Solvent fractionation of organosolv lignin to improve lignin homogeneity: Structural characterization

In this research work lignin was extracted from bamboo biomass by organosolv treatment method. The extracted lignin was further fractionated using ethanol and acetone to obtain lignin fractions especially suitable for new value-added applications. It is shown that the homogeneity and purity of lignin fractions namely, ETL (Ethanol treated lignin), ATL (Acetone treated lignin) and UDL (undissolved lignin) can be enhanced by sequential dissolution...
