It has been known that the yield of lignin monomers during lignin depolymerization is limited by the irreversible condensations of lignin in the fractionation and/or depolymerization process. In this study, we report a new oxidative catalytic fractionation (OCF) process with a simple and effective one-pot but two-step approach to depolymerize lignin to lignin-derived chems. (LDCs) using polyoxometalate (POM) as the only catalyst. First, the POM effectively catalyzed the methoxylation of the active α-OH groups of lignin in a methanol and water mixture at low temperature (100°C), and 96% of the stabilized lignin in the lignocellulose sawdust was extracted to the solution simultaneously. Then the lignin solution was heated to an elevated temperature (140°C) in the same solvent. As a result, 74.0 weight % of the lignin (based on the weight of the Klason lignin in the wood) was converted to LDCs, including 45.9 weight % aromatic monomers.
