Mawu Oyamba

2-Chloro-5-fluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

 

Ubwino:

- Mawonekedwe: Opanda utoto mpaka makristalo achikasu owala kapena ufa wonyezimira.

- Kusungunuka: kusungunuka mu zosungunulira za organic, kusungunuka pang'ono m'madzi.

 

Gwiritsani ntchito:

- 2-Chloro-5-fluorobenzoic acid nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic.

- Itha kugwiritsidwanso ntchito ngati organic synthesis reagent komanso chothandizira.

 

Njira:

2-Chloro-5-fluorobenzoic acid nthawi zambiri imakonzedwa ndi:

2-chloro-5-fluorobenzyl mowa amachitidwa ndi sodium hydroxide (NaOH) kapena potaziyamu hydroxide (KOH) kuti apeze mchere wofanana wa sodium kapena mchere wa potaziyamu.

Imapangidwa ndi hydrochloric acid kuti ipange 2-chloro-5-fluorobenzoic acid.

 

Zambiri Zachitetezo:

- 2-Chloro-5-fluorobenzoic acid ndi chinthu choyaka ndipo chiyenera kupewedwa kuti zisakhudzidwe ndi oxidizing amphamvu kapena mpweya.

- Valani zida zodzitetezera zoyenera, monga magolovesi, magalasi, ndi zovala zodzitetezera, pogwira kapena pogwira.

- Pewani kutulutsa fumbi kapena madzi ake ndikugwirira ntchito pamalo abwino mpweya wabwino.

- Sungani kutali ndi kutentha kwakukulu, moto, ndi kuwala kwa dzuwa, ndipo sungani chidebecho chotsekedwa mwamphamvu.
