I-Methyl Phenylglyoxalate Nge-Cas 15206-55-0

I-Benzoic acid ne-methanol itholakala nge-esterification. I-cyclic methanol ne-benzoylformic acid kwengezwe ebhodweni lokusabela, futhi i-sulfuric acid yengezwa kancane kancane ngokushukumisa. Ngemuva kokushisa ngaphansi kwe-reflux amahora angu-12, i-methanol eyengeziwe yatholwa. Umkhiqizo owenziwe i-esterified uye wahlukaniswa ngesisombululo se-sodium carbonate exutshiwe, ungqimba lukawoyela lwahlukaniswa, futhi ungqimba olunamanzi lwakhishwa nge-benzene. I-extract ihlanganiswe nongqimba lwamafutha, yomiswa phezu kwe-anhydrous sodium sulfate, bese i-distilled. Okokuqala, i-benzene ye-solvent yatholwa, kwase kuthi ama-boilers aphansi ahwamuka ngaphansi kwengcindezi encishisiwe. Kwabe sekuqoqwa izingxenyana futhi zathathwa njenge-methyl benzoylformate.
