Outline of Final Research Achievements

It revealed that ionic liquids are effective reagents for the liquefaction of woody biomass without catalyst. They can liquefy all components of woody biomass such as cellulose hemicellulose and lignin. During liquefaction of woody biomass, depolymerization of them also occur. It is also found that these liquefaction and depolymerization of woody biomass with ionic liquids are not homogeneous, both from chemical and morphological viewpoints.
