3-Fluorobenzoyl chloride (CAS # 1711-07-5) Kev taw qhia
M-fluorobenzoyl chloride (tseem hu ua 2-fluorobenzoyl chloride) yog cov organic compound. Hauv qab no yog cov lus qhia ntxaws ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no.
Zoo:
M-fluorobenzoyl chloride yog cov kua uas tsis muaj xim rau daj ntseg daj uas muaj ntxhiab tsw thiab tsw ntxhiab ntawm chav tsev kub. Nws yog insoluble hauv dej, tab sis nws tuaj yeem ua rau miscible nrog qee cov kuab tshuaj organic xws li ethers, ketones, cawv, thiab lwm yam.
Kev Siv: Nws tuaj yeem siv rau hauv kev npaj cov tshuaj tsw qab ketones (piv txwv li, formyl chloride) thiab amides (xws li, formylchloramine). Nws kuj tseem siv tau los ua ib qho tseem ceeb nruab nrab ntawm cov tshuaj tua kab thiab dyes.
Txoj kev:
Txoj kev npaj ntawm m-fluorobenzoyl chloride feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm m-fluorobenzoic acid nrog anhydrous thionyl chloride. Cov txheej txheem tshuaj tiv thaiv yuav tsum tau ua nyob rau hauv ib qho chaw inert thiab tsis kub. Thaum kawg ntawm cov tshuaj tiv thaiv, cov khoom kawg tuaj yeem tau txais los ntawm kev kho mob nrog dej thiab tshuaj acidic.
Cov ntaub ntawv kev nyab xeeb:
M-fluorobenzoyl chloride yog ib qho ua rau khaus khaus uas tuaj yeem ua rau khaus thiab kub hnyiab thaum sib cuag nrog daim tawv nqaij thiab qhov muag. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm. Lub compound yuav tsum tau muab khaws cia kom zoo, tsis txhob sib cuag nrog cov khoom xws li oxidants thiab muaj zog alkalis, thiab tsis txhob ignition thiab kub.
