Densities and heats of mixing for the ternary system 2-butanol + 1,3-dioxolane + cyclohexane have been measured at 298.15 and 313.15 K. Excess molar volumes and excess molar enthalpies have been calculated from experimental data and fitted by the Redlich–Kister equation. The ERAS model has been used to calculate excess molar properties of the ternary mixture from parameters obtained from the constituent binary mixtures.Key words: excess properties, ERAS model.

Data Points

In this paper, the Prigogine?Flory?Patterson (PFP) theoretical model and the extended real association solution (ERAS) model for the prediction of the excess molar volumes of 17 binary sets of alcohols (methanol, ethanol, propan-1-ol, butan-1-ol, butan-2-ol and pentan-1-ol) with benzene, chlorobenzene, acetonitrile, hexan-1-amine and n-heptane were tested at 298.15 K and atmospheric pressure. The binary sets contained 333 experimental data points for 11 different compounds. The ERAS model demonstrated better correlative characteristics for binary mixtures comparing to PFP model. The ERAS model is successfully applied on all binary systems except ethanol + benzene and propan-1-ol + benzene. PFP model gave less satisfactory results for all systems except butan-1-ol + hexan-1-amine, for which obtained results were acceptable.
