| 摘 要： | 以从麦草中分离得到的木聚糖为原料、丙烯酰胺为醚化剂、碱为催化剂、丁醇/水为反应介质制备了带有高取代度双官能团的木聚糖衍生物.采用13C核磁共振表征了木聚糖衍生物的结构.利用平行板流变仪和同步热分析仪对木聚糖衍生物与原木聚糖的动态流变性能和热稳定性进行测试,结果表明:与原木聚糖溶液相比,木聚糖衍生物溶液呈现较低的粘度,剪...

| Abstract: | Bifunctional xylan derivatives(XDs) with high degree of substitution were prepared from native xylan in wheat straw,with acrylamide as the etherifying agent,alkali as the catalyst,and butanol/water mixture as the reaction system.Then,the structure of the products was characterized by means of 13C NMR.Moreover,the dynamic rheological behaviors and thermal stability of XDs and the native xylan were tested by using a parallel-plate rheometer and a simultaneous thermal analyzer,respectively.The results show tha... |
