摘要
研究了淀粉和乙二醇在酸性催化剂及助催化剂存在下一步直接合成乙二醇葡萄糖苷的工艺 ,考察了影响反应和产品性能的多种因素。在较适宜的工艺条件下 ,研究了该反应的机理 ,提出了由淀粉和乙二醇直接法合成乙二醇葡萄糖苷的宏观动力学模型 ,该过程为表观拟零级反应求取了模型参数 。
Alkyl polyglucoside (APG) products are a new type of non-ionic surfactant which possess high foaming power, emulsifying properties, softening and detergent properties, and low irritating properties, etc. The new process of preparing glycol polyglucoside by starch and glycol in the presence of an acid catalyst and a catalyst promoter through one step reaction has been studied. In the process, influences of various factors, for example, reaction temperature, pressure and time, amounts of catalyst and its auxi...
