Abstract

Herein, we report the cloud point measurements of the CO2 + 2-hydroxyethyl methacrylate (HEMA) and CO2 + methyl methacrylate (MMA) systems. Experimental data were obtained at (313.15, 323.15, and 338.15) K and pressures up to (10.5 and 21.1) MPa, respectively. The Soave-Redlich-Kwong equation of state with the Mathias-Klotz-Prausnitz mixing rule was used to model experimental results, and a good correlation was achieved. Both systems were shown to be temperature dependent, with a solubility decrease with increasing temperature. Comparing the two studied systems, it was possible to notice that CO2 + HEMA experimental data were shifted to higher pressures than those observed for the CO2 + MMA system. This behavior suggests that CO2-HEMA interactions are weaker than those established between CO2 and MMA.
