“…VE is defined by the following Equation:VE=x1M1+x2M2ρmix−x1M1ρ1*−x2M2ρ2* where x1 and x2 are the mole fractions, M1 and M2 are molecular weights, and ρ1*, ρ2* and ρmix are the densities of Component 1, Component 2, and the binary mixture, respectively. Different DES–water binary mixtures show different VE features throughout the entire compositional range [139,140,141,142,143]. For instance, Kuddushi et al suggested that the negative VE<...>…”

Valorization of lignocellulosic biomass and food residues to obtain valuable chemicals is essential to the establishment of a sustainable and biobased economy in the modern world. The latest and greenest generation of ionic liquids (ILs) are deep eutectic solvents (DESs) and natural deep eutectic solvents (NADESs); these have shown great promise for various applications and have attracted considerable attention from researchers who seek versatile solvents with pretreatment, extraction, and catalysis capabilities in biomass- and biowaste-to-bioenergy conversion processes. The present work aimed to review the use of DESs and NADESs in the valorization of biomass and biowaste as pretreatment or extraction solvents or catalysis agents.

“…The latter is a challenge in the scale-up of processes, but can be tackeled by mixing with water. [15][16][17][18] Up to 50% of water the characteristics of DESs is preserved. In mixtures containing a lower fraction of DES (in the second step in the process described in this work, after adding ethanol and water) their properties are comparable with salt solutions.…”

“…In this work, 420 speed of sound data were collected from literature references, covering 39 different DESs [21,[30][31][32][33][34][35][36][37][38][39][40][41][42]. Table 1 lists these 39 DESs, including their corresponding HBAs, HBDs and molar ratios.…”

Deep eutectic solvents (DESs) are newly introduced green solvents that have attracted much attention regarding fundamentals and applications. Of the problems along the way of replacing a common solvent by a DES, is the lack of information on the thermophysical properties of DESs. This is even more accentuated by considering the dramatically growing number of DESs, being made by the combination of vast numbers of the constituting substances, and at their various molar ratios. The speed of sound is among the properties that can be used to estimate other important thermodynamic properties. In this work, a global and accurate model is proposed and used to estimate the speed of sound in 39 different DESs. This is the first general speed of sound model for DESs. The model does not require any thermodynamic properties other than the critical properties of the DESs, which are themselves calculated by group contribution methods, and in doing so, make the proposed method entirely independent of any experimental data as input. The results indicated that the average absolute relative deviation percentages (AARD%) of this model for 420 experimental data is only 5.4%. Accordingly, based on the achieved results, the proposed model can be used to predict the speeds of sound of DESs.
