Essential Oils from Seeds: Solubility of Limonene in Supercritical CO2 and How It Is Affected by Fatty Oil.

Popis výsledku v původním jazyce

Fatty oil influence on the solubility of limonene in CO2 was investigated under pressures 8-12 MPa at 313.2 K, a temperature typically applied in supercritical fluid extraction of essential oils. Solubility in CO2 was measured using the dynamic method both for limonene and for the mixture of limonene and blackcurrant seed oil. In the whole range of pressures applied, the concentration of fatty oil in the vapour phase is negligible in comparison with the concentration of limonene. Limonene is distributedbetween the liquid phase rich in fatty oil and the vapour phase rich in CO2, and its equilibrium concentration in the latter decreases with the diminishing limonene-to-oil ratio in the saturator. There is a steep increase of the limonene partition coefficient with pressure between 8 and 10 MPa, near the critical pressure of the binary mixture of limonene and CO2. The observed behaviour of the three-component system was confirmed and explained by thermodynamic modelling. The thermodynami
