Abstract
The solubilities of potassium fluoride in different non-proton polar solvents had been determined using a dynamic method at temperature ranging from 300.87 to 367.37 K. The two parameters solubility equation was correlated with the experimental data. The dissolution enthalpy and dissolution entropy had been calculated from the solubility data. The interactions between solute and solvent were discussed. It provided the basic data for preparation of 2,3,4,5-tetrafluorobenzoic acid.
