Near-criticality in dilute binary mixtures: Distribution of azulene between coexisting liquid and vapor carbon dioxide
The equilibrium distribution of dilute solutes between vapor and liquid coexisting phases of near critical solvents was discussed. It exhibits a dependence on the solvent's liquid density, which extends over a wide temperature range. To quantitatively test the extension of the equilibrium distr...

| Sumario: | The equilibrium distribution of dilute solutes between vapor and liquid coexisting phases of near critical solvents was discussed. It exhibits a dependence on the solvent's liquid density, which extends over a wide temperature range. To quantitatively test the extension of the equilibrium distribution, a high pressure apparatus with a sampling manifold was used to measure the equilibrium concentrations of azulene in coexisting liquid and vapor carbon dioxide contained in a high pressure sapphire cell. The density and composition of the two phases under equilibrium were determined between 283 and 301 K. |
