The experiments were carried out using a circulation-type equilibrium apparatus with the measurement of temperature, pressure, and the compositions of the liquid and vapor phases. The experimental data were correlated with the Camahan-Starling-De Santis (CSD) equation of state. Calculated results showed good agreement with experimental data for both binary systems. It was found that these two systems have very strong positive azeotrope for all the temperature ranges studied here. (c) 2006 Elsevier B.V. All rights reserved.
