Taw qhia
M-fluorobenzonitrile, tseem hu ua 2-fluorobenzonitrile, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm m-fluorobenzonitrile:
Zoo:
- Cov tsos mob: M-fluorobenzonitrile yog cov kua tsis muaj xim lossis crystalline khoom.
- Solubility: Nws yog soluble hauv ntau cov kuab tshuaj organic xws li ethanol, chloroform, thiab lwm yam.
- Toxicity: M-fluorobenzonitrile muaj qee yam toxicity rau tib neeg lub cev thiab yuav tsum tau saib xyuas thiab siv nrog kev saib xyuas.
Siv:
- Intermediates: M-fluorobenzonitrile yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab tuaj yeem siv los ua ke lwm cov organic sib txuas.
- Tshuaj tua kab: Nws kuj tseem siv tau los ua raw khoom siv tshuaj tua kab.
Txoj kev:
M-fluorobenzonitrile tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm fluorochlorobenzene thiab sodium cyanide nyob rau hauv alkaline tej yam kev mob.
Cov ntaub ntawv kev nyab xeeb:
- tawv nqaij thiab qhov muag khaus: M-fluorobenzonitrile tuaj yeem ua rau tawv nqaij thiab qhov muag khaus, thiab kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav tsum zam thaum siv nws.
- Kev pheej hmoo ntawm kev nqus pa: Kev nqus pa ntawm m-fluorobenzonitrile vapor tuaj yeem ua rau ua pa ua pa, yog li xyuas kom meej tias nws siv rau hauv qhov chaw muaj cua zoo.
- Cia thiab tuav: M-fluorobenzonitrile yuav tsum muab cia rau hauv lub thawv airtight, kom deb ntawm hluav taws kub thiab kub, thiab tsis txhob sib cuag nrog oxidants thiab acids. Cov cuab yeej tiv thaiv tus kheej xws li tsom iav, hnab looj tes, thiab lwm yam yuav tsum hnav thaum tuav.
