摘要:
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.
