Siv thiab Kev Npaj
Siv:
2, {{4- dibromobobenzoic acid yog cov organic synthiater thiab plays lub synthesis colounds xws li cov tshuaj orgomicts xws li cov tshuaj orgomicts xws li cov kws tshuaj, thiab tshuaj tua kab.
Txoj kev npaj:
Qhov kev npaj ntawm 2, {4- dibromobobenzoic acid feem ntau yog los ntawm kev tawm tsam bromination ntawm benzoic acid. Nyob rau hauv cov kauj ruam tshwj xeeb, benzoic acid thawj tus reacts nrog bromine nyob rau hauv lub xub ntiag ntawm ib acid catalyst los tsim bromobenzoic acid. Tom qab ntawd, nws tau los ntawm hydrolyzing lub bromobenzoic acid.
