Abstract:
The present invention relates to a method for producing lignin esterified with at least one fatty acid, wherein the method comprises the following steps: (i) reacting acetylated lignin with at least one fatty acid under the influence of heating and distilling at least part of the acetic acid formed during the reaction away from the reaction mixture, wherein per each mole of acetyl groups present in the lignin an excess molar amount of at least one fatty acid is used; and (ii) recovering lignin esterified with at least one fatty acid formed in step (i).
