The increasing global levels of anthropogenic greenhouse gases (GHGs), especially CO2 emissions, have caused environmental problems that impact humanity and the ecosystems. Therefore, gas capture and storage are a feasible solution to this global issue. Some aqueous amine solutions, such as monoethanolamine (MEA), have been used to capture GHGs, but they are not environment friendly. Research on greener solvents for this task led to deep eutectic solvents (DESs) as a novel option. This review explores the applications of different DESs; compares the differences between gas solubility methodologies; and studies the interference of the DESs’ molar ratio, the influence of HBA and HBD, and the differences between the solubility of some gases in these solvents. More than 40 DESs have been analyzed; however, some gaps need to be filled, such as data for gas solubility under higher pressures and thermodynamic modeling of experimental data.

D-limonene is a monoterpene naturally found in citrus peels, especially lemons and oranges, and is responsible for their strong odour. D-Limonene has specific properties that enable its use in various industrial segments such as foods, perfumes, beverages, cosmetics, pharmaceuticals, detergents, soaps, insecticides, disinfectants, fine chemicals, as a biodegradable solvent, and so on. Among the ways in which limonene can be used, the mixture of d-limonene with alcohol compounds has a great application potential, since alcoholic extracts of citrus essential oils have high solubility in aqueous solutions, reducing the occurrence of oxidation reactions as well as increasing the aromatic resistance of the mixture. However, studies on the thermodynamic properties of alcohol compounds and terpenes mixtures are still scarce. Thus, in this study, the density (ρ) and excess molar volume data (VmE) of seven binary mixtures of d-limonene with 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-octanol, 1-decanol and 1-dodecanol were determined at 298.15 K and throughout the whole mole fraction range. The flash point (FP) of these same mixtures was also determined from the 0.0 to 1.0 mol fraction range. The FP experimental values were compared to FP values calculated using Liaw’s approach and the activity coefficient models UNIQUAC, NRTL, UNIFAC and Ideal, with an average deviation of (0.55, 0.57, 1.43 and 4.02) K, respectively. The interaction parameters of the models UNIQUAC and NRTL were thus shown to be well adjusted and provide a better description of the FP behaviour than the ideal and UNIFAC models, as expected. The excess molar volumes calculated with use of density determination were all positive, indicating that the molecule interactions in the mixtures are weaker than those in the pure components causing an expansion of excess molar volume (>0). This behaviour was also corroborated by the activity coefficients calculated.

Aqueous two-phase systems (ATPS) formed by Protic Ionic Liquids (PILs) are a potential alternative to recovery PILs after their use in pretreatment step and valorization of lignocellulosic biomass. Besides, ATPS based on PILs may be applied to Kraft lignin fractionation toward a more sustainable environment. In this study, nine alkanolammonium-based PILs were synthesized using organic acids (formic, acetic, propionic, lactic, and glycolic) as precursors. These PILs were combined with acetone to form ATPS at low temperatures, and the partition of Kraft lignin was tested using these same systems. The presence of an extra hydroxyl group in the PILs’ anionic part increased their ability to form ATPS, due to the increase in their acidity. Also, increasing the alkyl chain length of the PILs’ anionic part impairs the formation of ATPS. In contrast, the behavior was observed for the cationic part, due to the increase in the PILs’ hydrophobicity nature. Regarding the partition of Kraft lignin applying 2-hydroxyethylammonium-based PILs, the increase in the alkyl chain length of the PILs’ anionic part leads to stronger PILs-lignin interactions, which favored the lignin’s migration to the bottom phase (PILs-rich phase), and lower partition coefficient values, as follows: formate < acetate < propionate anions. The presence of an extra hydroxyl group in the PILs’ anionic part (lactate and glycolate-based PILs) impaired PILs-lignin interactions, and consequently, increased the partition coefficient, compared to propionate and acetate-based PILs. Finally, the increase in the PILs’ cationic part leads to the improvement in PILs-lignin interactions, and lower partition coefficient values were observed, following the sequence for lactate-based PILs: tris(2-hydroxyethyl)ammonium < bis(2-hydroxyethyl)ammonium < 2-hydroxyethylammonium; and the following sequence for propionate-based PILs: tris(2-hydroxyethyl)ammonium ≈ bis(2-hydroxyethyl)ammonium < 2-hydroxyethylammonium. The glycolate-based PIL showed the highest partition coefficient value, which is related to its small alkyl chain length and the presence of an extra hydroxyl group, making PIL-lignin interactions weaker. The results showed that acetone emerges as a phase-forming agent to remove, at least partially, the lignin dissolved in PILs aqueous solutions, allowing their recycle and reuse after the pretreatment step, for example. Finally, the NRTL activity coefficient model was used to correlate tie-line compositions, and the interaction parameters were estimated for each system determined.

The application of eutectic solvents (ESs) in lignocellulosic biomass fractionation has been demonstrated as a promising approach to accomplish efficient and environmentally friendly biomass valorization. In general, ESs are a combination of two components, a hydrogen-bonding donor and a hydrogen-bonding acceptor, in which the melting point of the mixture is lower than that of the individual components. However, there are plenty of possible combinations to form ESs with the potential to apply in biomass processing. Therefore, the development of fast and effective screening methods to find combinations capable to dissolve the main biomass components—namely cellulose, hemicelluloses, and lignin—is highly required. An accurate and simple technique based on optical microscopy with or without polarized lenses was used in this study to quickly screen and monitor the dissolution of cellulose, xylose (a monomer of hemicelluloses), and lignin in several ESs. The dissolution of these solutes were investigated in different choline-chloride-based ESs (ChCl:UREA, ChCl:PROP, ChCl:EtGLY, ChCl:OXA, ChCl:GLY, ChCl:LAC). Small amounts of solute and solvent with temperature control were applied and the dissolution process was monitored in real time. The results obtained in this study showed that cellulose was insoluble in these ESs, while lignin and xylose were progressively dissolved.

This work evaluates the potential use of 2-hydroxy ethylammonium-based protic ionic liquids (PILs) for dissolving the major lignocellulosic biopolymers such as cellulose, xylose and lignin. Three PILs, 2-hydroxy ethylammonium formate (2-HEAF), 2-hydroxy ethylammonium acetate (2-HEAA) and 2-hydroxy ethylammonium propionate 2-HEAPr, were synthesized and characterized (viscosity, density and conductivity). A small amount of biopolymer was added to the PILs; the biopolymers’ dissolution curves were determined from 30 °C up to 100 °C on these solvents using a hot stage coupled to an optical microscope. The results show that while xylose and lignin could be dissolved by the PILs, cellulose could not, and also that 2-HEAF—which presented the higher ionicity—was the most appropriate PIL among those tested to dissolve these biopolymers (xylose and lignin). They also show that lignin dissolution is faster when an anion with a short alkyl carbon chain is used and that higher heating rates require a somewhat higher temperature to achieve full dissolution.

The flash point (FP) of binary mixtures formed by fatty acid methyl esters (FAMEs), which are the major compounds of methyl biodiesel, is investigated in this study, and the nonideality of the liquid phase was calculated with the ideal model, UNIFAC, UNIFAC-Dortmund (UNIFAC-Do), and NIST-UNIFAC models. The different models used to calculate the activity coefficient were compared through the FP result that was estimated using Liaw’s approach. The experimental results show that the larger the carbon chain of FAME is, or the richer the solution in the heavier compound is, the higher the FP of the compound and solution is. The results also show that the ideal model is the best one between those tested in this study because the solutions studied here can be considered ideal, and the calculated FP temperature of the binary mixtures presented an average root-mean-square deviation equal to 0.67% using this model. It was observed as an abrupt decrease in the FP value of the mixture with small addictions of the light compound in the region that is rich in the heavier compound, remarkably when the difference in the length of the alkyl carbon chain of these components is large. This behavior is an important factor that must be considered in safety and transportation cases.
