Rapid Decomposition of Cellulose Dissolved in Ionic Liquid Using Gas–Liquid Interface Discharge

Shoichiro Furukawa; Nobuhiro Inoue; Toshio Ishioka; Kenji Furuya; Akira Harata

Cellulose was dissolved at 3 wt % in 15 mL of 1-allyl-3-methylimidazolium chloride ([Amim]Cl) together with 2 wt % water, and then gas–liquid interface discharge was carried out at 20 W for 200 s. As a result, 7.6% of initially dissolved cellulose decomposed and 3.9% of initially dissolved cellulose changed into reducing sugar. Adding a small amount of water to the solution was essential for the decomposition of cellulose. [Amim]Cl was stable against the discharge, as determined from the NMR signals measured before and after the discharge.
