2-Fluorobenzonitrile(CAS #394-47-8 : kuv) Taw qhia
2-Fluorobenzonitrileyog ib qho organic compound. Nws yog xim tsis muaj xim rau daj ntseg daj kua nrog ib tug muaj zog aroma. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-fluorobenzonitrile:
Khoom:
- 2-Fluorobenzonitrile yog cov kua uas tsis tuaj yeem nyob hauv dej thiab muaj lub vapor siab ntawm chav tsev kub.
- Nws muaj solubility zoo thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic xws li ethanol, acetone thiab dimethylformamide.
- Nws ruaj khov hauv huab cua, tab sis cov tshuaj lom neeg muaj kev phom sij tuaj yeem tshwm sim thaum rhuab mus rau qhov kub thiab txias los yog sib cuag nrog cov oxidants muaj zog.
Kev siv:
- Nws tseem tuaj yeem siv los ua cov khoom siv raw rau txheej, dyes thiab fragrances.
Txoj kev npaj:
- Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm 2-fluorobenzonitrile: cyanide hloov txoj kev thiab fluoride hloov txoj kev.
- Txoj kev hloov cyanide yog hais txog kev hloov ntawm pawg cyano mus rau lub nplhaib benzene thiab tom qab ntawd kev taw qhia ntawm fluorine atoms los hloov pawg cyano.
- Fluoride hloov txoj kev hais txog kev siv cov tshuaj fluoride ua raw khoom, reacting nrog chlorine, bromine los yog haloform ntawm lub nplhaib benzene, hloov chlorine, bromine los yog haloform nrog fluorine kom tau 2-fluorobenzonitrile.
Cov ntaub ntawv kev nyab xeeb:
- 2-Fluorobenzonitrile yog tshuaj lom rau tib neeg lub cev. Thov tsis txhob kov ncaj qha rau ntawm daim tawv nqaij, qhov muag thiab nqus pa ntawm nws cov pa.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb thiab khaub ncaws tiv thaiv thaum ua haujlwm.
- Thaum khaws cia, 2-fluorobenzonitrile yuav tsum muab tso rau hauv lub thawv kaw, kom deb ntawm hluav taws thiab oxidants, thiab khaws cia kom zoo kom tsis txhob xau thiab cuam tshuam.
