Effect of Lewis acid catalysts on deep eutectic solvent extraction of elm wood lignin: process efficiency and structural modifications

Abstract In this study, a binary deep eutectic solvent (DES) system composed of choline chloride (ChCl) and formic acid (Fa) was employed, in combination with Lewis acid, which synergistically promoted the separation of lignin from elm wood. The results indicated that the catalyt...
