Taw qhia
2,4-Difluorobromobenzene yog ib qho organic compound. Nws yog xim tsis muaj xim rau daj ntseg daj kua nrog ib tug pungent tsw. Cov hauv qab no yog cov lus piav qhia ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2,4-difluorobromobenzene:
Zoo:
2,4-Difluorobromobenzene yog cov khoom siv hluav taws xob uas tuaj yeem tsim cov nplaim hluav taws lossis tawg sib xyaw nrog huab cua. Nws yog corrosive rau qee cov hlau.
Siv:
2,4-Difluorobromobenzene feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis. Hauv thaj chaw ntawm cov tshuaj tua kab, nws yog siv los ua tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
2,4-Difluorobromobenzene feem ntau yog npaj los ntawm kev hloov cov tshuaj tiv thaiv. Ib txoj kev npaj ntau yog ua kom cov tshuaj bromobenzene nrog poov tshuaj fluoride nyob rau hauv acidic tej yam kev mob los tsim 2,4-dibromobenzene, thiab ces fluorinate nyob rau hauv lub xub ntiag ntawm ib tug fluorinating neeg sawv cev kom tau 2,4-difluorobromobenzene.
Cov ntaub ntawv kev nyab xeeb:
2,4-Difluorobromobenzene yog ib yam khoom organic uas muaj qee yam toxicity. Nws muaj kev cuam tshuam rau ntawm daim tawv nqaij, qhov muag, thiab cov mucous daim nyias nyias thiab yuav tsum tau yaug nrog dej tam sim ntawd tom qab kev sib cuag. Kev nqus pa ntawm nws cov vapors yuav tsum zam thaum siv thiab ua kom muaj cua txaus yuav tsum tau ua kom ntseeg tau. Thaum khaws cia thiab tuav, yuav tsum tau saib xyuas kom tsis txhob muaj hluav taws xob thiab hluav taws xob zoo li qub. Yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb uas tsim nyog thiab cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav. Thaum tuav 2,4-difluorobromobenzene, cov kev cai hauv zos yuav tsum tau ua raws li thiab cov pov tseg yuav tsum muab pov tseg kom raug.
