Thermophysical properties of binary liquid mixtures of oxygenated compounds: 2-Methoxyethanol plus alcohols at T=298.15 K and 313.15 K

Thermophysical properties as density, (rho), dynamic and kinematic viscosities, (eta, D), refractive index, (n(D)), and excess enthalpy, (H-E), are presented in this present work for binary mixtures containing 2-methoxyethanol, 1-butanol, 2-butanol, and 1-propanol at T = (298.15 and 313.15) K and at p = 0.1 MPa, over the whole range of composition. Derivative properties such as excess volume, (V-E), and deviations in refractive index, (Delta n(D)), were calculated from the measured data of density and refrac-tive index, respectively. The Perturbed Chain-Statistical Associating Fluid (PC-SAFT) Equation of State is used to correlate the experimental data density for the studied binary mixtures. Also, the Redlich-Kister equation is employed to fit the excess volumes, deviations in refractive index, and excess enthalpies. Besides, the NRTL and UNIQUAC models are applied to correlate the measured data of excess enthalpy, (H-E). Moreover, intermolecular interactions have been discussed for the studied binary mixtures.
