Density, isothermal compressibility, isobaric thermal expansion, and related excess properties of mixtures of 2-(2-ethoxyethoxy)ethanol+2-propanol at temperatures from 293.15 K to 353.15 K and pressures up to 70 MPa: Measurements, correlation, and PC-SAFT modeling

High-temperature and high-pressure density data for the binary mixtures x 2-(2-ethoxyethoxy)ethanol + (1-x) 2propanol are presented in this work, covering temperatures from 293.15 to 353.15 K and at pressures from 0.1 to 70 MPa. The experimental density data were generated using a vibrating tube densimeter with an uncertainty of 0.5 kg/m3. Experimental density data was fitted by using the Tait-like equation, yielding low standard deviations. Derivative properties such as excess molar volumes, isothermal compressibilities, excess isothermal compressibilities, and isobaric thermal expansions were calculated from the obtained density data. Additionally, the experimental measurements were modeled using PC-SAFT equation of state. The intermolecular interactions, as reflected in the derivative properties for each binary mixture, are thoroughly discussed.
