High Pressure Phase Behavior of Methyl Acetate and Ethyl Acetate in the Supercritical Carbon Dioxide
Pressure-composition isotherms was obtained for the CO2-Methyl acetate and CO2-Ethyl acetate system at 40, 60, 80, 100, and 120 ℃, and the pressure a range of 15 ~ 119 bar. The solubilities measurement for CO2-Methyl acetate and CO2-Ethyl acetate increased with temperature at constant pressure. The CO2-Methyl acetate and CO2-Ethyl acetate systems exhibit type-I phase behavior with a continuous mixture critical. The experimental results obtained in this study are modeled using the Peng-Robinson equation of state. A good fit of the data are obtained with Peng-Robinson equation of state using two adjustable mixture parameter.
