乙基葡萄糖苷的催化合成与分离

Catalytic Synthesis and Separation of Ethyl-glucoside

在搅拌釜式间歇反应器中研究了在磺酸型阳离子交换树脂催化下葡萄糖和乙醇的非均相催化反应,实验考察了催化剂种类、粒度、搅拌转速、用量和反应温度对转化率的影响,初步确定了催化反应条件:温度78℃,搅拌转速300 r/min,树脂粒度50～80目,树脂:葡萄糖为1:1,反应20 h转化率可达89%,另外,建立了利用吸附树脂分离乙基葡萄糖苷的新方法,

Research was undertaken to produce ethyl-glucoside by catalysis of ion exchange resin in heterogeneous systems and to determine effects of catalyst type, size, stirring speed and temperature on conversion. 89% of conversion was obtained under the conditions: temperature 78oC, ratio of resin to glucose 1:1, reaction time 20 h. The effective separation of glucoside from glucose was achieved by column chromatography.
