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, hoʻokaʻawale ʻia ka ʻaila ʻaila, a lawe ʻia ka papa wai me 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.
