High Pressure Phase Behavior for CO2 + Benzyl Acrylate and CO2 + Benzyl Methacrylate Systems

摘要：

High pressure phase behavior are obtained for CO2 + benzyl acrylate systems at 40～120 ℃ and pressures up to 243 bar and for CO2 + benzyl methacrylate systems at 40, 60, 80, 100 and 120 ℃ and pressures up to 244 bar. The solubility of monomers for the CO2 + benzyl acrylate and CO2 + benzyl methacrylate systems increase as the temperature increases at constant pressure. The CO2 + benzyl acrylate and CO2 + benzyl methacrylate systems exhibit type-I phase behavior. The experimental results for CO2 + benzyl acrylate and CO2 + benzyl methacrylate systems were correlated with Peng-Robinson equation of state using a van der Waals one-fluid mixing rule including two adjustable parameters. Critical constants (Pc, Tc and ω ) were predicted with Joback method and Lee-Kesler method.
