| Outline of Final Research Achievements |
Conversion of lignocellulosic biomass into chemicals has greatly attracted attention for establishing the sustainable society because of the abundance and renewability of the lignocellulose. One-pot conversion of cellulose into isosorbide, which is a promising monomer of heat-resistant polymer, has been reported using combination of supported metal catalyst and homogeneous acid such as sulfuric acid. In this study, we investigated conversion of cellulose into isosorbide without homogeneous acids.
We have succeeded in one-pot conversion of cellulose into isosorbide with 55.8% yield by a supported ruthenium catalyst and Amberlyst 70 in water. It has been demonstrated that the direct catalytic conversion of cellulose into useful chemicals is a powerful technique for the use of lignocellulosic biomass.
