Taw qhia

2-Chlorofluorobenzene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-chlorofluorobenzene:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: Soluble nyob rau hauv feem ntau cov organic solvents, insoluble nyob rau hauv dej

 

Siv:

2-Chlorofluorobenzene muaj ntau yam kev siv hauv kev lag luam:

- Siv los ua cov kuab tshuaj: Nws muaj cov solubility zoo thiab tuaj yeem siv los ua cov kuab tshuaj rau cov organic synthesis.

- Siv nyob rau hauv tshuaj tua kab synthesis: raws li ib tug intermediate nyob rau hauv cov txheej txheem ntawm cov tshuaj tua kab.

- Rau coatings thiab adhesives: tuaj yeem siv los ua cov kuab tshuaj kom ua tau zoo ntawm cov txheej thiab cov nplaum.

- Lwm yam kev siv: Nws kuj tuaj yeem siv rau hauv kev sib txuas ntawm qee cov tshuaj reagents lossis ua cov khoom pib hauv cov txheej txheem organic synthesis.

 

Txoj kev:

2-Chlorofluorobenzene tuaj yeem npaj tau los ntawm fluoroalkylation, ib txoj hauv kev ua haujlwm fluorobenzene nrog cuprous chloride (CuCl) hauv cov kuab tshuaj tsis zoo xws li tetrahydrofuran.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Chlorofluorobenzene ua rau khaus thiab tuaj yeem tsim teeb meem rau lub qhov muag thiab tawv nqaij, yog li nws yuav tsum tau zam thaum sib cuag.

- Thaum lub sijhawm ua haujlwm, yuav tsum tau ntsuas kev nyab xeeb tsim nyog, xws li hnav tsom iav tiv thaiv, hnab looj tes thiab khaub ncaws tiv thaiv tsim nyog.

- Thaum khaws cia thiab siv, cia kom deb ntawm qhov hluav taws kub thiab qhov kub thiab txias, thiab xyuas kom muaj cua zoo.

- Yog tias nqos los yog nqus tau, nrhiav kev kho mob tam sim ntawd. Yog ua tau, muab cov ntsiab lus ntawm cov tshuaj rau tus kws kho mob mus ntsib.
