| Abstract: | Based on the solubilities of pimelic acid in ionic liquids EMIM]HSO4], PMIM]Br, i-PMIM]HSO4], BMIM]Br, and BMIM]HSO4], dissolution enthalpy and dissolution entropy at different temperatures have been calculated. The experimental data of solubilities are correlated with the modified Apelblat equation. The thermodynamic properties of pimelic acid in ionic liquids were discussed. The solubilities correlated by the model are in good agreement with experimental data. |
