Since the reactivity of lignin substantially depends on the structural heterogeneity and the type of functional group, the development of an effective technique converting heterogeneous lignin into well-defined compounds having uniform properties is required to utilize lignin as a sustainable source of bio-derived materials. In this study, we demonstrate tert-butoxide-catalyzed oxidation method to generate oligomeric lignin fragmentation from kraft lignin through the cleavage of the ether bond in lignin structure.
