Resumen: The isobaric vapor–liquid equilibrium for the binary mixtures of 2–Butanol + n–Heptane and 2–Butanol + 2,2,4–Trimethylpentane at 1.5 MPa and 2.0 MPa were obtained experimentally using a stainless steel ebulliometer. The experimental data have been verified thermodynamically. The data were fitted by using a polinomial zetas equation to perform the data reduction. The ϕ–ϕ approach was applied using the Perturbed Chain–Statistical Associating Fluid Theory and the Peng–Robinson–Stryjek–Vera equation of state using both quadratic and Wong–Sandler mixing rules. It has been verified that composition of the azeotropic points in both mixtures is modified by increasing the pressure. The trend of the azeotropic data was studied using bibliographic data from each mixture.
