organic, xws li ethanol, ether, thiab lwm yam.
- Nws decomposes ntawm qhov kub thiab txias, ua rau cov pa phem.
Siv:
- Nws tuaj yeem siv los ua cov kuab tshuaj, tshuaj ntxuav tes thiab cov tshuaj rho tawm.
Txoj kev:
Muaj ob txoj hauv kev npaj tseem ceeb rau m-chlorofluorobenzene:
Txoj kev siv roj fluorine: cov roj fluorine tau dhau mus rau hauv cov tshuaj tiv thaiv sib xyaw ntawm chlorobenzene, thiab m-chlorofluorobenzene yog tsim los ntawm kev ua haujlwm ntawm catalyst.
Cov txheej txheem kev lag luam: cov tshuaj tiv thaiv deuteration tshwm sim nyob rau hauv lub xub ntiag ntawm ib tug catalyst los ntawm benzene thiab chloroform los tsim m-chlorofluorobenzene.
Cov ntaub ntawv kev nyab xeeb:
- M-chlorofluorobenzene yog cov kua tsis hloov pauv uas yog cov nplaim taws thiab tuaj yeem ua rau hluav taws kub thaum raug hluav taws kub los yog kub.
- Nws yog ib yam tshuaj lom uas yuav ua rau khaus thiab puas yog tias nws nkag mus rau ntawm daim tawv nqaij lossis yog nqus tau.
- Thaum siv lossis npaj m-chlorofluorobenzene, ua raws li cov txheej txheem kev nyab xeeb nruj thiab siv cov kev tiv thaiv tsim nyog, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg.
