摘要： A process for the production of liquid epoxy resins, including: contacting a polyhydric phenol and an epihalohydrin in the presence of an ionic catalyst to form a halohydrin intermediate reaction product; concurrently: reacting a portion of the halohydrin intermediate reaction product with an alkali hydroxide to form a solid salt suspended in a liquid mixture including a dehydrohalogenated product and unreacted halohydrin intermediate, wherein the alkali hydroxide is used at less than a stoichiometric amount; and removing water and epihalohydrin as a vapor from the reacting mixture; separating the solid salt from the liquid mixture; reacting at least a portion of the unreacted halohydrin intermediate with an alkali hydroxide in the presence of water to form an organic mixture including an epoxy resin and unreacted epihalohydrin and an aqueous solution including a salt; separating the aqueous mixture from the organic mixture; and separating the unreacted epihalohydrin from the liquid epoxy resin.

摘要翻译： 一种制备液体环氧树脂的方法，包括：在离子催化剂存在下使多元酚与表卤醇接触以形成卤代醇中间体反应产物; 同时：将一部分卤代醇中间体反应产物与碱金属氢氧化物反应以形成悬浮在包含脱卤化氢产物和未反应的卤代醇中间体的液体混合物中的固体盐，其中碱金属氢氧化物以小于化学计量的量使用; 并从反应混合物中除去作为蒸汽的水和表卤代醇; 从液体混合物中分离出固体盐; 在水的存在下使至少一部分未反应的卤代醇中间体与碱金属氢氧化物反应，形成包含环氧树脂和未反应的表卤代醇的有机混合物和包含盐的水溶液; 从有机混合物中分离含水混合物; 并从液态环氧树脂中分离出未反应的表卤代醇。
