高碘酸盐氧化纤维素与双醛纤维素衍生反应及应用研究进展

Research Progress in Derivative Reaction of Dialdehyde Celluloseand Its Application

高碘酸盐氧化纤维素反应条件温和,反应生成的双醛纤维素含高反应活性的醛基,能够发生还原、磺化、氧化、胺化等反应,得到各种纤维素衍生物。该文主要介绍了高碘酸盐氧化纤维素的反应特征、双醛纤维素的衍生反应、高碘酸盐氧化法制备纳米纤维素的方法及双醛纤维素及衍生物在生物医药和废水处理等领域的应用。

Cellulose can be oxidized by periodate under mild condition.The dialdehyde cellulose contains the reactive aldehyde groups,which can bereduced,sulfonated,oxidized and aminated to obtain cellulose derivatives.This paper mainly introduces the characteristics of periodate oxidation reaction,the derivatization reaction of DAC,the preparation of nanofibers by periodate oxidation and derivative reaction,and the application of periodate oxidation and derivative reactionof dialdehyde cellulose in the field of biopharmaceutical and wastewater treatment etc.
