Abstract: Density (ρ), speed of sound (u), viscosity (η), and refractive index (nD) were measured for pure acetonitrile, trichloroethene, and tetrachloroethene, as well as their binary mixtures at temperatures T = (293.15, 298.15, 303.15) K and at ambient pressure (81.5 kPa). From the experimental data, excess molar volume (VmE), thermal expansion coefficients (α), deviations in isentropic compressibility (△ks), viscosity (Δη), and refractive index (ΔnD) were calculated. These values were then correlated using the Redlich-Kister polynomial equation, with fitting coefficients and standard deviations determined. Additionally, the Prigogine-Flory-Patterson (PFP) theory and the Extended Real Associated Solution (ERAS) model were employed to correlate the excess molar volume, while the Perturbed Chain Statistical Associating Fluid Theory (PC-SAFT) was used to predict the density of mixtures.

Key words: Thermodynamic properties, Mixture, Viscosity, PFP theory, ERAS model, PC-SAFT model
