摘要:从离子液体结构、溶解反应条件对纤维素溶解的影响以及纤维素溶解前后的差异等方面总结了离子液体对纤维素的溶解能力,阐述了可能的溶解机理。从选取离子液体,确定反应条件的角度提出了提高纤维素溶解率的方法。介绍了以离子液体为溶剂制备磁性材料、吸附剂、生物膜等纤维衍生材料及其应用于相关领域的优势,展望了离子液体在制浆造纸废水处理、脱墨、制浆领域中的应用前景。提出了离子液体工业化存在的问题及离子液体的研究方向。
Abstract:A new type of environmentally friendly green solvents, namely ionic liquids (ILS) has many outstanding properties, making them promisingly employing in many fields. In this paper, the dissolution mechanisms of cellulose in ionic liquids were discussed. Firstly, it was necessary to clarify the relationships between cellulose solubility and ionic liquids structures, cellulose dissolution rate and dissolving conditions, and the dissolving effects on the cellulose. The methods to improve the dissolution rate based on the selection of ionic liquids and the determination of reaction conditions were recommended. Then, advantages of making fiber derivative materials, such as magnetic material, absorbent, biofilm using ionic liquids as solvent were expounded, and the application of ionic liquids in waste water treatment, deinking, pulping process of pulp and paper making field was prospected. Finally, the industrialization obstacles and research direction of ionic liquids were provided.
