Taw qhia
O-chlorobenzoyl chloride hmoov. Nov yog qee cov khoom tseem ceeb thiab cov ntaub ntawv hais txog qhov sib xyaw no:
Cov Khoom Siv: O-chlorobenzoyl chloride yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog corrosive heev thiab reacts nrog dej los tsim hydrogen chloride gas. Nws muaj volatility siab thiab yog yooj yim soluble nyob rau hauv organic solvents xws li ethanol, ether thiab benzene.
Siv: O-chlorobenzoyl chloride yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Piv txwv li, nws tuaj yeem siv los ua cov tshuaj tua kab zoo li cov tshuaj tua kab xws li o-chlorophenol thiab o-chlorophonool, nrog rau kev sib xyaw ntawm dyes thiab phosphates.
Txoj kev npaj: Txoj kev npaj ntawm o-chlorobenzoyl chloride feem ntau yog ua los ntawm reacting benzoyl chloride nrog txhuas chloride ntawm chav tsev kub. Cov kauj ruam tshwj xeeb yog tshem tawm benzoyl chloride hauv anhydrous ether, tom qab ntawd maj mam ntxiv aluminium chloride thiab do tag nrho, thiab tom qab cov tshuaj tiv thaiv tiav, cov khoom lag luam yog tau los ntawm distillation thiab purification.
Cov ntaub ntawv kev nyab xeeb: O-chlorobenzoyl chloride yog ib qho ua rau khaus thiab corrosive compound thiab yuav tsum tau saib xyuas. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes tiv thaiv tshuaj, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv. Tsis txhob kov cov tawv nqaij thiab qhov muag, thiab tsis txhob nqus nws cov vapors. Ib puag ncig zoo-ventilated yuav tsum tau khaws cia thaum siv lossis khaws cia.
