Ionic liquids are salts of an organic cation and a wide variety of inorganic anions. The interest in these liquids lies in their potential towards replacing traditional solvents used in various reactions. Our research focused on the solubility of the ionic liquid trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)amide in supercritical CO2 (scCO2). Steady state emission spectra, using coumarin 153, were recorded at CO2 pressures ranging from 1040-3200 psi, at 323K. The spectra show that a partition exists between a CO2 rich phase and an ionic liquid phase. This partition, along with shifts of the emission spectra, provides evidence of the dissolution of the ionic liquid in scCO2. This presentation will focus on the preliminary results of our research as well as detail upcoming areas of investigation.
