新型表面活性剂——烷基糖苷的合成与应用研究

以EDTA、十二烷基苯磺酸钠和磷酸为主要成份的复合催化剂，采用直接苷化法了十二烷基葡萄糖苷（C12－APG），考察了此非均相反应体系中的反应温度、反应时间、催化剂用量以及醇糖比对反应过程的影响，实验结果表明，在最佳的工艺条件下，反应时间为3．5h，糖苷得率可达到132．4％，并对其重用机理和所合成糖苷的应用性能了进一步探讨。

Study of the synthesis and application of alkyl polyglucosides

In this article,dodecyl-polyglucoside was synthesided by the direct reaction of glucose and laurel alcohol useing a complex catalyst consist of the EDTA,C 12 -LBS and phosphori acid A process for synthesis C 12 -APG at different reacting temperature,time,catalyst and ratio of dodecanoland glucose was studied.Experiment show,at the better reaction condition,obtainable glucoside yield 132 4 % when reactive time was 3 5 h.Action mechanism and application properties of the APG was discussed
