Abstract:
Provided is a method of producing a purified lignin, including: treating a plant biomass in a first solvent mixture formed of water and a first organic solvent under specific conditions; subjecting a solid fraction insoluble in a first solution mixture and the first solution mixture to solid-liquid separation after the treatment; mixing the first solution mixture from which the insoluble solid fraction has been separated, and a second organic solvent excluding the first organic solvent and having a dipole moment of 0.25 d or less to provide a second solution mixture; and subjecting a solid fraction insoluble in the second solution mixture to solid-liquid separation to extract the purified lignin in a liquid phase of the second solution mixture.

Claim (Index 4):
A method of producing a purified lignin, comprising:\n mixing a raw material lignin solution, and at least one solvent (a) selected from water and a hydrocarbon having a dipole moment of 0.25 d or less to provide a solution mixture; and subjecting a solid fraction insoluble in the solution mixture to solid-liquid separation to extract the purified lignin in a liquid phase of the solution mixture.
