Measurement and modeling of isobaric vapor - Liquid equilibrium and isothermal interfacial tensions of ethanol + hexane + 2,5 - Dimethylfuran mixture

The experimental isobaric VLE and isothermal IFT data of the ternary mixture were accurately characterized by applying the linear square gradient theory to the Peng-Robinson Stryjek-Vera equation of state (EoS) appropriately extended to mixtures by means of the modified Huron-Vidal mixing rule. This model allows directly transferring the experimental excess Gibbs energy function to the EoS model for equilibrium and interfacial tension calculation purposes. This theoretical framework shows that both experimental VLE and IFT data can be accurately predicted by using binary contributions and provide a route to interpolate values phase equilibrium and interfacial tension.
