ʻO Methyl Phenylglyoxalate Me Cas 15206-55-0
Loaʻa ka waikawa Benzoic a me ka methanol ma o ka esterification. Ua hoʻohui ʻia ka methanol cyclic a me ka waikawa benzoylformic i loko o ka ipu hana, 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 h, ua hoʻihoʻi ʻia ka methanol keu. Ua hoʻopau ʻia ka huahana esterified me ka hopena sodium carbonate dilute, ua hoʻokaʻawale ʻia ka papa aila, a ua unuhi ʻia ka papa wai me ka benzene. Ua hui pū ʻia ka extract me ka papa aila, ua hoʻomaloʻo ʻia ma luna o ka sodium sulfate anhydrous, a laila ua hoʻoheheʻe ʻia. ʻO ka mua, ua hoʻihoʻi ʻia ka benzene solvent, a laila ua hoʻoheheʻe ʻia nā paila haʻahaʻa ma lalo o ke kaomi i hoʻemi ʻia. A laila ua hōʻiliʻili ʻia nā ʻāpana a lawe ʻia e like me ka methyl benzoylformate.
