TL;DR: In this paper, the Soave and Peng-Robinson equations of state were used to calculate the solubilities of several organic solids in four supercritical fluids, and three excess Gibbs free energy models were used in the mixing rules: NRTL, UNiQUAC and UNIFAC.
Abstract: Solubilities of several organic solids in four supercritical fluids are calculated with Soave and Peng-Robinson equations of state, incorporating excess Gibbs free energy into the mixing rules, with Heidemann-Kokal, Wong-Sandler and MHV2 procedures. Three excess Gibbs free energy models are used in the mixing rules: NRTL, UNiQUAC and UNIFAC. Furthermore, a comparison between these mixing rules and conventional two-binary-parameter form and modification of the excluded volume parameter in the MHV2 procedure is also presented. The best result were obtained with NRTL model and the Wong-Sandler mixing rule.

TL;DR: In this paper, it was shown that if one component obeys Henry's law, the other two components follow the two component Gibbs-Duhem equation, then there is no thermodynamic requirement of ideality.

TL;DR: In this paper, a new approach to chemical equilibrium is proposed to narrow the gap between introductory teaching and texts that deal with irreversible processes, in order to bridge the gap of introductory and non-introductory teaching.
