Experimental data of vapor-liquid equilibria (VLE) are reported for the binary systems: ethanol (1) + water (2) at 100, 1500, and 2000 kPa. The data were verified for thermodynamic consistency by using different low- and high-pressure tests. The following minimum azeotropes were found for the binary systems: x(1,az) = y(1,az) = 0.899 and T = 351.39 K at 100 kPa, x(1,)(az) = y(1,az) = 0.857 and T = 440.70 K at 1500 kPa, and x(1,)(az) = Y-1(,)az = 0.850 and T = 453.83 K at 2000 kPa. The quality of the azeotropic data obtained was established by considering the trend of the bibliographic azeotropic data. The phase behavior was modeled using the Peng-Robinson equation of state (EOS) with several mixing rules and the perturbed-chain statistical associating fluid theory. The experimental data were satisfactorily correlated and a qualitative agreement with these predictive models was observed.
