“…In order to develop the GC and AC models, the most up-to-date databanks of various types of DESs were collected from the literature. The databanks involved 1239 data points from 149 DESs for density 35 – 66 , 1117 data points from 142 DESs for refractive index 11 , 39 , 41 – 43 , 47 , 50 , 54 , 57 , 59 , 63 , 64 , 67 – 87 , 461 data points from 24 DESs for heat capacity 59 , 70 , 88 – 93 , 398 data points from 37 DESs for speed of sound 42 , 43 , 67 , 72 , 75 , 77 , 82 , 94 – 100 and 538 data points from 98 DESs for surface tension 47 , 63 , 71 , 80 , 86 , 87 , 101 – 116 . All of the data were at atmospheric pressure.…”

The urgency of advancing green chemistry from labs and computers into the industries is well-known. The Deep Eutectic Solvents (DESs) are a promising category of novel green solvents which simultaneously have the best advantages of liquids and solids. Furthermore, they can be designed or engineered to have the characteristics desired for a given application. However, since they are rather new, there are no general models available to predict the properties of DESs without requiring other properties as input. This is particularly a setback when screening is required for feasibility studies, since a vast number of DESs are envisioned. For the first time, this study presents five group contribution (GC) and five atomic contribution (AC) models for densities, refractive indices, heat capacities, speeds of sound, and surface tensions of DESs. The models, developed using the most up-to-date databank of various types of DESs, simply decompose the molecular structure into a number of predefined groups or atoms. The resulting AARD% of densities, refractive indices, heat capacities, speeds of sound and surface tensions were, respectively, 1.44, 0.37, 3.26, 1.62, and 7.59% for the GC models, and 2.49, 1.03, 9.93, 4.52 and 7.80% for the AC models. Perhaps, even more importantly for designer solvents, is the predictive capability of the models, which was also shown to be highly reliable. Accordingly, very simple, yet highly accurate models are provided that are global for DESs and needless of any physical property information, making them useful predictive tools for a category of green solvents, which is only starting to show its potentials in green technology.

“…DES were prepared using the approach described by Hadj‐Kali et al 27 The hydrogen bond acceptor and hydrogen bond donor were mixed in HBA:HBD molar ratio at room temperature and pressure until a homogenous liquid was formed 28 . Prior to their use, the solution was kept for 4 h to attain equilibrium.…”

Densities of pure distilled water, tetra butyl ammonium bromide glycerol{[TBAB][Gly]}, and different concentration of aqueous bisphenol A (aq. BPA) (i.e., 25, 50, 75, and 100 ppm) were measured at different temperatures from 293.15–343.15 K. Further, densities of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} over the entire mole fraction were measured at different temperatures from 293.15–343.15 K. From these measured density data, the solution thermodynamic properties of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} were calculated, and the excess molar volume data were correlated using the Redlich–Kister polynomial equation. Furthermore, the σ‐profiles and σ‐potentials of all the studied species were generated and analyzied in terms of H‐bond donor and/or acceptor at atom and molecular levels. Finally, based on the results of aq. BPA with {[TBAB][Gly]}, tetra butyl ammonium bromide decanoic acid {[TBAB][DA]} and tetra butyl ammonium bromide oleic acid {[TBAB][OA]} based deep eutectic solvents were used for the removal of BPA from the aqueous stream at 298.15 K and 1 atm. This process was characterized in terms of distribution coefficient (D), extraction efficiency (η), and also thermodynamic feasibility of the process at different temperatures.

“…Sas et al focused on the elimination of phenolic pollutants from water reservoirs using organic acids and DESs based on menthol. The findings obtained from similar RTILs were compared with the experimental data and was shown to be more advanced [73]. Silva et al employed magnetic ionic liquids to identify organic pollutants in river water samples [74].…”

Ionic liquids as alternative solvents for energy conservation and environmental engineering

Because of industrialization and modernization, phenomenal changes have taken place in almost all spheres of life. Consequently, the consumption of energy resources and the cases of environmental hazards have risen to an unprecedentedly high level. A development model with due consideration to nature and an efficient utilization of energy sources has become the need of the hour, in order to ensure a sustainable balance between the environmental and technological needs. Recent studies have identified the suitability of ionic liquids (ILs), often labeled as ‘green solvents’, in the efficient utilization of energy resources and activities such as bio-extraction, pollution control, CO2 capture, waste management etc. in an environmentally friendly manner. The advent of magnetic ionic liquids (MILs) and deep eutectic solvents (DESs) have opened possibilities for a circular economic approach in this filed. This review intends to analyze the environmental and energy wise consumption of a wide variety of ionic liquids and their potential towards future.
