The density of binary system 2 eleven different compositions, at nine isotherms at the temperatures ranging from 293.15 K and eight isobars up to 30 MPa with a vibrating were correlated with Tait-type equation and isobaric thermal expansion coefficients, isothermal compressibility, were calculated. The study is completed with modeling in terms of the simplified perturbed-chain statistical The pure compound’s new parameters of the sPC fitting the equation to experimental saturated vapor pressure and liquid density data. In this work, by simultaneously minimizing the total objective function of temperature, pressure and density, new correlations were developed to estimate the sPC ethers including, 2-butoxyethanol, and 2 %AAD of 0.10 in average. A new association scheme for sPC for more accurate predictions of 2 In this case, for the mixture, the interaction parameter density data with an overall AAD the evaluation of derivative properties such as isobaric thermal expansion coefficients, isothermal compressibility, , isobaric heat capacities, indicated that the correlations/predictions proposed in this work can be used to correlate /predict the densities and the derivative properties of the examined systems as functions of temperature, pressure and composition. The abstract should be a single page wh and scope of the article.
