纤维素的选择性氧化及发展趋势

摘要

纤维素是自然界取之不尽用之不竭的可再生资源,改变纤维素的结构,便赋予其许多新的功能。选择性氧化纤维素成为纤维素科学与纤维素基新材料研究领域中的热点。综述了纤维素的各种选择性氧化体系,重点介绍了TEMPO/NaClO/NaBr选择性氧化体系的反应条件、反应机理及最新的研究进展,并分析了氧化纤维素应用及发展前景。%Cellulose was the inexhaustible and renewable resource in nature. If its structure is changed, it will be many new functions. Selective oxidation cellulose has become the hot spot in the field of cellulose science and new materials based cellulose. This paper reviewed all kinds of the selective oxidation systems of cellulose. Especially it focused on the TEMPO/NaC10/NaBr selective oxidation system of the reaction conditions, reaction mechanism and the latest research progress. At the end of the paper, the application of oxidized cellulose and development prospect was analyzed.
