Lithium salts were dissolved in ionic liquid [Amim]Cl, and their dissolution behavior were tested by turbidimeter. It is found that the solubility of LiCl in [Amim]Cl is up to 14g/100g [Amim]Cl at 70°C, and it keeps growing as the temperature increase. Turbidity of cellulose solution in [Amim]Cl at 70°C was obtained, but the solubility of high concentration cellulose solution could not be demonstrated accurately in this way. Cellulose solutions with [Amim]Cl or [Amim]Cl/lithium salts as solvents at different temperature were obtained, in which the lithium salts were 1wt%(mass fraction of [Amim]Cl), polarization microscope was used to observe the dissolution behavior of cellulose. The solubility of cellulose would increased as temperature rose, and the solubility of cellulose in [Amim]Cl/1wt%LiCl reached 11.9%(mass fraction of [Amim]Cl) at 80°C, which was higher than in [Amim]Cl 9.4% at 80°C. It is found that the addition of lithium salts into [Amim]Cl can really improve the solubility of cellulose than in [Amim]Cl.
