| 摘 要： | 以硼酸、甘油为原料,在氮气保护下合成硼酸二甘油酯,然后在强酸性阳离子交换树脂催化下分别与月桂酸、肉豆蔻酸、硬脂酸反应合成出3种具有半极性键的有机硼酸酯表面活性剂.用红外光谱确定了产物的结构.研究了硼酸二甘油酯月桂酸酯的合成工艺,得到了优化的工艺条件,结果表明:硼酸与甘油的摩尔比为1∶2.0,反应温度为180 ℃,反应时间为4 h时,硼酸二甘油酯的收率为96.0%;硼酸二甘油酯与月桂酸的摩尔比为1∶0.9,反应温度为200 ℃,反应时间为3.5 h,催化剂用量(相对于月桂酸的质量)为2.0%时,月桂酸转化率为97.5%.硼酸二甘油酯肉豆蔻酸酯和硼酸二甘油酯硬脂酸酯在相同的工艺条件下合成时酸转化率分别为97.0%和96.4%.该工艺具有酸转化率高,后处理工艺简单的优点.
