Research Abstract

Separation of biomass dissolved into ionic liquids using CO2 as antisolvent was studied. In the dissolution step, cellulose decomposed in some of the ionic liquids. However, ionic liquid, which was composed of acetate anion, showed negligible decomposition after 50 h at 40 ℃, regardless of whether it was pressurized or not. Gelation of cellulose-ionic liquid solution occurred at pressures 7 MPa, 25℃. Above 50℃, gelation did not occur. Viscosity of the solution decreased with increasing CO_2 pressure. Since gelation of cellulose with ionic liquid and CO2 occurs, separation of lignin from cellulose in actual biomass may be possible.
