In-depth 2D-NMR characterization of lignin and hemicellulose degradation products in recovered acidic deep eutectic solvent.
Deep eutectic solvents (DESs) have gained popularity for their ability to selectively fractionate lignin and hemicelluloses from lignocellulosic biomass. Recent work has focused on the recovery and reuse of DESs for multiple iterations, in some cases implicating accumulated impurities as the reason for declining pulpin...
