Therefore, finding new routes to utilize Kraft lignin (KL) as a renewable raw material for the chemical industry is of significant economic and environmental importance. Herein we report a novel, two-step procedure for facile synthesis of vanillin from technical KL by combining solvent fractionation and catalytic oxidation r...
