ABSTRACT
Binary liquid-liquid equilibria for 10 systems containing an ionic liquid (1-(3-hydroxypropyl)pyridinium bis(trifluoromethylsulfonyl) amide and 1-(3-hydroxypropyl)pyridinium trifluorotris(perfluoroethyl)phosphate) with a hydrocarbon (n-hexane, n-heptane, cyclohexane, benzene, toluene) were measured by dynamic method. The influence of anion structure of 1-(3-hydroxypropyl)pyridinium cation based ionic liquids on solubility of aliphatic and aromatic hydrocarbons is discussed.
