Abstract: A new ionic liquid Cl2 was synthesized. The solubility property of microcrystalline cellulose in this ionic liquid was preli minarily studied. The influence of different factors on its solubility was investigated by orthogonal test. The optimal conditions were:15% NaOH solution for cellulose activation, 80℃ for dissolving cellulose, 60 min of dissolving time, and anhydrous condition of the ionic liquid for the test. The results show that the ionic liquid has a certain ability to dissolve microcrystalline cellulose. The dissolution mechanism was also prelimnarily discussed.

Key words: microcrystalline cellulose, ionic liquid, solubility property
