摘要
本文综合研究并分析了具有不同官能团和功能模式的纤维素衍生物的制备方法,同时也总结评价了可被用来作为均相反应介质的各种溶剂,并举例说明了棉纤维素酯非均相制备方法。另外,总结了这些年来在纤维素衍生化中应用的新试剂,给出了区域选择性酰基化反应的几个最新例子,对今后纤维素科学研究提出了发展的方向。
This paper gives an overview of synthesis paths recently studied for the preparation of cellulose esters. A classification of solvents that can be applied as medium for homogeneous reactions is given and different types of solvents, namely both aqueous and non-aqueous non-derivatives, ionic and non-ionic ethers of cellulose are included. Moreover, the heterogeneous reaction is also addressed. In addition, a number of new synthesis methods for the derivation of cellulose both on the repeating unit and along the polymer chain are briefly reviewed. Some latest examples of regioselected functionalized cellulose derivatives are also given. The direction of the cellulose esters sciences is also put forward here.
