Solubility in the supercritical state.

Solubility enhancement in supercritical solvents

The enhancement of solubility of a solid in a supercritical solvent is interpreted with emphasis placed on binary mixtures of the second class. The selection of supercritical solvent ; the choice of temperature and pressure for supercritical fluid extractions; the characteristics of solubility curves between and in the vicinities of the upper critical and the lower critical end points; the effe...

Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide

Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...

Solubility of Tridodecylamine in Supercritical Carbon Dioxide

Using a continuous flow apparatus, the solubility of tridodecylamine (TDA) in supercritical CO2 (scCO2), have been measured at temperatures of 308, 318, and 328 K in the pressure range of (8-40) MPa and a flow rate of 150 ± 10 mL min. At 308 and 318 K the solubility increases with pressure up to 15 MPa where it reaches a plateau. At 328 K the solubility increases with pressure up to 35 MPa and ...

Modeling solubility in supercritical fluids via the virial equation of state

We examine the utility of the virial equation of state (VEOS) for the prediction of the solubility of hexane in supercritical carbon dioxide. We computed virial coefficients up to fourth-order for this mixture at 353.15 K, using Mayer-sampling Monte Carlo applied to established molecular models for carbon dioxide and hexane. At this temperature, neither the thirdnor fourth-order VEOS indicate t...
