摘要研究了十二醇中葡萄糖在Fischer糖基化反应条件下的声化学聚合产物的结构。观察到聚合度高达23的低聚物，与经典加热相比，超声催化反应的平均值更高，正如使用MALDI-TOF技术的质谱所揭示的那样。脱水末端单元的存在也通过该方法确定。糖苷键的类型和分支比进行了评价后，化学降解的低聚物。
Abstract The structure of glucose oligomers obtained by sonochemical glucose polymerization in dodecanol under Fischer glycosylation conditions was investigated. Oligomers having a degree of polymerization up to 23 were observed, with a mean value higher for the sonocatalyzed reaction compared to classical heating, as revealed by mass spectroscopy using the MALDI-TOF technique. The presence of anhydro terminal units was also ascertained by this method. Glycosidic bond types and branching ratios were evaluated after chemical degradation of the oligomers.
