With the full development and wide application of renewable green resources

cellulose derivatives are attracted more and more attention

and cellulose effective solvent cause widespread attention in the industry. Cellulose as the largest production in the nature of the polymer materials

reasonable utilization of cellulose is the most effective way to solve environmental and resource problems. Ionic liquids can dissolve well in cellulose

and it is also a good solvent of cellulose enzymatic hydrolysis reaction. Through the dissolution behavior of cellulose in ionic liquids

dissolution mechanism and degradation of cellulose enzyme action are discussed. The development prospects are proposed in the end.
