摘要： A method of preparing a low-molecular lignin derivative comprises the step of: preparing lignin by hydrolyzing lignocellulosic biomass with an acid; preparing a first mixture by mixing 100 parts by weight of the lignin and 500 parts or more by weight of a phenolic compound; preparing a second mixture by mixing the first mixture with a solvent including the hydrophobic polar solvent; and recovering a low-molecular lignin derivative from the second mixture.
