Lignin is the largest nature source of renewable material with an aromatic skeleton and thus a potential source for a range of value-added chemicals/products. Developing novel solvent systems for selectively extracting lignin from biomass and for lignin conversion to value-added chemicals have gained increasing interest recently.

In this presentation, we will report current progress from our group on developing a new type of solvent for selective remove of lignin from woody biomass including Douglas fir and Poplar. Detailed characterization of lignin properties and investigation of its potential for conversion to value-added chemicals will be presented.
