Taw qhia

2-Chloro-5-fluorobenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: tsis muaj xim rau lub teeb daj daj lossis crystalline hmoov.

- Solubility: soluble hauv cov kuab tshuaj organic, me ntsis soluble hauv dej.

 

Siv:

- 2-Chloro-5-fluorobenzoic acid feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.

- Nws kuj tseem siv tau los ua cov organic synthesis reagent thiab catalyst.

 

Txoj kev:

2-Chloro-5-fluorobenzoic acid feem ntau yog npaj los ntawm:

2-chloro-5-fluorobenzyl cawv yog reacted nrog sodium hydroxide (NaOH) los yog potassium hydroxide (KOH) kom tau txais cov sodium ntsev los yog poov tshuaj ntsev.

Nws yog acidified los ntawm hydrochloric acid los tsim 2-chloro-5-fluorobenzoic acid.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Chloro-5-fluorobenzoic acid yog cov khoom siv hluav taws xob thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov oxidizing muaj zog lossis cov pa oxygen.

- Hnav cov khoom tiv thaiv tsim nyog, xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv, thaum tuav lossis tuav.

- Tsis txhob nqus nws cov plua plav lossis cov tshuaj tov thiab ua haujlwm hauv qhov chaw muaj cua zoo.

- Khaws kom deb ntawm qhov kub thiab txias, hluav taws kub, thiab tshav ntuj ncaj qha, thiab khaws lub ntim kom nruj.
