Abstract

In this study, the solubility of sodium chloride in 16 imidazolium-, pyrrolidinium-, pyridinium-, and ammonium-based ionic liquids at different temperatures was measured. The solubility of sodium chloride was found to increase with temperature in all of the ionic liquids studied. Both cations and anions in the ionic liquid affected solubility, but anions had more of an effect than cations. The highest measured solubility of sodium chloride was 8.96 wt % at 125 C in 1-ethyl-3-methylimidazolium dimethyl phosphate. The nonrandom two-liquid model was used to calculate the solubility of sodium chloride in some ionic liquids. The experimental and calculated values were in good agreement in many cases.
