Phase equilibrium measurements, correlations and predictions are presented for the binary systems (R,S)-1-phenylethanol/CO2 and vinyl acetate/CO2 and for the ternary system vinyl acetate/(R,S)-1-phenylethanol/CO2. Experiments for the ternary system were performed in the temperature range of 323-343 K and in the pressure range of 7-12 MPa, using a high pressure phase equilibrium apparatus with a high pressure visual variable volume cell. Phase compositions were determined by taking samples of each phase and analysing them by gas chromatography. Equilibrium data were correlated with the Peng-Robinson equation of state combined with the Mathias-Klotz-Prausnitz mixing rule. A good correlation of both phases behaviour was obtained with an average absolute deviation (AAD) of 6.80%. Predictions for the binary sub-systems and for the ternary system were performed using the Peng-Robinson and the Soave-Redlich-Kwong equation of state, with the predictive mixing rule MHV1.
