摘要：
The solubilities of potassium fluoride (KF) in tributyl phosphate, dimethyl sulfoxide, N,N-dimethylacetamide and 1,4-dioxane were determined, the experimental data were correlated with the modified Apelblat equation. The dissolution enthalpy and entropy had been calculated from the solubility data. The interactions between solute and solvent were discussed. The obtained data are basic for preparation of 2,3,4,5-tetrafluorobenzoic acid process.
