ABSTRACT

The solubility of different conventional salts in several room-temperature ionic liquids containing ammonium, phosphonium or imidazolium cations combined with acetate, sulfate, sulfonate, thiocyanate, chloride, tetracyano-borate, tris(pentafluoroethyl)trifluoro-phosphate, L-lactate, bis(trifluoromethylsulfonyl) imide or trifluoromethylsulfonate anions were screened using a visual detection method. The most promising mixtures were then re-measured using an ATR-FTIR (Attenuated Total Reflection Fourier Transform Infra Red) spectroscopy technique in order to accurately and quantitatively determine the corresponding solubility at 298.15 K.
