| 摘 要： | 以对甲苯磺酸为催化剂,以葡萄糖和脂肪醇作原料,采用转糖苷化法合成了烷基葡糖苷,考察了工艺条件对合成烷基糖苷的影响。结果表明,催化剂∶葡萄糖=0.011∶1(质量比),葡萄糖∶正丁醇=1∶3(摩尔比),正丁醇∶脂肪醇=1∶1(摩尔比),常压反应,反应温度为110~115℃,葡萄糖转化率可达98.9%。

| Abstract: | The alkyl polyglucosides were synthesized from p-toluenesulfonic acid,glucose and dodecyl alcohol by transglycosidation.The influence factors were discussed.The experimental results indicated that m(catalyst)∶m(glucose)=0.011∶1,n(glucose)∶n(butyl alcohol)=1∶3,n(butyl alcohol)∶n(dodecyl alcohol)=1∶1,the reaction temperature must be controlled with in the range of 110~115 ℃,the conversion of the glucose can be reach about 98.9%. |
