Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the temperature range from 288.15 to 323.15 K and at atmospheric pressure. The choice of mixtures was based on their potential for practical application. From experimental data, excess molar volume, viscosity deviation, excess molar Gibbs free energy of activation of viscous flow, deviation in refractive index, and deviation in isentropic compressibility are calculated, correlated with the Redlich–Kister equation and used for better understanding of molecular interactions between the mixture components. Also, partial molar volumes, excess partial molar volumes, and partial molar volumes at infinite dilutions were calculated to elucidate the nonideal behavior of the investigated mixtures. Since the mixtures were investigated both from the theoretical point of view and with the aspect for practical application, the modeling of two key properties, viscosity and excess molar volume, was performed with different models and approaches, and the results are compared with experimental values.

“…All these solvents were used without any additional treatment. The purity was ascertained by comparing the measured values of densities and viscosities of pure solvents with literature values [20][21][22][23][24][25][26] which shows reasonable agreement (Table 1). The binary mixtures of liquids of different compositions were prepared by mass using an analytical balance (METTLER PM 200) with an accuracy of ± 0.0001g.…”

In this study, densities and viscosities of binary mixtures formed by ethyl acetate with n-propanol and 2-propanol have been measured over the entire range of composition at 303.15, 308.15, 313.15, and 318.15 K. Excess molar volume (VE), excess viscosity (ηE), excess Gibb’s free energy of activation (ΔG*E) and Grunberg-Nissan interaction parameter (d12) have been evaluated from experimental density and viscosity data. The computed excess functions VE, ηE, and ΔG*E have been fitted to Redlich-Kister polynomial equation. The observed values of excess properties and interaction parameters for both the systems have been interpreted in terms of molecular interactions in the mixtures. Results show that for both mixtures, the chemical or specific interactions between ethyl acetate and alcohol molecules are absent, and dispersion type of forces are predominant.

In the present study, measurements of the experimental density (ρ), speed of sound (c), and refractive index (n D ) of binary liquid mixtures of ethyl lactate (EL) with 2-aminoethanol (2-AE), 2-chloroethanol (2-CE), and ethyl acetate (EA) have been carried out within the temperature range from 298.15 to 323.15 K with an interval of 5 K and at 0.1 MPa. Excess volume (V E ), isentropic compressibility (k s ), excess isentropic compressibility (k s E ), and excess refractive index (n D E ) for the above liquid mixtures were calculated from the experimental measurements and they were correlated with the Redlich−Kister equation. Also, we obtained good fitting results in the computation of the density with perturbed chain statistical associating fluid theory equation of state and predictive results in the computation of the refractive index and speed of sound with several mixing rules and Nomoto's relation, respectively. Further, we measured the Fouriertransform infrared (FT-IR) spectral data of pure liquids and their mixtures at different concentrations and simulated the molecular interactions using density functional theory (DFT) calculations for the 3 sets of binary systems with the ADF 2020.102 package at the GGA BP86-D3 level of theory with TZP. Apart from these, the type and nature of molecular interactions and structural effects were studied between the component molecules with the aid of excess thermodynamic properties, FT-IR measurements, and DFT calculations.
