Název v původním jazyce

Solubility of beta-Carotene in Supercritical CO2 and the Effect of Entrainers.

Popis výsledku v původním jazyce

Solubilities of trans- -carotene in supercritical CO2, both pure and modified, were measured at temperatures 313.2, 323.2 and 333.2 K and pressure up to 28 MPa using a one-pass flow apparatus. The solubility data measured in pure CO2 were correlated by the density-based equation proposed by Chrastil and modelled using the Soave-Redlich-Kwong cubic equation of state. Most of the literature data were in good agreement with ours results; smaller discrepancies were ascribed mostly to -carotene degradation.While ethanol entrainer increased the solubility of -carotene in supercritical CO2 by one order of magnitude, vegetable oil was less efficient. In both cases, the increase in solubility was proportional to square root of entrainer concentration.
