Taw qhia
2,4-Dinitrofluorobenzene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- 2,4-Dinitrofluorobenzene yog cov khoom uas tsis muaj xim rau lub teeb daj crystalline cov ntaub ntawv.
- Nyob rau hauv chav tsev kub, nws yog insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv organic solvents xws li ether thiab dimethylformamide.
- Nws yog ib qho hluav taws xob sib xyaw ua ke thiab yuav tsum tau ua tib zoo saib xyuas.
Siv:
- 2,4-Dinitrofluorobenzene feem ntau yog siv rau hauv kev tsim cov xim daj hauv cov khoom tawg thiab kev lag luam pyrotechnic.
- Nws kuj yog siv los ua ib qho nruab nrab hauv dyes thiab pigments, thiab muaj qee yam kev siv hauv kev tshuaj xyuas tshuaj thiab cov organic synthesis.
Txoj kev:
- 2,4-Dinitrofluorobenzene tuaj yeem tau txais los ntawm nitrification ntawm p-chlorofluorobenzene.
- Txoj kev npaj tshwj xeeb tuaj yeem ua tiav los ntawm cov tshuaj tiv thaiv ntawm nitric acid thiab nyiaj nitrate, concentrated nitric acid thiab thionyl fluoride, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
- 2,4-Dinitrofluorobenzene yog cov tshuaj lom neeg muaj peev xwm carcinogenic thiab teratogenic txaus ntshai.
- Cov hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm.
- Tsis txhob kov ntawm daim tawv nqaij, qhov muag, thiab ua pa.
- Cov khib nyiab yuav tsum tau muab pov tseg raws li cov kev cai ib puag ncig thiab yuav tsum tsis txhob muab tso rau hauv dej lossis ib puag ncig.
