Solvation thermodynamics of alkali and halide ions in ionic liquids through integral equations.

摘要: In this work, we study the solvation thermodynamics and other properties of small ions in two room-temperature ionic liquids, dimethyl imidazolium hexafluorophosphate [mmim] [pf6] chloride [mmim][cl] with reference interaction site model (RISM). The nature charge affects several aspects solvation, from electrostriction to mutual disposition cations around solute; nevertheless, long-range screening behavior liquid appears be insensitive both dimensions solute. ion is energy driven, as expected for solvent, displays a marked asymmetry between cation anion chemical potential. Such dependent, even qualitatively, on chosen solvent. Partial molar volumes solution are found follow ion-solvent interaction.
