    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.

    Abstract: A thermosetting resin composition according to the present invention contains: purified lignin obtained by treating a herbaceous biomass as a raw material under the following conditions in a first solvent that is a mixed solvent of water and at least one type of alcohol selected from aliphatic alcohols having 4 to 8 carbon atoms, subsequently removing the alcohol from the alcohol phase that is separated at the temperature at which the first solvent separates into two phases to give lignin, adding a second solvent that is an organic solvent alone or a mixed solvent of the organic solvent and water to the resultant lignin, and removing the second solvent from the solution in which the lignin is dissolved in the second solvent; and a lignin-reactive compound that has a functional group capable of reacting with the purified lignin. Condition A: the concentration of the raw material to be charged into the mixed solvent is 1% by mass or more and 50% by mass or less. Condition B: the treatment temperature is 100° C. or higher and 350° C. or lower. Condition C: the treatment time is 0.1 hours or more and 10 hours or less.
