| Outline of Final Research Achievements |
Xylan was selectively converted into furfural at the yield of 38.3% at 150℃ using 2-sec butylphenol as an extraction agent. Cedar was treated with 25vol% formic acid at 150℃, which resulted in saccharide yield of 46.4%. Then, saccharide was converted into HMF at the yield of 53.2 mol% using prepared reusable solid acid catalyst with an extraction agent. Furthermore, lignin-rich residue via formic acidic saccharification was treated with 30wt% acetone at 295℃, which resulted in 0.8 g/g-lignin yield of high functional lignin resin material.
