“…Over the last three decades, significant progress has been witnessed in the theoretical understanding of liquid-liquid binary mixtures [1,2], keeping in view that the prediction of the few important properties like density, viscosity, and the excess properties, is related to their engineering performance. Studies on the theoretical modelling of thermodynamic and engineering properties have been carried out on alcohol-based binary/ternary mixtures like water and ethanol [3], 1,3,5-trimethyladamantane + 1,2,3,4-tetrahydronaphthalene + n-octanol and corresponding binary systems [4], n-hexane, ethanol, and cyclopentyl methyl ether [5], pentanol + ethyl cyclohexane + methyl myristate and corresponding binary systems [6] and ethylene glycol-based ternary mixture [7]. The knowledge of the thermodynamic and transport properties of alcohol-based binary mixtures can be used to develop theoretical models and for the design of new technologies.…”

This study reports the comparative deviations in experimental viscosity, density and ultrasonic velocity of two new ethanol-based binary liquid mixtures (ethanol + 1-hexanol and ethanol + 1-octanol) at 303.15 K by applying various theoretical models (Hind relation (ηH), Kendall and Monroe relation (ηK-M), Bingham relation (ηB), Arrhenius–Eyring relation (ηAE), Croenauer-Rothfus Kermore relation (ηCRK) and Gambrill relation (ηG)). Typically, the experimental densities are compared with theoretical methods like the Mchaweh–Nasrifar–Mashfeghian model (ρMNM), Hankinson and Thomson model (ρHT), Yamada and Gunn model (ρYG) and Reid et al. (ρR) model. Additionally, the experimental ultrasonic velocities are compared with various theoretical models like the Nomoto relation (UN), Van Dael and Vangeel relation (UIMR), Impedance relation (UIR), Rao’s specific velocity relation (UR) and Junjie relation (UJ). The average percentage of deviation (APD) is determined to identify the most suited model that can closely agree to the experimental values of the specified property (viscosity, density and ultrasonic velocity). From the APD values, it may be concluded that the ηK-M model is the most suitable theoretical method for estimating the viscosity for the ethanol + 1-hexanol system, and the Gambrill model is the suitable method for estimating viscosity for ethanol + 1-octanol liquid systems. Similarly, the model of Reid et al. and Jungie’s relation are the most suited theoretical models to predict the density and ultrasonic velocity of the binary liquid systems, respectively. Form the experimental data, various molecular interaction properties like adiabatic compressibility, intermolecular free length, free volume, internal pressure, and viscous relaxation time are analysed. The results of this study are expected to be useful in predicting the suitable molecular proportions that can be suited for industrial application (flavouring additive, insecticide, in the manufacture of antiseptics, perfumes for 1-hexanol based mixtures and flavouring, and as an antifoaming agent for 1-octanol based liquid mixtures).

The density of five 1-alcohols (1-hexanol, 1heptanol, 1-octanol, 1-nonanol, and 1-decanol) was measured using a vibrating-tube densimeter at pressures of up to 120 MPa for temperatures between 298.15 and 423.15 K. The relative expanded uncertainty of the experimental data is below 0.2%. The new results significantly extend the available literature data. The density of the five alcohols was modeled using four molecular-based equations of state (EOSs), namely PC-SAFT, SAFT-VR Mie, soft SAFT, and CPA. New component-specific EOS models were parametrized for all considered EOSs and substances using vapor−liquid equilibrium data from the literature and the density data from this work. The resulting EOS models describe the density with deviations of about 0.2−1.5%. For the thermal second-order derivative properties, the relative deviations were 10−50% for the isothermal compressibility and 5−35% for the thermal expansion coefficient. Also, the extrapolation behavior of the EOS models was assessed. Overall, the best results were obtained from the SAFT-VR Mie EOS.
