Popis: Ethylene glycol is an organic solvent used in extractive distillation to separate water–ethanol mixtures. An appropriate process description requires accurate physical property data. In this paper, experimental liquid densities and dynamic viscosities of pure ethylene glycol as well as the ternary system water–ethanol–ethylene glycol are presented over a wide temperature range (298.15 K to 328.15 K) at atmospheric pressure. A quadratic mixing rule was used to correlate the ternary liquid densities. The Eyring–Patel–Teja model with two Margules-type mixing rules for polar and aqueous systems is used to correlate the dynamic viscosity data over the measured ternary compositions and temperatures. An excellent agreement with experimental data is obtained. Additionally, the predictive ASOG-VISCO model demonstrated a good representation of the experimental data.
