ABSTRACT

High-pressure phase behavior is obtained for CO2 (1) + benzyl acrylate (2) and CO2 (1) + benzyl methacrylate (2) systems at (313.2, 333.2, 353.2, 373.2, and 393.2) K and pressures up to 24.43 MPa. The solubility of monomers for the CO2 (1) + benzyl acrylate (2) and CO2 (1) + benzyl methacrylate (2) systems increases as the temperature increases at constant pressure. The CO2 (1) + benzyl acrylate (2) and CO2 (1) + benzyl methacrylate (2) systems exhibit type-I phase behavior. The experimental results for CO2 (1) + benzyl acrylate (2) and CO2 (1) + benzyl methacrylate (2) systems are correlated with the Peng Robinson equation of state using a van der Waals one-fluid mixing rule including two adjustable parameters. Critical constants (Pc, Tc, and u) are predicted with the Joback method and the Lee Kesler method.
