Taw qhia
3,4-difluorobenzotrifluoride yog cov organic compound nrog cov tshuaj formula C7H2F5. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
-Cov tsos mob: 3,4-difluorobenzotrifluoride yog cov kua tsis muaj xim.
- Melting point: -35 ° C
- Kub taw tes: 114 ° C
Qhov ceev: 1.52g / cm³
-Solubility: Nws yog soluble nyob rau hauv ntau cov organic solvents, xws li ethanol, ether thiab benzene.
Siv:
-3,4-difluorobenzotrifluoride feem ntau yog siv los ua cov kuab tshuaj rau cov organic synthesis tshuaj. Nws siab solubility thiab anhydrous xwm ua rau nws ib tug tseem ceeb daim ntawv thov nyob rau hauv cov organic synthesis.
-Nws tseem tuaj yeem siv los ua tus neeg saib xyuas qhov chaw thiab tus neeg saib xyuas.
Txoj kev:
-3,4-difluorobenzotrifluoride tuaj yeem tau txais los ntawm kev ua haujlwm 3,4-difluorophenyl hydrogen sulfide nrog barium trifluoride. Cov tshuaj tiv thaiv kab mob feem ntau yog nyob rau hauv lub xub ntiag ntawm magnesium chloride, cua sov rau ob peb teev, thiab tom qab ntawd kho qhov tshwm sim nruab nrab nrog cawv.
Cov ntaub ntawv kev nyab xeeb:
-3,4-difluorobenzotrifluoride yog cov organic sib xyaw ua ke, thiab kev nqus ntawm nws cov vapor yuav tsum zam.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv thaum siv.
-Nyob ntev los yog hnyav heev yuav ua rau muaj kev phom sij rau kev noj qab haus huv thiab tej zaum yuav ua rau qhov muag, ua pa thiab khaus tawv nqaij.
-hauv kev siv thiab khaws cia yuav tsum xyuam xim rau kev tiv thaiv hluav taws thiab tawg, tsis txhob sib cuag nrog cov oxidants muaj zog.
-Yog tias koj tsoo koj lub qhov muag yuam kev lossis tiv tauj koj cov tawv nqaij, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
