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 konutai warowaiha, 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.
