Taw qhia
2-Bromo-6-chlorobenzoic acid. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Zoo li: tsis muaj xim crystalline khoom
- Solubility: soluble nyob rau hauv organic solvents xws li cawv thiab ether solvents
- Tshuaj muaj pes tsawg leeg: 2-bromo-6-chlorobenzoic acid yog ib tug muaj zog acid uas yuav neutralized nrog alkalis. Nws kuj tuaj yeem txo qis rau nws cov benzoic acid los yog benzaldehyde.
Siv:
-2-Bromo-6-chlorobenzoic acid tuaj yeem siv rau hauv cov organic synthesis cov tshuaj tiv thaiv, thiab feem ntau yog siv los ua ib qho nruab nrab hauv kev lag luam tshuaj thiab tshuaj tua kab.
Txoj kev:
-2-Bromo-6-chlorobenzoic acid tuaj yeem tau los ntawm p-bromobenzoic acid los ntawm kev hloov cov tshuaj tiv thaiv. Txoj kev npaj ib txwm yog ua kom cov tshuaj p-bromobenzoic acid nrog cov kua qaub diluted, ntxiv stannous chloride (II.) ua cov catalyst, thiab tom qab qhov tsim nyog kub thiab cov tshuaj tiv thaiv lub sijhawm, cov khoom lag luam tau txais.
Cov ntaub ntawv kev nyab xeeb:
-2-Bromo-6-chlorobenzoic acid yog organohalide thiab yuav tsum tau siv ceev faj.
- Kev sib cuag ntawm daim tawv nqaij yuav ua rau khaus thiab liab, yog li tsis txhob sib cuag ntawm daim tawv nqaij kom ntau li ntau tau thiab hnav hnab looj tes tiv thaiv tsim nyog.
- Yog tias nqus tau los yog nqus tau, nws yuav ua rau muaj kev phom sij rau lub ntsws thiab lub plab zom mov, yog li nws yuav tsum tau ceev kom tsis txhob nqus tau thiab tsis txhob noj.
- Thaum lub sijhawm ua haujlwm, qhov cua zoo yuav tsum tau khaws cia thiab ua haujlwm hauv qhov chaw kaw yuav tsum zam.
