ABSTRACT
Pressure-composition isotherms are obtained for the system CO2 + hexanal at (323.15, 353.15, and 383.15) K and pressures between (2.6 and 14.8) MPa. The phase equilibria measurements were carried out with an analytical method. The results were correlated by the Peng-Robinson (PR) equation of state using conventional mixing rules with two temperature-dependent interaction parameters.
