Iyini iMethyl Phenylglyoxalate eneCas 15206-55-0?

I-Benzoic acid kanye ne-methanol kutholakala ngokwenziwa kwe-esterification. I-cyclic methanol kanye ne-benzoylformic acid kwanezelwa ebhodweni lokusabela, kwathi i-sulfuric acid yanezelwa kancane kancane ngokuxuba. Ngemva kokufudumala ngaphansi kwe-reflux amahora ayi-12, i-methanol eyengeziwe yatholakala. Umkhiqizo oqinisiwe wasuswa ngesisombululo se-sodium carbonate esincibilikisiwe, ungqimba lwamafutha lwahlukaniswa, kwathi ungqimba lwamanzi lwakhishwa nge-benzene. Ukukhishwa kwahlanganiswa nongqimba lwamafutha, komiswa phezu kwe-sodium sulfate engamanzi, kwabe sekususwa. Okokuqala, kwatholakala i-benzene enyibilikisayo, kwabe sekuthathwa ama-boiler aphansi ngaphansi kwengcindezi encishisiwe. Kwabe sekuqoqwa izingxenyana futhi kwathathwa njenge-methyl benzoylformate.
