In this work the phase behavior of the binary system (ethyl lactate + CO2) was studied in the pressure range 0.4–17 MPa and at temperatures of 313.2, 333.2, 353.2, 373.2 and 393.2 K. Experiments were performed using the static synthetic method in a high pressure variable–volume view cell. Equilibrium data were correlated with the Peng–Robinson equation of state combined with the Mathias–Klotz–Prausnitz mixing rule. Additionally, density-based correlations, namely Chrastil's and Fornari's equations were used in order to correlate solubilities in both liquid and vapor phases.
