烷基糖苷的合成方法改进与应用研究

A Study of the Improvement in the Method for Synthesizing Alkye Polyglucosides and Its Application

以月桂醇与葡萄糖为原料 ,采用复合催化剂利用直接苷化法合成了十二烷基葡萄糖苷 ,优化了工艺参数 ,得出合适的反应条件 :反应压力为 4.0 5 k Pa;反应温度为 12 0℃ ;醇糖比为 5∶ 1,而剂糖比为 0 .0 0 8.并对其作用机理和所合成糖苷的应用性能作了进一步探讨 .

In this article, we synthesise dodecyl-polyglucosides by using a complex catalyst and through the direct reaction of glucose and laurel alcohol and optimize the technological datum. The proper reaction conditions: reaction pressure 4 05kPa, reaction temperature 120℃, mole ratio of laurel alcohol and glucose 5∶1, mass ratio of complex catalyst and glueos 0 008∶1, are obtained. There is further discussion on the active mechanism and application properties of the APG.
