Chii chinonzi Methyl Phenylglyoxalate neCas 15206-55-0?

Benzoic acid nemethanol zvinowanikwa ne esterification. Cyclic methanol ne benzoylformic acid zvakaiswa mu reaction pot, uye sulfuric acid yakawedzerwa zvishoma nezvishoma nekukurunga. Mushure mekudziya pasi pe reflux kwemaawa gumi nemaviri, methanol yakawandisa yakatorwa. Chinhu chakagadziriswa chakabviswa ne diluted sodium carbonate solution, oil layer yakaparadzaniswa, uye aqueous layer yakabviswa ne benzene. Extract yakasanganiswa ne oil layer, yakaomeswa pamusoro pe anhydrous sodium sulfate, yozobva yadistillwa. Kutanga, solvent benzene yakatorwa, uye boilers dzakaderera dzakabviswa ne pressure yakaderera. Zvadaro zvikamu zvakaunganidzwa ndokutorwa se methyl benzoylformate.
