Influence of anion structure on the liquid-liquid equilibria of 1-(3-hydroxypropyl)pyridinium cation based ionic liquid-hydrocarbon binary systems

摘要

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.
