Abstract
Solubility results of carbon dioxide ($CO_2$) in two ammonium-based ionic liquids, butyltrimethylammonium bis(trifluoromethylsulfonyl)imide ([N4,1,1,1][$Tf_2N$]) and methyltrioctylammonium bis(trifluoromethylsulfonyl)imide ([N1,8,8,8][$Tf_2N$]), are presented at pressures up to approximately 45 MPa and temperatures ranging from 303.15 K to 343.15 K. The solubility was determined by measuring bubble point pressures of mixtures of $CO_2$ and ionic liquid using a high-pressure equilibrium apparatus equipped with a variable-volume view cell. Sharp increase of equilibrium pressure was observed at high $CO_2$ compositions. The $CO_2$ solubility in ionic liquids increased with the increase of the total length of alkyl chains attached to the ammonium cation of the ionic liquids. The experimental data for the $CO_2$+ionic liquid systems were correlated using the Peng-Robinson equation of state.
