Yintoni iMethyl Phenylglyoxalate eneCas 15206-55-0?

I-Benzoic acid kunye ne-methanol zifunyanwa ngokuyi-esterification. I-cyclic methanol kunye ne-benzoylformic acid zongezwa kwi-reaction pot, kwaye i-sulfuric acid yongezwa kancinci ngokuyixuba. Emva kokufudumeza phantsi kwe-reflux iiyure ezili-12, i-methanol engaphezulu yafunyanwa. Imveliso e-esterified yasuswa ngesisombululo se-sodium carbonate esinyibilikisiweyo, umaleko weoyile wahlulwa, kwaye umaleko wamanzi wakhutshwa nge-benzene. I-extract yadityaniswa nomaleko weoyile, yomiswa phezu kwe-sodium sulfate engamanzi, yaze yahluzwa. Okokuqala, i-solvent benzene yafunyanwa, kwaye emva koko ii-boilers ezisezantsi zatshiswa phantsi koxinzelelo oluncitshisiweyo. Emva koko ii-fractions zaqokelelwa zaza zathathwa njenge-methyl benzoylformate.
