000094471 5203_ $$aThis contribution reports densities together with the corresponding excess molar volumes, and excess molar enthalpies of the binary mixtures formed by ethyl isobutyrate and n-alkanols (from methanol to 1-butanol) at two temperatures (303.15 and 323.15) K and at atmospheric pressure (p= 0.1 MPa). These excess properties were correlated with composition using the Redlich-Kister equation. Excess molar volumes and enthalpies are positive, except the excess molar volumes for the mixture ethyl isobutyrate and methanol. Furthermore, the vapor-liquid equilibrium data for these mixtures at different experimental conditions have been also presented. Both the isothermal VLE at two temperatures (303.15 and 323.15) K and isobaric VLE at two pressures (40.000 and 101.325) kPa were measured. Some of the systems exhibit azeotropic points. The VLE data were found thermodynamically consistent. From experimental data the activity coefficients along with excess Gibbs function (isothermal) and reduced excess Gibbs functions (isobaric) were obtained and correlated with composition using the Wilson equation. These excess Gibbs function and reduced excess Gibbs functions were found positive. Finally, we have used our experimental VLE data to check the reliability of modified UNIFAC predictions.
