Solubility measurement, modeling and mixing

Henry’s law constants and the mixing thermodynamic properties for the two mixtures were determined. Abstract 3,3,3-Trifluoropropene (R1243zf) and isobutane (R600a) are considered as prominent environmentally-friendly refrigerants, and acetate-based ionic liquids are potential absorbents used in absorption refrigeration cycles.

Fluid-mineral equilibria and thermodynamic mixing

2013-11-7  The paper presents a review of an experimental method to quantitatively constrain thermodynamic mixing properties of fluid systems at high temperature T and pressure P. The method is based on bracketing equilibrium parameters of simple fluid-mineral reactions. Experimental data obtained with this technique for the H2O-CO2, H2O-N2, and H2O-H2 binary systems were utilized to calculate

Is mixing a thermodynamic process?: American Journal of

1998-6-4  Mixing processes exist with positive entropy change and negative free energy change. However, the idea that the irreversibility of the mixing processes is responsible for the so‐called free energy and entropy of mixing is faulty. The mixing, as well as the demixing processes may be associated with either reversible or irreversible phenomena, depending on the particular conditions.
