【摘要】 由于离子液体对于纤维素具有很好的溶解性能,以及离子液体本身所具有的热稳定性好、蒸气压低、不燃烧等优良性质,近几年以离子液体为溶剂制备纤维素衍生物的研究受到了越来越多的重视。综述了近期以离子液体为溶剂制备纤维素衍生物的研究进展,包括在离子液体中制备纤维素醋酸酯、琥珀酸纤维素、羧甲基纤维素等衍生化反应的特点,以及与传统制备方法的优劣对比等内容。更多还原

【Abstract】 For the excellent ability to dissolve cellulose,and their specialities such as good thermal stability, low measurable vapor pressure and nonflammability,the studies of application of ionic liquids to homogeneous function- alization of cellulose have attracted more and more attention.This paper reviews the achievements in the synthesis of cellulose derivatives in ionic liquids,including the properties of the homogeneous reaction such as carboxymethylation, acetylation and succinoylstion of cellulose,and the distinction compared with the conventional methods.更多还原
