ABSTRACT
The excess volume of binary mixtures and the isobaric vapor-liquid equilibrium (VLE) data at high pressure have been determined. The VLE for Methyl Acetate + n-Heptane or 2,2,4-Trimethylpentane and Ethyl Acetate + n-Heptane or 2,2,4-Trimethylpentane at several pressures were obtained experimentally using a stainless steel ebulliometer. The experimental data at 0.1 MPa were verified by using the point-to-point test. The high pressure data were verified by employing the - approximation. The equations of state (EOS) of Peng-Robinson-Stryjek-Vera, with both quadratic or Wong-Sandler mixing rules, and the PC-SAFT were applied for modelling purposes. It has been verified that the azeotropic point in the binary mixtures of this work was eliminated by increasing the pressure.
