Phase equilibria data for the 1-phenylethanol−CO2 and 2-octanol−CO2 systems were measured at 303.15 K, 313.15 K, and 323.15 K and at pressures up to 145 bar. An equilibrium cell with circulating gas phase was used for the measurements. Data were correlated with the Peng−Robinson equation of state. Different methods were tested for calculating the binary interaction parameters k ij and l ij of the quadratic mixing rules.
