3- trifluoromethyl benzoic acid yog hom tshuaj nruab nrab hauv tshuaj thiab tshuaj tua kab, uas muaj cov ntaub ntawv thov dav heev hauv tshuaj thiab tshuaj tua kab thiab lwm cov teb. Tam sim no, muaj feem ntau yog cov hauv kev npaj ua hauv qab no: 1) m-difluorotoluene raws li cov khoom siv raw, nrog 30% fuming sulfuric acid cua sov tsis kam kho hydrolysis, txias rau hauv dej khov, cov khoom lim, cov paib: 66.1%. Qhov txheej txheem npaj no muaj cov qoob loo tsis tshua muaj txiaj ntsig thiab ua kom muaj ntau ntau ntawm cov khib nyiab acid, uas ua tsis tau raws li qhov yuav tsum tau ua ntawm ntsuab Chemicalbook ntau lawm. 2) Kev noj tshuaj m-trifluoromethyl benzyl chloride ua cov khoom siv raw, chlor nrog chlorine roj hauv qab qhov kev ua ntawm 50-90 ℃, thiab tom qab ntawd reflux hydrolyzed nrog 2.5-10% sodium hydroxide rau neutralize thiab lim cov khoom m-trifluoromethyl benzoic acid, nrog tag nrho cov txiaj ntsig ntawm 76.5-85.5% hauv ob kauj ruam. Kev siv cov kua roj chlorine nyob rau hauv qhov kev npaj no yuav ua rau muaj kev txwv tsawg heev rau kev siv, thiab nws yog ob qhov tshuaj tiv thaiv, tus nqi tag nrho yuav tsis siab heev.
