2,3-丁二醇二缩水甘油醚及其制备方法
摘要：
本发明提供了2,3-丁二醇二缩水甘油醚及其制备方法。其制备的方法包括，2,3-丁二醇与环氧氯丙烷开环反应生成中间产物氯醇醚，氯醇醚与碱反应合成2,3-丁二醇二缩水甘油醚粗产品，粗品经过纯化的步骤获得2,3-丁二醇二缩水甘油醚纯品。本发明获得产品环氧值为9.28%~9.92%，室温25℃的黏度为28~35mPa·S，与环氧树脂E-44混合固化后混合物吸水率相比环氧树脂原料降低16~22%。
摘要（英）：

The invention provides a 2,3-butylene glycol diglycidyl ether and a preparation method thereof. The preparation method comprises the following steps: carrying out a ring opening reaction on 2,3-butylene glycol and chloropropylene oxide to generate an intermediate chlorhydrin ether, reacting the chlorhydrin ether with an alkali to synthesize crude 2,3-butylene glycol diglycidyl ether, and purifying the crude 2,3-butylene glycol diglycidyl ether to otbain pure 2,3-butylene glycol diglycidyl ether. The epoxy value of the 2,3-butylene glycol diglycidyl ether is 9.28-9.92%, the viscosity of the 2,3-butylene glycol diglycidyl ether at room temperature of 25 DEG C is 28-35 mPa.S, and the water absorption rate of a mixture obtained after mixing and solidifying the 2,3-butylene glycol diglycidyl ethe and epoxy resin E-44 is 16-22% lower than that of the epoxy resin raw material.
