Densities of one acidic ionic liquid (IL) Quinolinum hexafluorophosphate ([HBpy][PF6]), and four neutral dicationic ionic liquids (ILs) based on quinoline and hexafluoro-phosphate and linked with poly(ethylene glycol) (PEG): ([PEG200-DIL][PF6]2, [PEG400-DIL][PF6]2, [PEG800-DIL][PF6]2 and [PEG1000-DIL][PF6]2) were determined. In addition, the solubilities of six ILs in six lower alcohols, water, acetonitrile and diethyl ether were measured at 288.15 K; and the hydroscopicity of above five ILs were measured at the temperature of 298.15 K and relative humidity of 79% for 24 h. Densities of five ionic liquids were determined between 283.15 and 333.15 K. Then the densities of five binary system (ILs/acetonitrile) were explored between 283.15 and 333.15 K, the type of the ionic liquid, the concentration of five ILs in CH3CN, and the effect of temperature on the binary systems, were correlated with the measured data.
