Acidic ionic liquids, which have acidic part in the structures, are known as efficient catalysts for hydrolysis of cellulose, compared to H2SO4.1) However, even when the acidic ionic liquids are used, glucose yield is still not sufficient (40 to 50%). To increase the yield of glucose, we here developed a successive treatment system, i.e. pretreatment by sulfuric acid and hydrolysis by acidic ionic liquid in this study. Decrystallization of cellulose can be easily achieved by immersion in concentrated sulfuric acid. After the decrystallization, acidic ionic liquids can be synthesized in situ just by addition of zwitterions because acidic ionic liquids are composed of sulfuric acid and zwitterion (Figure 1). Furthermore, we suggested electrodialysis as a methodology for separation of the acidic ionic liquid to sulfuric acid and zwitterion for reuse.
