Methyl Phenylglyoxalate NgeCas 15206-55-0

I-benzoic acid kunye ne-methanol zifumaneka nge-esterification. I-cyclic methanol kunye ne-benzoylformic acid zongezwa kwi-reaction pot, kwaye i-asidi ye-sulfuric yongezwa ngokucothayo ngokuvuselela. Emva kokufudumeza ngaphantsi kwe-reflux ye-12 h, i-methanol engaphezulu yafunyanwa. Imveliso ye-esterified yayingathathi hlangothi kunye nesisombululo se-sodium carbonate edibeneyo, i-oyile ye-oyile yahlulwa, kwaye i-aqueous layer ikhutshwe nge-benzene. Isicatshulwa sidityaniswe ne-oyile yomaleko, yomiswa phezu kwe-anhydrous sodium sulfate, kwaye emva koko i-distilled. Okokuqala, i-solvent benzene yafunyanwa, kwaye emva koko iibhoyila eziphantsi zakhutshwa ngumphunga phantsi koxinzelelo olucuthiweyo. Emva koko amaqhezu aqokelelwa kwaye athathwa njenge-methyl benzoylformate.
