Amino Acid-Based Deep Eutectic Solvents in Biomass Processing - Recent Advances

The use of non-conventional solvent systems, such as deep eutectic solvents (DES), for biomass processing is a growing interest. DES are formed by two or more components, usually solids at room temperature, which can interact with each other via hydrogen bonding, from bond acceptor (HBA) and donor (HBD), resulting in liquid phase. most studied HBA the literature choline chloride several HBD their have been extensively reviewed. However, abundant natural be successfully applied on preparation different DES, e.g., amino acids. These acid-based used pretreatment, providing fractionation main macromolecular components lignin solubilization. In addition, chemical conversion to obtaining platform chemicals furanic derivatives. Bearing this mind, review focuses exploring processing, pretreatment conversion.
