High pressure phase behavior of the CO2 + 2-ethoxyethyl methacrylate (2-EEMA) and CO2 + 2,3- epoxypropyl methacrylate (2,3-EPMA) systems has been investigated in static method at five temperatures of 313.2, 333.2, 353.2, 373.2 and 393.2 K and pressures up to 21.3 MPa. Both CO2 + 2-EEMA and CO2 + 2,3-EPMA systems have continuous critical mixture (locus) curves that exhibit maximums in pressure temperature space between the critical temperatures of CO2 and 2-EEMA or 2,3-EPMA. The solubility of 2-EEMA and 2,3-EPMA for the CO2 + 2-EEMA and CO2 + 2,3-EPMA systems increases as the temperature increases at fixed pressure. The CO2 + 2-EEMA and CO2 + 2,3-EPMA systems exhibit type-I phase behavior. The experimental results for the CO2 + 2-EEMA and CO2 + 2,3-EPMA systems are correlated with Peng Robinson equation of state using a mixing rule including two adjustable parameters. The critical properties of 2-EEMA and 2,3-EPMA are predicted with Joback Lyderson and Lee Kesler method.
