Abstract:

The dataset supports a thermodynamic analysis of multicomponent drop dissolution, for both growing and dissolving drops, with and without a non-zero initial concentration of the drop constituents in the host liquid. In some cases the results, which have important implications e.g. for solvent extraction processes in the chemical and environmental remediation industries, show major deviations from the predictions of approximations in current use including simple extensions of the Epstein-Plesset theory. We used the UNiversal QUAsiChemical (UNIQUAC) model to describe phase equilibria. UNIQUAC inputs and thermodynamic equilibrium data are provided for 3 systems: ethyl acetate, butyl acetate, and water; acrylonitrile, propionitrile and water; and toluene, heptane, and perflurocyclic oxide. Data include results for a phase equilibrium model and simplified linear model for the three systems.
