Abstract

In this study, we reported data of phase equilibria of the ternary {CO2 (1) + acetone (2) + pluronic F-127 (3)} system using the static synthetic method with a visual cell at temperatures ranging from 303 to 323 K, pressures near to 10 MPa, two concentrations of pluronic F-127 in acetone (0.01 g.cm(-3) and 0.02 g.cm(-3)), and molar fractions varying between 0.3 to 0.9. The thermodynamic modeling using the perturbed-chain statistical associating fluid theory equation of state (PC-SAFT EoS) was capable of describing the behavior of the experimental data (liquid-vapor transitions bubble points) satisfactorily.
