Taw qhia
2,6-Difluorotoluene yog cov organic compound. Nws yog cov kua uas tsis muaj xim uas muaj cov ntxhiab tsw muaj zog. Cov hauv qab no yog cov lus qhia ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2,6-difluorotoluene:
Zoo:
- Soluble: Soluble nyob rau hauv non-polar solvents xws li ether thiab benzene
Siv:
- 2,6-Difluorotoluene feem ntau yog siv los ua cov khoom siv raw rau tshuaj tua kab thiab antioxidants. Nws tuaj yeem siv rau hauv kev tsim cov tshuaj tua kab, fungicides, thiab tshuaj ntsuab.
- Nws kuj tseem siv tau los ua ib qho nruab nrab hauv cov organic synthesis thiab muaj cov ntawv thov tseem ceeb hauv kev lag luam tshuaj thiab tshuaj.
Txoj kev:
- Kev npaj ntawm 2,6-difluorotoluene tuaj yeem tau los ntawm fluorination ntawm toluene. Ib txoj hauv kev yog siv hydrogen fluoride (HF) thiab difluorochloromethane (Freon 21) ua cov tshuaj tiv thaiv, catalyzed los ntawm tooj liab chloride (CuCl).
Cov ntaub ntawv kev nyab xeeb:
- 2,6-Difluorotoluene yog khaus thiab lom. Kev sib cuag nrog daim tawv nqaij, qhov muag, lossis kab mob ua pa yuav ua rau khaus thiab tsis xis nyob. Cov cuab yeej tiv thaiv tsim nyog xws li tsom iav kev nyab xeeb, hnab looj tes, thiab lub tshuab ua pa yuav tsum hnav thaum siv.
- Thaum lub sij hawm cia thiab tuav, kev sib cuag nrog cov oxidants muaj zog thiab muaj zog acids yuav tsum raug zam kom tsis txhob muaj kev phom sij txaus ntshai.
-Thaum muaj qhov dej xau, kev ntsuas tsim nyog yuav tsum tau muab tshem tawm tam sim ntawd txhawm rau tiv thaiv kev kis tus kabmob mus rau ib puag ncig.
- 2,6-difluorotoluene yuav tsum tsis txhob nyob rau hauv kev sib cuag nrog qhov hluav taws kub qhov chaw, nws yog flammable, thiab yuav tsum tau ceev kom deb ntawm qhov hluav taws kub qhov chaw thiab kub kub.
