METHOD TO PRODUCE BIOMASS-DERIVED COMPOUNDS USING A CO-SOLVENT SYSTEM CONTAINING GAMMA-VALEROLACTONE

摘要

A method to produce an aqueous solution of carbohydrates containing C5- and/or C6-sugar-containing oligomers and/or C5- and/or C6-sugar monomers in which biomass or a biomass-derived reactant is reacted with a solvent system having an organic solvent, and organic co- solvent, and water, in the presence of an acid. The method produces the desired product, while a substantial portion of any lignin present in the reactant appears as a precipitate in the product mixture.
