摘要
本文采用半干法制取高取代度季铵型阳离子淀粉,并对高取代度季铵型阳离子淀粉的合成原理和合成条件进行研究,通过实验,分析讨论反应温度、碱的用量及反应介质条件等因素对阳离子取代度及产品性能的影响,选择并确定反应的最佳条件。
Literary grace this fetch with half-dried legal system high to replace degrees of cation starch,And to high to replace degrees of cation synthetic terms of starch study.Pass the experiment,Analyse and discuss that reflects the quantity of the temperature,alkali and react medium terms,etc.factor replace degree and influence of properties of product to cation, Choose and confirm the optimum condition reacting.
