主　　题：Deep eutectic solvent(DES) Choline/L-Lysine hydrochloride Wheat straw Natural cellulose Solvent 

摘      要：Green solvents for cellulose dissolution is a key topic for green chemistry,especially natural cellulose with high molecular weight,and there are scarce solvents *** eutectic solvent(DES)is a typical kind of green solvent that has been attracted much attention ***,high molecular weight natural cellulose(DP3000)was first isolated from wheat straw and then be directly dissolved in the choline/L-lysine(Ch/Lys)*** solution owns excellent stability,and the solubility reaches^5%.Rheological studies revealed that the natural cellulose can be well dispersed in the DES solution and showed gelation at high *** dissolved cellulose can be regenerated when the dilute acid aqueous solution was added into the *** provides an energy conversation and an environmentally friendly route to prepare a cellulose solution,which makes it possible to convert cellulose to valuable chemicals and materials in its homogeneous solution.
