摘要: 氨基纤维素是末端带有氨基的纤维素衍生物,化学结构与壳聚糖相似。氨基基团的引入使纤维素大分子具有很好的溶解性、成膜性和吸附重金属离子特性,并在酶的固定、药物缓释等生物领域有很好的应用前景。氨基纤维素的合成过程相对复杂,主要体现在中间产物的制备以及氨基纤维素的合成2个阶段,其合成过程的选择性和经济性较差,导致氨基纤维素的生产和应用受限。笔者主要对氨基纤维素的合成途径进行了综述,并对氨基纤维素的膜保护、固定酶和吸附等应用进行了总结。

Abstract: Amino cellulose is the cellulose derivative with terminal amino groups. The structure of amino cellulose is similar to that of chitosan. Because of the active amino groups in cellulose, amino cellulose exhibits good solubility, film-forming property, heavy metal ions adsorption property, and good application prospect in the field of biology such as immobilizing enzyme and controlling drug release. Now, the synthesis process is complicated, including the preparation of intermediate and the synthesis of amino cellulose. In addition, the poor selectivity and economics in the synthetic process of amino cellulose limit its applications. This paper mainly focuses on the preparation of amino cellulose, which includes the synthetic route, synthesis process conditions and synthetic prospect. At last, the applications of amino cellulose are discussed in detail, such as film-forming property, immobilization of enzyme, adsorption of impurities, and so on.

Key words: amino cellulose, tosylate, dissolve, synthesis, application
