Methyl Phenylglyoxalate Me te Cas 15206-55-0

Ka whiwhihia te waikawa benzoic me te methanol mā te esterification. I tāpirihia te methanol cyclic me te waikawa benzoylformic ki te kohua tauhohenga, ā, i tāpirihia mārire te waikawa whanariki me te whakaoho. I muri i te whakamahana i raro i te reflux mō te 12 hāora, ka whakahokia mai te methanol taikaha. I whakakorengia te hua esterified ki te otinga konutai kāponāte waimeha, i wehea te paparanga hinu, ā, i tangohia te paparanga wai ki te benzene. I whakakotahihia te tangohanga ki te paparanga hinu, i whakamaroketia ki runga i te konutai whanariki kore wai, kātahi ka whakawetohia. Tuatahi, ka whakahokia mai te benzene whakarewa, kātahi ka mimitihia ngā poihau iti i raro i te pēhanga iti. Kātahi ka kohia ngā wāhanga ka tangohia hei methyl benzoylformate.
