Taw qhia

O-fluorobenzoyl chloride, nrog rau cov tshuaj formula C7H4ClFO, 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 o-fluorobenzoyl chloride:

 

1. Xwm:

- Cov tsos mob: O-fluorobenzoyl chloride yog xim tsis muaj xim rau lub teeb daj.

- Fragrance: muaj ib tug tshwj xeeb pungent tsw.

- Ceev: 1.328 g / mL ntawm 25 ° C (lit.)

- Melting thiab boiling ntsiab lus: 4 ° C (lit.) thiab 90-92 ° C / 15 mmHg (lit.)

- Solubility: Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li ethanol, ether, acetone, thiab lwm yam.

 

2. Kev siv:

- O-fluorobenzoyl chloride yog ib qho tshuaj reagent feem ntau siv rau hauv cov organic synthesis rau kev sib txuas ntawm ketones thiab cawv.

- Nws tuaj yeem siv ua cov tshuaj tua kab mob thiab tshuaj tua kab mob.

 

3. Txoj kev:

Txoj kev npaj ntawm o-fluorobenzoyl chloride feem ntau yog cov tshuaj tiv thaiv ntawm o-fluorobenzoic acid nrog thionyl chloride:

C6H4FO2OH + SOCl2 → C6H4FOCl + SO2 + HCl

 

4. Cov ntaub ntawv kev nyab xeeb:

- O-fluorobenzoyl chloride yog cov tshuaj tsw qab tsw ntxhiab thiab yuav tsum zam los ntawm kev nqus nws cov pa.

- Hnav hnab looj tes, tsom iav, thiab hnav khaub ncaws thaum siv lossis tuav o-fluorobenzoyl chloride.

- Tsis txhob kov ntawm daim tawv nqaij thiab nqos. Yog tias muaj kev sib cuag tsis raug, yaug tam sim nrog dej kom ntau thiab nrhiav kev kho mob yog tias tsim nyog.

- Khaws lub thawv kaw kom nruj kom deb ntawm qhov hluav taws kub thiab qhov chaw kub thaum khaws cia kom tsis txhob muaj hluav taws xob thiab tawg.

 

Ua raws li kev soj ntsuam kom raug thiab ntsuas kev nyab xeeb thaum tuav lossis siv cov khoom sib txuas thiab xa mus rau cov ntaub ntawv kev nyab xeeb ntawm cov khoom lossis tshuaj.
