Methyl Phenylglyoxalate Me Cas 15206-55-0
Ko te waikawa benzoic me te methanol ka riro ma te esterification.I tapirihia te mewaro pataka me te waikawa benzoylformic ki te kohua hohenga, ka ata taapirihia te waikawa pungatara me te whakaoho.Whai muri i te whakamahana i raro i te reflux mo te 12 haora, ka hoki mai te methanol i te taikaha.I whakakorehia te hua esterified ki te wairewa konutai warowaikawa waimeha, ka wehea te paparanga hinu, ka tangohia te paparanga wai ki te benzene.I honoa te tangohanga ki te paparanga hinu, ka whakamaroke ki runga i te konutai konutai pūkawa, katahi ka whakamaroke.Tuatahi, i whakahokia mai te benzene whakarewa, katahi ka whakaeto nga kohua iti i raro i te pehanga iti.Katahi ka kohia nga hautau ka tangohia hei methyl benzoylformate.
