【摘要】 以马铃薯淀粉、乙二醇、十二醇为原料,对甲苯磺酸和助剂P为复合催化剂,采用转糖苷化反应合成烷基糖苷表面活性剂,探讨了各主要影响因素对合成反应过程及结果的影响。通过正交实验法优选出最佳工艺条件:糖苷化温度115℃;n(经折合的淀粉中葡萄糖单元):n(乙二醇):n(十二醇):n(催化剂)=1∶5∶3∶0.01。在此条件下总糖苷收率为122.53%。更多还原

【Abstract】 The alkyl polyglycoside was synthesized by trans-glycosidation of potato starch,ethylene glycol,n-dodecanol in the presence of a compound catalyst of p-toluenesulfonic acid and promoter P,and influence factors of the synthesis process were also studied.The optimum conditions obtained by the orthogonal design were as follows: glycosidation temperature 115℃,n(glucose unit of starch) : n(ethylene glycol) : n(n-dodecanol)∶n(catalyst) =1∶5∶3∶0.01.The yield was 122.53%.更多还原
