Abstract:Deep eutectic solvent (DES) as one of new kinds of green solvent, exhibited easy availability, low cost, good biocompatibility, recyclability, strong molecular polarity and designability. It was used in wide areas including biorefinery, catalysis, biomass conversion and functional materials manufacturing. Therefore, based on the recent research reports on the application of DES pretreatment in lignocellulose biorefinery, this review mainly focused on the dissolution mechanism, influencing factors and separation efficiencies of cellulose, hemicellulose and lignin by separate or cooperative pretreatment of DES with different compositions and properties. The advantages, disadvantages and development status of the functionalization and high-value utilization of DES-fractionated components of lignocellulose were also discussed. It was expected to provide some new insights/inspirations for comprehensive and efficient utilization of DES to promote the research and application of lignocellulosic biomass refining. |
