“…The pure parameters for the PC-SAFT model are typically determined from experimental data. In this study, data for alcohols and 1,3-dioxolane were obtained from previous research – , as they are indicated in Table . To improve the precision of the forecasts for the binary mixtures, the interaction parameter k ij was determined by the implementation of the subsequent equation. ε i j = ε i ε j ( 1 − k i j ) …”

“…Both 1,3-dioxolane and the alcohols had a mass fraction purity of greater than 99.5%, as shown in Table . Experimental measurements of density and viscosity for pure 1,3-dioxolane were performed in this study, – while data for the 1-alkanol were obtained from our previous work. – A comparison of the density and viscosity values for 1,3-dioxolane obtained in this study with those reported in the scientific literature is given in Table .…”

“…A fundamental aspect of this methodology is the establishment of a correlation between the Helmholtz energy resulting from molecular bonding and the density of the monomers, which is related to a function characterizing the intensity of such bonding. Recent research in our group has demonstrated the high reliability and consistency of the PC-SAFT theory when applied to complex pure fluids and their mixtures. – The present study focuses on the investigation of the experimental densities and viscosities of mixtures composed of 1,3-dioxolane and 1-alkanol compounds. Using the PC-SAFT approach in conjunction with the free volume theory, correlations are established between the data obtained.…”

The current study presents the viscosity and density (both experimentally determined and modeled) of five binary mixtures composed of 1,3-dioxolane and 1-alkanol compounds, namely, 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, and 1-decanol, in the range of 293.15−323.15 K. In addition, the effect of temperature and alkyl chain length of the alkanol on the excess molar volume and viscosity deviation of these mixtures has been thoroughly investigated and discussed. The results obtained are interpreted in terms of the structural changes that occur during mixing. Two approaches have been used to model the behavior of binary mixtures: the perturbed chain statistical associating fluid theory and free volume theory. Notably, satisfactory agreement between the experimental and calculated data derived from these models was observed. The average absolute deviations for the 1,3dioxolane + 1-alkanol mixtures predicted by the PC-SAFT model were approximately 1.13, 1.06, 1.03, 1.08, and 1.11%, respectively. Moreover, the deviations between the experimental viscosities and their correlated values, as determined by the free volume theory, were consistently less than 3% for all binary mixtures studied.

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.
