Viscosity and density data for the ternary system water(1)–ethanol(2)–ethylene glycol(3) between 298.15 K and 328.15 K
چکیده انگلیسی

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.


► We measure density and dynamic viscosity of pure ethylene glycol.
► We measure ternary densities with water and ethanol.
► We measure ternary dynamic viscosities with water and ethanol.
► The Eyring–Patel–Teja model correlate well ternary viscosities.
► We predict ternary dynamic viscosities with the ASOG-VISCO model.
