Taw qhia
2,6-Difluorobenzonitrile, tseem hu ua 2,6-difluorobenzonitrile, yog cov 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:
- Cov tsos mob: 2,6-Difluorobenzonitrile yog cov kua tsis muaj xim lossis dawb siv lead ua.
- Solubility: Soluble hauv cov kuab tshuaj organic.
Siv:
- 2,6-Difluorobenzonitrile feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, piv txwv li cov khoom pib rau kev tsim khoom ntawm lwm cov organic tebchaw.
Txoj kev:
- Txoj kev npaj ntawm 2,6-difluorobenzonitrile yog tsuas yog tau los ntawm cov tshuaj tiv thaiv ntawm 2,6-difluorobenzyl cawv thiab sodium cyanide nyob rau hauv lub xub ntiag ntawm ib tug alkaline catalyst.
- Cov kauj ruam tshwj xeeb suav nrog cov tshuaj tiv thaiv ntawm 2,6-difluorobenzyl cawv nrog sodium cyanide nyob rau hauv alkaline tej yam kev mob, ua raws li acidification kom tau 2,6-difluorobenzonitrile khoom.
Cov ntaub ntawv kev nyab xeeb:
- 2,6-difluorobenzonitrile muaj toxicity tsawg, tab sis tseem yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab ua pa.
- Cov txheej txheem kev nyab xeeb thiab cov cuab yeej tiv thaiv kom raug yuav tsum tau ua raws li thaum siv lossis khaws cia.
- Thaum qhov sib xyaw ua ke raug chwv lossis nqus tau, nws yuav tsum tau muab ntxuav lossis tso pa tawm tam sim ntawd thiab yuav tsum tau nrhiav kev kho mob sai.
