A novel ternary system consisting of deep eutectic solvent-alcohol (DES-OL) mixture was developed for the effective delignification of lignocellulosic biomass. Optimization studies included selecting suitable co-solvent (among n-BuOH, n-PrOH & EtOAc) for treating biomass (rice husk, rice straw and wheat straw), altering the DESto-alcohol ratio (2:1, 1:1 and 1:2) as well as the reaction temperature (50, 80 and 120 degrees C). The highest delignification (similar to 50%) was observed using n-butanol assisted DES (ChCl: OA) at a ratio of 2:1, with high solid loading of 15% (w/v) at 120 degrees C (similar to 1.2 bar) in a 60 min reaction. Post pretreatment, high purity lignin was recovered after distilling off butanol for recycling. Microscopy and CPMAS/NMR studies confirmed the effectiveness of DES-OL pretreatment on biomass delignification.
