Outline of Final Research Achievements

Ionic liquid (IL) cosolvent systems can dissolve woody biomass under the mild conditions. Cosolvents increase solubilization efficiency and have superior cellulose-protective effects during enhanced dissolution of cellulose in IL.　Novel cellulose pretreatment solvent: phosphonium-based amino acid ionic liquid/cosolvent enhanced enzymatic hydrolysis of cellulose. Methyl β-D-glucoside was successfully synthesized at 40% yield from cellulose pretreated with tetrabutylphosphonium glycine/dimethyl sulfoxide, whereas the yield was only 1.4% from untreated cellulose.
