新型表面活性剂烷基糖苷的合成研究

Preparation of the Surfactant Alkyl Polyglucoside from Starch

以葡萄糖、月桂醇为原料 ,采用直接法合成了十二烷基葡糖苷 ,研究了催化剂用量、原料配比、反应温度和反应压力等对产品得率的影响 ,得出较佳工艺条件为 :剂糖比 0 .0 0 8∶ 1,温度 12 0℃ ,醇糖比 5∶ 1、压力 4.0 0 k Pa,反应时间4h,此时 APG得率为 15 8.7%。并对产品的表面张力和起泡性质进行了测定。

In this paper,dodecyl polyglycoside were synthesized by the direct catalysis with lauryl alcohol and glucose.The influence factors for reaction,such as catalyst quantity,raw material ratios,reaction temperatures and reaction pressure ect are discussed in detail. and measured the properties of surface tension and foaminess.
