Preparation and Property of Starch Ester and its Development Progress Wang Shujun, Yu Jiugao Abstract Several preparation methods of starch esters and parameters
of influence on esterification are reviewed in recent years, these parameters are
temperature, concentration, pH and time et al, moreover, the properties of hydrophobicity,
thermal stability and paste viscosity are also introduced. At the same time, some
prospects on the development of starch esters are also put forward in the future. 淀粉酯的制备及性质 王书军 于九皋*(天津大学理学院 天津 300072) 摘要 本文详细综述了近年来淀粉酯的制备方法及制备过程中反应参数如温度、浓度、介质的pH和反应时间等对酯化反应的影响，并对淀粉脂肪酸酯的性质如疏水性、热稳定性，糊粘度等性质进行了概括。文章总结了淀粉脂肪酸酯制备的现状，并展望了未来的发展趋势。关键词 淀粉 淀粉酯 烷基脂肪酸 烯基脂肪酸 王书军 男，24岁，硕士生，现从事天然聚合物修饰改性的研究。*联系人 E-mail:davidwa@eyou.com2002-07-29收稿，2002-12-13修回 |
