ABSTRACT
Vapor liquid phase equilibrium data are obtained for mixtures of CO2 + isopropyl acrylate and CO2 + isopropyl methacrylate systems at 313.2, 333.2, 353.2, 373.2, and 393.2K and pressures up to 14.20MPa. The solubility of CO2 for the CO2 + isopropyl acrylate and CO2 + isopropyl methacrylate systems decreases as the temperature increases at constant pressure. The CO2 + isopropyl acrylate and CO2 + isopropyl methacrylate systems exhibits type-I phase behavior, characterized by a continuous critical line from pure CO2 to the second component with a maximum in pressure. The experimental results for the CO2 + isopropyl acrylate and CO2 + isopropyl methacrylate systems were correlated with Peng Robinson equation of state using a van derWaals one-fluid mixing rule. The correlation results have shown a good agreement with the Peng Robinson equation using two adjustable interaction parameters for the systems.
