| Popis: | In this paper experimental equilibrium data of the system CO 2 – bergamot essential oil are reported at 323 K and 343 K, in the pressure range 7.8–13.1 MPa. Furthermore equilibrium data for the subsystem CO 2 – linalyl acetate at 323 K are reported in the pressure range 7.0–10.3 MPa. The equilibrium data are predicted by means of two thermodynamic models based on Peng – Robinson and PC-SAFT equations of state. In particular the bergamot essential oil is described as a mixture of four components: limonene, linalool, linalyl acetate and β-caryophyllene. In the models regression parameters are calculated from data of binary subsystems, CO 2 – limonene, CO 2 – linalool and CO 2 -β-caryophyllene, and CO 2 – linalyl acetate. Therefore both of the models are predictive with regard to the bergamot oil and show quite a good agreement (especially the Peng Robinson one) with respect to the experimental data. |
