A static method was used for measuring vapor pressures of (1-propanol + 1,8-cineole). Measurements were carried out at 10 temperatures between 278.15 K and 323.15 K and over the whole composition range. Experimentally determined vapor pressure data were reduced applying Barker s method and fitted using the Wilson equation, so activity coefficients and excess molar Gibbs energies were obtained. Vapor liquid equilibrium (VLE) correlation and description of the volumetric behavior of the mixture were obtained by using three equations of state (EOS). Volume translation (VT) according to Peneloux was considered in two of them, modifications proposed by Mathias (PRM) and by Stryjek Vera (PRSV) to the Peng Robinson equation. The last model applied was the statistical associating fluid theory (SAFT), based on the theory of perturbations. This third model provides the best description of the volumetric behavior, although the Stryjek Vera modification is the one that provides the best description of the phase equilibrium.
