Abstract
The conventional thermodynamic deviation for ideal solid-liquid solubilities is modified by substituting the Flory-Huggins model for Raoult's law. A comparison of published data for eleven solides in glyceryl trioleate with the predictions of the conventional and modified equations shows that the significantly higher athermal solubilities from the modified equation are in much better agreement with the experimental data. This suggests that discrepancies between the data and the predictions of the conventional model for ideal systems result from the inappropriate use of Raoult's law for systems with significant solute-solvent size disparity rather than from specific interactions.
