Taw qhia
O-difluorobenzene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm o-difluorobenzene:
Zoo:
- Cov tsos mob: O-difluorobenzene yog cov kua tsis muaj xim lossis dawb siv lead ua.
- Solubility: O-difluorobenzene yog soluble hauv cov kuab tshuaj organic xws li cawv, ethers thiab benzene.
Siv:
- O-difluorobenzene tuaj yeem siv los ua cov khoom pib thiab nruab nrab hauv cov organic synthesis, thiab yog siv dav hauv kev lag luam tshuaj, tshuaj tua kab thiab tshuaj pleev xim.
- Nws kuj tseem siv tau los ua ib qho ntxiv hauv cov txheej txheem, cov kuab tshuaj thiab cov roj nplua nyeem.
- O-difluorobenzene kuj tseem siv tau hauv kev lag luam hluav taws xob, xws li cov khoom siv ua kua siv lead ua kua.
Txoj kev:
- Muaj ob txoj hauv kev tseem ceeb rau kev npaj o-difluorobenzene: cov tshuaj tiv thaiv ntawm fluorine compounds nrog benzene thiab xaiv cov tshuaj fluorination ntawm fluorinated benzene.
- Cov tshuaj tiv thaiv ntawm fluorine tebchaw nrog benzene muaj ntau, thiab o-difluorobenzene tuaj yeem tau los ntawm fluorination ntawm chlorobenzene los ntawm cov roj fluorine.
- Kev xaiv fluorination ntawm fluorinated benzene yuav tsum tau siv cov tshuaj fluorinating reagents rau kev sib txuas.
Cov ntaub ntawv kev nyab xeeb:
- Kev raug o-difluorobenzene tuaj yeem ua rau khaus tawv nqaij, qhov muag thiab ua pa, thiab yuav tsum tau ceev faj.
- Hnav tsom iav tiv thaiv, hnab looj tes thiab khaub ncaws ua haujlwm thaum siv o-difluorobenzene, thiab tuav lub qhov cua kom zoo.
- Khaws kom deb ntawm qhov hluav taws kub thiab kub, thiab khaws cia rau hauv qhov chaw txias, qhuav.
- Ua ntej siv lossis tuav o-difluorobenzene, nyeem thiab ua raws li cov lus qhia txog kev nyab xeeb.
