Abstract
The solubility of CO2 in two inexpensive ionic liquids,
tributylmethylammonium methylsulfate [TBMN][MeSO4] and tributylmethylphosphonium
methylsulfate [TBMP][MeSO4], has been studied
experimentally. A synthetic method was used to measure bubble-point
pressures up to 13 MPa for a temperature range of (313 to 368) K. The
solubility of CO2 in [TBMP][MeSO4] was slightly higher than in
[TBMN][MeSO4], but CO2 solubilities in both the ionic liquids were
surprisingly higher than in the imidazolium analogue 1-butyl-3-methylimidazolium
methylsulfate [bmim][MeSO4]. The relatively high melting
points of the used ionic liquids may limit their application in CO2 capture
processes. |
