Methyl Phenylglyoxalate Me Cas 15206-55-0

Loaʻa ka waikawa benzoic a me ka methanol ma o ka esterification.Hoʻohui ʻia ka methanol cyclic a me ka waikawa benzoylformic i ka ipu hao, a ua hoʻohui mālie ʻia ka waikawa sulfuric me ka hoʻoulu ʻana.Ma hope o ka hoʻomehana ʻana ma lalo o ka reflux no 12 mau hola, ua loaʻa hou ka methanol keu.Ua hoʻokaʻawale ʻia ka huahana esterified me ka dilute sodium carbonate solution, ua hoʻokaʻawale ʻia ka ʻaila ʻaila, a ua unuhi ʻia ka papa wai me ka benzene.Hoʻohui ʻia ka extract me ka ʻaila ʻaila, hoʻomaloʻo ʻia ma luna o ka sodium sulfate anhydrous, a laila distilled.ʻO ka mua, ua hoʻihoʻi ʻia ka benzene solvent, a laila hoʻopau ʻia nā paila haʻahaʻa ma lalo o ke kaomi hoʻemi.A laila, ʻohi ʻia nā hakina a lawe ʻia ma ke ʻano he methyl benzoylformate.
