| Abstract | Liquid-liquid equilibria for hexafluorophosphate ionic liquids with 1-alkyl-3-methylimidazolium family of cations: 1-butyl-3-methylimidazolium, [bmim](+), 1-hexy1-3-methylimidazolium, [hmim](+), 1-octyl-3methylimidazolium, [omim](+) with polyhydric alcohols: 1,2-ethanediol, 1.2-propanediol, 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,3-propanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol have been measured using the cloud point method. The influence of different characteristics of alcohols and ILs, including cation alkyl chain length, alcohol chain length, and relative position of the both OH groups in alcohol were studied. In general, the same type of the phase behavior is observed in all cases showing upper critical solution temperature but the impact of the above-mentioned factors is highly diversified.
