The experiments were carried out with a circulation-type equilibrium apparatus with measurement of the temperature, pressure, and compositions of the liquid and vapor phases. The experimental data were correlated with the Peng-Robinson equation of state using the Wong-Sandler mixing rules. Results calculated with this equation showed good agreement with the experimental data. Azeotropic behavior has not been found in either of these mixtures.
