    • PROBLEM TO BE SOLVED: To provide a method for purifying an ester, by which the highly pure ester free of anionic impurities can efficiently be obtained. SOLUTION: Provided is a method for purifying the ester, characterized by treating the ester containing anionic impurities with a basic anion exchange resin not having an OH type strongly basic exchange group, to remove the anionic impurities. A basic anion exchange resin having inactivated OH type strongly basic exchange groups may be used. The inactivation is preferably performed by bringing the ester into contact with a basic anion exchange resin having OH type strongly basic exchange groups to inactivate the OH type strongly basic exchange groups, or by bringing the ester into contact with a neutral salt to inactivate the OH type strongly basic exchange groups.

    • 要解决的问题:提供一种纯化酯的方法,通过该方法可以有效地获得不含阴离子杂质的高纯度酯。 解决方案:提供一种纯化酯的方法,其特征在于用不具有OH型强碱性交换基团的碱性阴离子交换树脂处理含有阴离子杂质的酯,以除去阴离子杂质。 可以使用具有失活的OH型强碱性交换基团的碱性阴离子交换树脂。 优选通过使酯与具有OH型强碱性交换基团的碱性阴离子交换树脂接触来灭活OH型强碱性交换基团,或通过使酯与中性盐接触以使OH型失活来进行失活 强大的基本交流团体 版权所有(C)2009,JPO&INPIT
