Taw qhia
Fluorobenzoyl chloride 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 p-fluorobenzoyl chloride:
Zoo:
- Cov tsos mob: tsis muaj xim rau cov kua daj daj.
- Solubility: Soluble nyob rau hauv cov organic solvents xws li ether, chloroform thiab toluene.
Siv:
- Fluorobenzoyl chloride tuaj yeem siv los ua ib qho tseem ceeb reagent nyob rau hauv cov synthesis ntawm cov organic tebchaw, thiab feem ntau yog siv nyob rau hauv fluorination cov tshuaj tiv thaiv ntawm esters thiab ethers.
Txoj kev:
Txoj kev npaj ntawm fluorobenzoyl chloride yog tsuas yog tau los ntawm reacting fluorobenzoic acid nrog phosphorus pentachloride (PCl5). Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:
C6H5COOH + PCl5 → C6H5COCl + POCl3 + HCl
Cov ntaub ntawv kev nyab xeeb:
- Fluorobenzoyl chloride yog qhov txaus ntshai zoo, khaus khaus thiab corrosive. Cov khoom siv tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv yuav tsum hnav thaum siv.
- Tsis txhob sib chwv nrog daim tawv nqaij, nqus pa ntawm cov pa los yog cov kua dej txau.
- Flubenzoyl chloride yuav tsum muab khaws cia rau hauv qhov chaw kaw, qhuav, qhov chaw txias, kom deb ntawm cov hluav taws kub thiab cov khoom siv hluav taws xob.
