ABSTRACT
The concentrations of naphthalene in CO2-rich phase for the ternary system CO2 + [bmim][PF6] + naphthalene were determined by a static method with online high-pressure ultraviolet detection, for the naphthalene molality in the liquid phase ranging from 0.0169 to 0.378 mol/kg, and within temperature and pressure ranges of 313 333K and 8 20MPa. It was found that naphthalene concentration in CO2-rich phase decreased regularly with decreasing naphthalene molality in the liquid phase. All the solubility data were correlated by Chrastil s association model and the mean relative deviation was 14.9%.
