TLDR
In this paper, the solubility of carbon dioxide in organic solvents acetone and propionic acid has been measured with an analytical method, and the composition and the density of the liquid phase in the binary vapor−liquid equilibrium have been investigated at (313 and 333) K (for the system carbon dioxide + acetone) and at (298, 313, and 333), at pressures up the binary critical pressure.Abstract:
The solubility of carbon dioxide in organic solvents acetone and propionic acid has been measured with an analytical method. The composition and the density of the liquid phase in the binary vapor−liquid equilibrium have been investigated at (313 and 333) K (for the system carbon dioxide + acetone) and at (298, 313, and 333) K (for the system carbon dioxide + propionic acid) at pressures up the binary critical pressure. The experimental results for the phase equilibrium have been correlated with the Peng−Robinson EOS applying several mixing rules.read more

TL;DR: In this paper, a new equation based on Scott's two-liquid model and on an assumption of nonrandomness similar to that used by Wilson is derived, which gives an excellent representation of many types of liquid mixtures.

TL;DR: In this article, a new apparatus for the rapid determination of fluid phase equilibria up to 300 bar and 120°C was described, and the results, correlated with a modified Redlich-Kwong-Soave equation of state with mixing rules, are interpreted with respect to the extractability of acetone from diluted aqueous solutions using compressed CO 2 as the solvent.
