| 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. |
