Taw qhia
4-Chloro-2-bromobenzoic acid kuj hu ua 4-chloro-2-bromobenzoic 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:
4-Chloro-2-bromo-benzoic acid yog dawb crystalline khoom. Nws muaj cov solubility tsawg thiab yuav luag insoluble hauv dej, tab sis nws yog soluble hauv cov kuab tshuaj organic.
Siv:
Cov tshuaj no feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis cov tshuaj tiv thaiv. 4-Chloro-2-bromo-benzoic acid kuj tseem siv tau los ua cov tshuaj zas dispersant hauv kev lag luam dye.
Txoj kev:
Ib txoj hauv kev siv feem ntau rau kev npaj ntawm 4-chloro-2-bromo-benzoic acid yog ua kom 2-bromo-4-nitrobenzoic acid nrog nitrous acid kom tau 2-bromo-4-nitrophenol, thiab tom qab ntawd cov khoom lag luam tau txais los ntawm tshuaj tiv thaiv thiab kev kho mob.
Cov ntaub ntawv kev nyab xeeb:
4-Chloro-2-bromo-benzoic acid feem ntau suav hais tias muaj toxicity tsawg nyob rau hauv ib txwm siv thiab cia tej yam kev mob. Tej zaum nws yuav muaj kev cuam tshuam rau qhov muag, tawv nqaij, thiab ua pa. Kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag yuav tsum zam thaum siv, thiab kev ua pa zoo yuav tsum tau tswj xyuas. Thaum tuav los yog muab tshem tawm, yuav tsum muaj kev tiv thaiv tus kheej tsim nyog xws li kev tiv thaiv qhov muag thiab tes. Yog tias cov tshuaj nqus tau los yog nqus tau, nrhiav kev kho mob tam sim ntawd.
