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 we-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.
