abstract The solubility of adamantane was measured in eight phosphonium-based ionic liquids (ILs) having cations with different alkyl chain lengths, namely, tributyl(methyl)phosphonium, triisobutyl(methyl)phosphonium, tetraoctylphosphonium, and tetradecyltrihexylphosphonium, combined with several anions, namely, bromide, chloride, dicyanamide, methanesulfonate, methylsulfate, bistriflamide, and tosylate. The experimental measurements were carried over the temperature range from (380 to 463) K and at pressures close to 0.1 MPa. The solubility of adamantane was shown to be essentially dependent on the alkyl chain length of the IL cation and, to a lesser extent, oil the nature of the IL anion. In general, higher solubilities of adamantane were observed with ILs presenting more hydrophobic character.
