Abstract

The equilibrium solubilities of L-carvone and L-limonene in the binary (L-carvone-CO₂ and L-limonene-CO₂) and ternary (L-carvone-L-limonene-CO₂) systems were obtained at 39°C and 49°C and at pressures ranging from 6 to 10 MPa. The solubilities of these components increased with a pressure increase or a temperature decrease. The solubility of L-limonene was higher than that of L-carvone at the same temperature and pressure. The correlation of the solubilities using Chrastil equation revealed that the solubilities of both components were strongly dependent on the density of CO₂. In the ternary system simulating the actual spearmint oil composition, the solubility of L-carvone was similar but the solubility of L-limonene was lower as compared to their solubilities in the binary systems.
