摘　　要：采用直接苷化法合成了十二烷基葡糖苷。通过正交试验,考察了原料配比、催化剂用量和反应温度等因素对产率的影响。得到了最佳反应条件:十二醇与葡萄糖的摩尔比为3.0∶1,催化剂与葡萄糖的质量比为0.01∶1,反应温度为120℃。结果表明:影响产率的主要因素为催化剂和葡萄糖的配料比。The alkyl polyglucoside was synthesized by the direct reaction of glucose and laurel alcohol. The influence factors are discussed and the optimum conditions are as follows： mole ratio of dodecyl alcohol to glucose 3.0 ： 1, quality ratio of catalyst to glucose is 0.01 ： 1 and reaction temperature 120℃. Experiment shows that the major factor effecting on the reaction yield is the ratio of catalyst to glucose.
