“…According to Table S3, we can conclude that low statistical deviations are obtained when three parameters are used in the modeling of excess molar volume and deviation in viscosity, showing the correct modeling of the experimental data of V E and Δη using the Redlich–Kister polynomial. From Table S3, we can see that the excess molar volumes values are negative; these values imply that the attractive forces of the p -methyl acetophenone + alcohol are strong, e.g., induced dipole–dipole forces between p -methyl acetophenone and alcohol ,, and the contraction effect that occurs in the mixtures, i.e., the volume of the mixture is less than the sum of the volumes of the pure liquids.…”

“…Ketones, e.g., p -methylacetophenone, are used as solvents, polymer precursors, and in the preparation of many pharmaceuticals . On the other hand, alkanols are of interest in their own right and serve as a simple example of biologically and industrially important amphiphilic materials . The qualitative and quantitative analysis of thermodynamic properties, is expected to provide useful information for efficient design of processes.…”

The aim of this work is to investigate experimentally and theoretically thermophysical properties (density and viscosity) and derived properties (excess molar volume and viscosity deviation) of pmethylacetophenone + alkanols (C5 to C9) in the range of 293.15 to 323.15 K and a pressure of 0.1 MPa. The properties studied were density, viscosity, excess molar volume, and deviation in viscosity. To model the density of the liquid mixtures, we used the perturbed chain-statistical associating fluid theory equation of state (PC-SAFT EoS) and the volume translated Peng-Robinson-Stryjek-Vera equation of state (VTPRSV EoS). Using a correlation approach an overall deviation of 0.34% and 0.28% was obtained, respectively, while good predictive results were obtained (0.44% using PC-SAFT EoS and 0.46% using VTPRSV EoS). Also, we use two correlations without fitted parameters (Kendall-Munroe correlation and Nguyenhuynh correlation) to model the experimental viscosity and obtained an overall deviation of 5.07% and 3.07%. In addition, the Redlich−Kister correlation (with three fitted parameters) was able to correctly correlate the excess molar volume and the deviation in viscosity for all mixtures. Finally, the results obtained from the work have been discussed in terms of the nature of molecular interactions between the components of the p-methylacetophenone + alkanol mixture.

Density and absolute viscosity were measured for four binary mixtures composed by ethylene glycol diethyl ether and 1-alkanol (1-propanol to 1-hexanol). The measurements were carried out at 0.1 MPa and at four temperatures between 293.15 and 323.15 K. The density for the pure fluids and mixtures was correctly modeled with a perturbed chain-statistical associating fluid theory equation of state (PC-SAFT EoS). On the other hand, free volume theory combined with the equation of state was able to correctly model the absolute viscosity for all mixtures. The Redlich−Kister model was successfully applied in the correlation of derived properties as deviation in viscosity and excess volume. Also, the molecular interactions were studied from PC-SAFT EoS and the results of the excess volume.

Zinc (II) chloride based deep eutectic solvent (DES) were formed by mixing zinc (II) chloride with phosphoric acid. Fourier‐transform infrared spectroscopy was used to identify any possible shifts when the two compounds were assorted, and differential scanning calorimetry (SDT Q600 V20.9 Build 2D) was utilized to evaluate the formation of deep eutectic solvent. Densities, , and speed of sound, u, of [ZnCl2][phosphoric acid] 1:2.5 with methanol, ethanol, or propanol have been measured at T = (293.15, 303.15, 308.15, and 313.15) K and at atmospheric pressure. Excess molar volumes (), isentropic compressibilities (), deviation in isentropic compressibility (), and intermolecular free length () were calculated from the densities, and speed of sound, respectively. To fit the excess molar volumes and deviation in isentropic compressibilities, the Redlich–Kister smoothing polynomial was used. Also, we have used perturbed chain statistical associating fluid theory equation of state (PC‐SAFT EoS) for modeling the densities of the binary mixtures, and Schaaff's collision factor theory (SCFT) and Nomoto's relation (NR) were used for modeling the speed of sounds for the binary mixtures.
