“…Another feature of NBSs is their low cost and natural abundance while ILs and DESs are generally expensive and require industrial processes. In addition to LIBs recovery, NBSs could be biomass utilization, gas capture/conversion, material synthesis, catalysis, and electrolytes, just like ILs and DESs. ,,− …”

Water, supercritical fluids, ionic liquids, and deep eutectic solvents have been deemed as traditional green solvents. The increasing demand for sustainable development necessitates the exploration of innovative green solvents due to some disadvantages of the traditional green solvents. In this regard, a novel concept of “natural biomass soups (NBSs)” is introduced to be eco-friendly alternatives to traditional green solvents. NBSs represent the solvents directly prepared from natural biomass without any additional industrial purification, rendering the advantages of being cheap, simple, green, biocompatible, natural, tunable, and task-specific and avoiding the usage of any additional solvents/catalysts/additives. An exemplary application of NBSs involves their exceptional ability to efficiently extract metals from lithium-ion battery cathodes at mild temperatures. NBSs have the potential to replace ionic liquids and deep eutectic solvents and significantly expand the realm of green solvents and green chemistry.

“…Deep eutectic solvents (DESs) are a family of environmentally friendly solvents proposed by Abbott et al in 2003 . Such materials are composed of an ionic compound such as a quaternary ammonium salt and a molecular compound such as a polyol, which can replace traditional organic solvents and ionic liquids. − To date, DESs have gradually become an important choice in polymer solution processing and have been widely used in electrodeposition, extraction separation, catalytic reactions, nanomaterial preparation, and many other fields. , In terms of chemical fiber surface modification, our previous work confirmed that DESs have a dissolution etching effect on the surface of the polyester fiber, forming a super hydrophilic surface …”

Poly(lactic acid) (PLA) is considered the best candidate biobased material alternative to petroleum-based polyethylene terephthalate due to its renewability and biodegradability. However, the crucial dyeing issue of PLA filament limits its applications in the textile industry. Herein, a green deep eutectic solvent (DES) consisting of choline chloride and oxalic acid was employed for the surface reconstruction of the PLA filament. Owing to the synergistic contribution effect of physical etching and chemical modification from the DES, the surface roughness and chemical activity of the PLA filament improved significantly, thereby conferring potent low-temperature dyeing performances. The DESmodified PLA filament can achieve K/S value and dye uptake at 90 °C commensurate to those of the PLA filament at 110 °C with no decay on the dry and wet rubbing fastness. This work demonstrates a promising approach for the low-temperature dyeing of PLA filaments, enabling the practical applications of PLA filaments.

“…Of the developed solvent systems, deep eutectic solvents (DESs) have been recognized as an emerging class of functional solvents for the dissolution of lignocellulosic components. Generally, DESs are composed of two components via the hydrogen bonding interaction to generate a eutectic mixture, and the two components are hydrogen-bond donor (HBD) and hydrogen-bond acceptor (HBA), respectively. , The DESs designed by selecting suitable HBDs and HBAs of different properties could enable them to possess various unique advantages, e.g., strong solvation ability, good designability, low cost, facile preparation, high biocompatibility, etc. − These characteristics of DESs promote the continually growing interest in constructing efficient DESs to dissolve cellulose, hemicellulose, or lignin. − As reported, DESs can be defined as the mixture of two or more pure compounds with a eutectic point temperature below that for an ideal liquid mixture, showing significantly negative deviations from ideality . More importantly, the composition of DESs should be in a certain range, not just in a fixed stoichiometric proportion .…”

Deep eutectic solvents (DESs) have attracted significant interest in dissolving lignocellulosic components. However, revealing the relationship between the solvation properties of DESs and their ability to dissolve lignocellulosic components remains a significant challenge. Herein, 56 DESs were prepared and applied to dissolve lignocellulosic components. This revealed that the Kamlet−Taft parameters (i.e., α, β, and π*) were significantly affected by the structures of DESs. More notably, the correlation between Kamlet−Taft parameters and solubility varied with DESs and lignocellulosic components. Concretely, DESs have greater values of β and β−α (net basicity), are expected to dissolve cellulose efficiently, have greater net basicity, and are favorable to dissolve lignin, and the solubility of xylan was linearly correlated with the β value. These findings provided valuable information and necessary theoretical guidance on designing robust DESs to dissolve lignocellulosic components based on Kamlet−Taft solvatochromic parameters.
