Taw qhia
Furancaryl chloride hmoov.
Zoo:
Furancaryl chloride yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw. Nws yog yooj yim soluble nyob rau hauv cov organic solvents xws li ethanol, ether thiab benzene. Nws reacts nrog dej los tsim furanoic acid thiab tso tawm hydrogen chloride gas.
Siv:
Furancaryl chloride feem ntau yog siv los ua ib qho tseem ceeb reagent hauv organic synthesis. Nws tuaj yeem siv los ua acylation reagent rau acylation cov tshuaj tiv thaiv los qhia furancarbyl pawg rau hauv lwm cov tebchaw.
Txoj kev:
Furazyl chloride tuaj yeem tau txais los ntawm kev ua haujlwm furanoic acid nrog thionyl chloride. Furancarboxylic acid reacts nrog thionyl chloride hauv ib qho hnyav hnyav xws li methylene chloride kom tau txais furoformyl sulfoxide. Tsis tas li ntawd, nyob rau hauv lub xub ntiag ntawm thionyl chloride, ib qho acidic catalyst (xws li, phosphorus pentoxide) yog siv los ua kom sov cov tshuaj tiv thaiv los tsim furanyl chloride.
Cov ntaub ntawv kev nyab xeeb:
Furanyl chloride yog ib qho teeb meem tshuaj uas ua rau khaus thiab corrosive. Thaum ntsib daim tawv nqaij thiab qhov muag, yaug tam sim ntawd nrog dej kom ntau. Kev nqus pa ntawm nws cov vapors yuav tsum zam thaum lub sijhawm ua haujlwm thiab cov cuab yeej tiv thaiv tsim nyog xws li lub tshuab ua pa, hnab looj tes thiab tsom iav yuav tsum siv yog tias tsim nyog. Khaws rau hauv lub thawv airtight, kom deb ntawm oxidants thiab kub. Thaum tuav furanyl chloride, yuav tsum tau saib xyuas cov txheej txheem kev nyab xeeb.
