“…DL-menthol with decanoic acid was used as the deep eutectic solvent and the proposed method was applied successfully, providing 88.8-105.9% relative recoveries. There were two common organic solvents, acetonitrile and butanol, extracted from aqueous solutions, with LLE and DES by Rabhi et al [118], by forming ternary systems.…”

The use of deep eutectic solvents (DES) is on the rise worldwide because of the astounding properties they offer, such as simplicity of synthesis and utilization, low-cost, and environmental friendliness, which can, without a doubt, replace conventional solvents used in heaps. In this review, the focus will be on the usage of DES in extracting a substantial variety of organic compounds from different sample matrices, which not only exhibit great results but surpass the analytical performance of conventional solvents. Moreover, the properties of the most commonly used DES will be summarized.

“…In particular, in ref , the possibility of using DES based on choline chloride for the extraction of ethanol from the ethanol–heptane system is presented. Much attention is focused on the extraction of 1-butanol from various systems using DES due to its promising potential for use in various industrial sectors, especially as a modern biofuel. − Authors of ref researched the separation of fuel additive isopropyl alcohol and ethyl acetate by various DESs and ILs. The separation of dimethyl carbonate and methanol azeotrope was studied by extractive distillation using deep eutectic solvents .…”

The current work is dedicated to the study of deep eutectic solvents (DES) as extractants for the purification of esters from alcohols. Separation efficiency of the mixture of 1-butanol−1-butyl formate using various deep eutectic solvents based on choline chloride with glycerol, ethylene glycol, urea, and glutaric acid was evaluated. The liquid−liquid equilibrium (LLE) data for the pseudoternary systems of 1-butanol−1butyl formate−deep eutectic solvents at 293.15 and 313.15 K and atmospheric pressure were obtained. The quantitative analysis was carried out using 1 H nuclear magnetic resonance (NMR) spectroscopy. The separation efficiency was evaluated based on the distribution coefficients and selectivity values. DES with urea and glycerol showed the highest separation selectivity, while DES with ethylene glycol and glutaric acid demonstrated the highest alcohol distribution coefficient. The reliability of the internal consistency of the liquid−liquid equilibrium data has been demonstrated by calculating the correlation equations of Othmer−Tobias, Hand, and Bachman. To confirm the experimental data, the LLE was calculated using the nonrandom two-liquid (NRTL) equation. It was shown that the standard deviation (σ) did not exceed 1.27%. A comparative analysis was carried out on the dependence of separation efficiency in other alcohol−ester systems using the same deep eutectic solvents.

“…COSMO-RS has been tested as a successful screening tool for several applications, i.e., for selecting organic solvents for extracting furfural and 5-hydroxymethylfurfural from water, ionic liquids for H 2 S capture, deep eutectic solvents (DES) for BTX (benzene, toluene, and xylene) extraction from aliphatics, and extracting solvents for solubilizing artemisin, among others. In fermentation processes, COSMO-RS model has been previously used for screening and solvent selection for the recovery of several classes of bioproducts such as 2-phenylethanol, , 2,3-butanediol, butanol, − 1,5-pentanediamine, succinic acid, , l -lactic acid, l -malic acid, and vanillin, using a wide range of solvents from conventional organic to tailor-made solvents such as ionic liquids or DES. Also, COSMO-based/Aspen Plus methodology is a tool that has allowed the computational design of different processes like the removal of H 2 S from flue gases using ionic liquids, the capture of siloxanes from biogas using ionic liquids, the optimal selection of solvents for aromatic/aliphatic separations, , ionic liquids for extracting the aroma 2-phenylethanol from water, etc.…”

Flavors and fragrances are important compounds used in the food, cosmetic, and pharmaceutical industries. They have an added value in the market when obtained through natural processes instead of synthetic routes. β-Ionone raises special interest if produced through a biotechnological process with genetically modified Sacharomyces cerevisiae, which is considered a natural production alternative. The main problem is that βionone is toxic to S. cerevisiae when its concentration increases in the fermentation broth. However, an in situ liquid−liquid extraction can alleviate the toxicity problem by removing the solute when it is produced. Thus, a screening of 6012 solvents for liquid−liquid extraction was performed by predicting the partition coefficient of β-ionone between an aqueous and an extracting organic phase using COSMO-RS. The best solvents for β-ionone extraction were selected after evaluating several parameters like solvent−water mutual solubility, solute extraction capacity, boiling temperature, thermophysical properties, and life cycle assessment of the solvent. The process was simulated and optimized in Aspen Plus V10 where in situ extraction was considered as a liquid−liquid extraction unit and the purification as two distillation towers in series. Then, a multicriteria decision-making analytical hierarchy process was performed based on the screening and simulation results with a subsequent sensitivity analysis. Finally, extracting solvents selected with the previous methodology were 2-methyl-2-butanol, 2-methyl-3-butene-2-ol, methyl isobutyl ketone, 1-pentanol, 1-octanol, myrcene, and n-decane, which were compared with the performance of dodecane, the benchmark extracting solvent used in the literature. Branched alcohols appear as a promising family of compounds for extracting β-ionone from aqueous phases.
