“…Not all the papers report the water content, but when they report low values, we observe a reasonable agreement with our measurements. In particular, our viscosity values are in agreement with measurements of Harifi-Mood (to within 6–8%) and Gurkan et al (∼−4%) and our previous measurements (to within 2–4%) for DES-A1 and with measurements of Vuksanović et al (to within 5–6%) for DES-B1. All of them report a water content below 0.1 wt %, but no trend in viscosity values with respect to the water content could be established between different sets of measurements; most likely, the trend is masked by the uncertainty of the viscosity measurements.…”

Deep eutectic solvents (DES) have emerged as promising 'green' solvents, but their successful industrial application requires relatively low viscosity. DES prepared from choline chloride and glycols offer such possibility. Viscosity and density are reported for a number of DES obtained by mixing choline chloride and a glycol (ethylene glycol, 1,2-propanediol, 1,3-propanediol, and 1,4-butanediol). The measurements were performed at 101.3 kPa, at temperatures between 293.15 K and 333.15 K, and for different mole ratios of the glycol and choline chloride. The viscosity was measured with a capillary viscometer, while the density was measured by means of a vibrating U-tube densimeter. The density and viscosity data have expanded relative uncertainties of 0.2% and 2.0%, respectively, with a coverage factor of 2. The viscosity of pure glycols was modeled using the extended hard-sphere (EHS) model that has its basis in kinetic theory and the molecular description of the fluid. Each DES was treated as a binary mixture, and the EHS model was used, with a mole average mixing rule, to calculate its viscosity. The measured DES viscosity data were represented with the average absolute deviation of 1.4% and a maximum deviation of 7%.

“…To date and to the best of our knowledge, there are no generalized models available for estimating the refractive indices of DESs. Some studies have been carried out in the field of refractive indices of DESs; however, in all of these studies, the main focus was the experimental measurement of the refractive indices, − with some studies also presenting empirical correlations as a function of temperature, which were fit to each of the investigated DESs, individually. − , This indicates that the proposed correlations are component-specific, being applicable to only the limited number of previously investigated DESs in the corresponding studies. However, Shahbaz et al published a study in which the molar refraction parameters of 24 DESs were calculated by applying the atomic contribution method proposed by Wildman and Crippen .…”

Generalized Model to Estimate the Refractive Indices of Deep Eutectic Solvents

et al. 2020

Reports on deep eutectic solvents (DESs), as a new category of green media following ionic liquids (ILs), are increasingly emerging in the literature. Because of the dramatically large number of DESs that will be introduced in the future, it would require much time and expense to experimentally measure their refractive indices. Therefore, proposing a global model that has the ability to estimate the refractive indices of various types of DESs is vital. In this study, it was the goal to develop an accurate, global, simple, and easy-to-use model for estimating the refractive indices of large numbers of DESs having different natures. With this idea in mind, a large up-to-date data bank for DESs was collected, consisting of 1203 data points from 153 different DESs, to develop the model. The proposed model requires critical pressure, molecular weight, and acentric factor as the input parameters. These parameters are calculated by suggested procedures. Therefore, in essence, to be used, the refractive index model does not need any experimental data. The overall absolute average relative deviation, AARD%, of the proposed model for all of the investigated DESs is 1.03%, which indicates high accuracy, as well as generality, for the estimation of the refractive indices of DESs.

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.
