正丁基葡萄糖苷的合成

Study on the n Butyl Glucoside Synthesis

用直接法合成了正丁基葡萄糖苷，探讨了其各主要影响因素，得出适宜的反应条件为：反应温度１１０ °Ｃ，催化剂∶葡萄糖∶正丁醇＝ ０．０２∶１∶６（摩尔比），反应时间３ｈ，所得产品质量优良，收率＞ ８８％ 。

Alkyl polyglucoside (APG) product is a new type of non ionic surfactant which possesses high foaming power, emulsifying, softening, detergent, and low irritating properties, etc. n Butyl glucoside has been synthesized by the direct reaction between glucose and n butanol and the influence factors of reaction process have been also investigated. As a result, the optimal conditions of synthesis reaction have been obtained, reaction temperature is 110 °C , mole ratio of catalyst, glucose and n butanol is about 0.02∶1∶6. Under the optimal conditions, the reaction time 3h is much less than that reported in the literature. Products yield is about 88.1% and the product quality are very good.
