Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

open access: yesEnvironmental Progress &Sustainable Energy, Volume 45, Issue 2, March/April 2026.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...
