ABSTRACT

Densities measured at pressures from (20 to 40) MPa and the temperatures (283.15, 298.15, 313.15, and 328.15) K and isobaric (vapor + liquid) equilibrium (VLE) at pressures of (33.33, 66.66, and 101.33) kPa are reported for the mixture {1,8-cineole(1,3,3-trimethyl-2-oxabicycle[2,2,2]octane) + propan-1-ol} in the whole composition range. Excess molar volumes, isobaric thermal expansions, and isothermal compressibilities were calculated from the density data. VLE data were correlated by means of three activity coefficient models [Wilson, nonrandom two-liquid (NRTL), and universal quasichemical activity coefficient (UNIQUAC)], and their thermodynamic consistency was determined. Four equations of state (EOS), namely, the Peng-Robinson, the Patel-Teja, statistical associating fluid theory (SAFT), and perturbed-chain statistical associating fluid theory (PC-SAFT), were used first to predict (interaction parameters, kij, equal to zero) both the density and the VLE behavior of the system and second to correlate the VLE by adjustment of the interaction parameters for each EOS.
