High-pressure phase equilibria of the binary systems carvone–carbon dioxide and limonene–carbon dioxide at 30, 40 and 50°C

Phase equilibrium data for the systems carvone–CO2 and limonene–CO2 were determined at 30, 40 and 50°C using an equilibrium cell with circulating gas phase. The experimental data could be successfully correlated by using the Peng–Robinson equation of state using different sets of mixing rules.
