Abstract

Deep eutectic solvents (DESs) are new sustainable and cheap reaction media combining the features of both ionic liquids and organic solvents. They are made up by association of hydrogen-bond donors and hydrogen-bond acceptors, and they can promote the hydrolysis of lignocellulosic bonds. Herein the microwave-assisted treatment of waste wood flours with a DES constituted by choline chloride and oxalic acid to get a cellulosic residue separated from lignin degradation products is reported. The insoluble deposit is characterized by SEM, TGA, DSC, FTIR-ATR, and H-1-C-13 CP/MAS NMR techniques and can be available for further uses such as nanocellulose production.
