摘　　要：本文概述了近十年来纤维素在均相体系中化学改性的研究成果,重点介绍了纤维素在氯化锂/N,N-二甲基乙酰胺(LiCl/DMAc)、二甲基亚砜/三水合四丁基氟化铵(DMSO/TBAF3H2O)、离子液体、碱/尿素体系中的均相酯化、醚化以及接枝共聚合反应.同时,总结了纤维素在这些溶剂中的反应特性及其衍生化产物的结构、性质和应用.Cellulose, as an environmentally friendly renewable been investigated extensively by both academic and industrial resource, has received more and more attention. It has researchers Because of the depletion of oil resources, the increasing pollution of the environment and the urgent need for sustainable development. Based on the unique structure and reactivity of cellulose, chemical modifications play dominant roles in improving the overall utilization of this bioresource. Cellulose derivatives have been found in numerous applications in a variety of fields, including the paper and textile, food, cosmetics, chemical, and pharmaceutical industries. Moreover, homogeneous modification of cellulose has been one focus of cellulose research for a long time. In this review, research development of chemical modification of cellulose in the homogeneously systems in the recent 10 years was summarized and 155 references were cited. Esterification, etherification and graft copolymerization of cellulose in LiC1/N,N-dimethylacetamide, dimethyl sufoxide/tertrabutylammonium fluoride, ionic liquids, and NaOH/urea aqueous solutions have been described in detail.
