Abstract: Provided is a method for producing a lignin degradation product that includes (1) a degradation step of degrading a raw material containing a plant biomass, in a mixed solvent of water and an aliphatic alcohol having from 4 to 10 carbon atoms, which separates into two phases at 0° C. or higher and 50° C. or lower, under the following conditions, and (2) after the degradation step, a liquid-liquid separation step of separating the lignin degradation product-containing organic phase from the solvent that has separated at the temperature for two-phase separation. The method produces a lignin degradation product at a high yield from lignin or a material containing lignin. Condition A: The concentration of the raw material to be in the mixed solvent is 1% by mass or more and 20% by mass or less. Condition B: The reaction temperature is 100° C. or higher and 350° C. or lower. Condition C: The reaction time is 0.1 hours or more and 10 hours or less.

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.
