    • The present invention is directed to a process for the preparation of the saponification products of lactones, preferably three- to eight-membered lactones. The present invention is also directed to a process for the preparation of compounds having general formula (I): wherein M is selected from the group consisting of cationic species, preferably metal cations (even more preferably Na), from a compound having the formula (II): comprising reacting a compound having formula (II) with a suitable hydroxide salt (M-OH) (III) such as, preferably, sodium hydroxide, in an aqueous medium. The reaction preferably utilizes a continuous process method for the substantial consumption of reagent and continuous, semi-continuous, and/or batch-wise processing for final consumption of reagent.
    • 本发明涉及制备内酯,优选三至八元内酯的皂化产物的方法。 本发明还涉及制备具有通式(I)的化合物的方法:其中M选自具有式(I)的化合物的阳离子种类,优选金属阳离子(甚至更优选Na) II):包括在水性介质中使具有式(II)的化合物与合适的氢氧化物盐(M-OH)(III),例如优选氢氧化钠反应。 该反应优选利用连续的方法来大量消耗试剂和连续,半连续和/或分批处理以最终消耗试剂。
