Title: High pressure phase behavior and modeling of CO2–propyl acrylate and CO2–propyl methacrylate systems
Abstract: Abstract High pressure phase behavior are obtained for CO 2 –propyl acrylate system at 40, 60, 80, 100 and 120 °C and pressure up to 161 bar and for CO 2 –propyl methacrylate systems at 40, 60, 80, 100 and 120 °C and pressure up to 166 bar. The solubility of propyl acrylate and propyl methacrylate for the CO 2 –propyl acrylate and CO 2 –propyl methacrylate systems increases as the temperature increases at constant pressure. The CO 2 –propyl acrylate and CO 2 –propyl methacrylate systems have continuous critical mixture curves that exhibit maximums in pressure at temperatures between the critical temperatures of CO 2 and propyl acrylate or propyl methacrylate. The CO 2 –propyl acrylate and CO 2 –propyl methacrylate systems exhibit type-I phase behavior with a continuous mixture critical curve. The experimental results for CO 2 –propyl acrylate and CO 2 –propyl methacrylate systems are modeled using both the statistical associating fluid theory (SAFT) and Peng–Robinson equations of state. A good fit of the data are obtained with SAFT using two adjustable parameters for CO 2 –propyl acrylate and CO 2 –propyl methacrylate systems and Peng–Robinson equation using one and two adjustable parameter for CO 2 –propyl acrylate and CO 2 –propyl methacrylate system.
