The effect of co-solvents, co-solvent-to-water ratio and temperature were studied. 2-MTHF proved to be effective co-solvent with water that significantly suppressed char formation and also demonstrated promising protection effect on monoaromatic compounds. The yield of solvolyzed lignin (SL) and char were in the range of 40.0–88.6{\%} and 10.4–0.1{\%} respectively, based on initial amount of dried lignin.
