Thermophysical study on the mixing properties of mixtures comprising 2-(2-methoxyethoxy)ethanol, butan-1-ol, butan-2-ol, and propan-1-ol

Abstract

Excess enthalpy (HE), dynamic and kinematic viscosities (η, υ), density (ρ), and refractive index (nD) of mixtures comprising 2-(2-methoxyethoxy)ethanol, butan-1-ol, butan-2-ol, and propan-1-ol are presented at p = 0.1 MPa and at T = 298.15 and 313.15 K. Deviations in refractive index (ΔnD) is generated from experimental data of refractive index. Experimental data of ρ for all binary mixtures are predicted using the PC-SAFT (Perturbed Chain-Statistical Associating Fluid) EoS. Furthermore, HE and ΔnD are adjusted using the Redlich–Kister equation. However, the correlation of measured data of HE is performed by using the UNIQUAC and NRTL models.
