摘要
Dialkylimidazolium ionic liquids (ILs) [bmim]PF6,[bmim]BF4,and alkylpyridine IL [bupy]BF4 were obtained by super critical fluid (SCF) CO2 extraction.The solubilities of naphthalene,phenanthrene,diphenyl,DBT and diphenyldisulfide in [bmim]PF6,[bmim]BF4 and [bupy]BF4,akylbenzene in [bmim]PF6 and [bmim]PF6 in akylbenzene were determined by high performance liquid chromatography (HPLC).Solubility experimental data of solid liquid equilibrium (SLE) were correlated by means of NRTL equation.The results indicate that NRTL is appropriate for the behaviour of these SLE and the average deviation is 3.86%—9.94%.
