“…A positive contribution was observed on adding Glyceline, which indicates a weak dipole-dipole interaction between the constituents' molecules of the mixture. Furthermore, the positive contribution is attributed to the disruption of the ordered structure of pure the component during the formation of the mixture [24]. This means that there is a disruption of the ordered structure of pure Reline on addition Glyceline as mentioned earlier.…”

Deep Eutectic Solvents are promising greener and cheaper alternatives to ionic liquids. The applications involving these solvents depend largely on their physical and chemical properties. However, a DES may possess both desirable and undesirable properties for a certain application. In such situations, mixing two DESs, each possessing a unique set of properties, may yield one with a more suitable set of physical and chemical properties for the same application. In this work, the variation in the physical properties of Reline upon addition of Glyceline was investigated. While a positive deviation of excess molar volume was observed, a negative deviation of viscosity was recorded with the increase in Glyceline mol% indicating a disruption of the ordered structure of Reline. The highest deviation in both cases was observed at 30 mol% Glyceline. The physical properties measured were density, viscosity, pH, RI and conductivity. The Glyceline molar percentage studied was 0 to 100 mol% while temperature was varied within the range of 20 o C to 80 o C.

Densities, U , at 298.15 K and atmospheric pressure have been measured over the entire composition range for the ternary systems (2-methyl, 2-chloro propane or 1-chlorobutane) + n-heptane + 2-pentanone and for five corresponding binary systems. Excess molar volumes, V E , were evaluated for the binary and ternary systems. The V E results were correlated and fitted using the Redlich-Kister equation for the binary mixtures and the NagataTamura equation for the ternary mixtures, as a function of mole fraction. Several predictive empirical relations were applied to predict the excess volumes of ternary mixtures from the binary mixing data and analyzed to gain insight about liquid mixture interactions. The excess molar volumes for the two ternary systems are positive over the entire range of composition for three fixed composition f m 1 2

“…This article is a continuation of our earlier work related to the study of thermodynamic and transport properties of binary mixtures [1][2][3][4][5]. In recent years, measurements of transport properties have been adequately employed in understanding the nature of molecular systems and physicochemical behavior in liquid mixtures.…”

Densities, Excess Molar Volumes, Viscosities, and Refractive Indices of Binary Mixtures of n-Butyl Acetate with 1-Chloroalkanes (C4–C8) at 298.15 K

Densities, viscosities, and refractive indices of binary mixtures of n-butyl acetate (1) + 1-chlorobutane (2), +1-chloropentane (2), +1-chlorohexane (2), +1-chloroheptane (2), and +1-chlorooctane (2) were measured at 298.15 K for the liquid region and at ambient pressure for the whole composition range. The excess molar volumes V E were calculated from experimental densities. McAllister's threebody interaction, and Hind and Grunberg-Nissan models are used for correlating the viscosity of binary mixtures. The experimental data of binaries are analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
