| 제목 | A study on the CO2 solubility in bis(pentafluoroethylsulfonyl)imide ([BETI]) anion-based ionic liquids: [EMIM][BETI], [BMIM][BETI], [HMIM][BETI] |
| 초록 | We measured the CO2 solubility in three different [BETI] anion-based ionic liquids: 1-ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide ([EMIM][BETI]), 1-butyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide ([BMIM][BETI]), and 1-hexyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide ([HMIM][BETI]) in the experimental ranges of 0.1–29.3 MPa and 303.2–373.2 K. In this paper, we report the CO2 solubility in three [BETI] anion-based ILs under various experimental conditions, and compare the effect of three different cations, [HMIM], [BMIM], and [EMIM]. We determined the CO2 solubility by measuring the bubble-point pressure for a fixed CO2 mole fraction, and the order of intensity for CO2 absorption ability was [HMIM][BETI] ＞ [BMIM][BETI] ＞ [EMIM][BETI]. The Peng-Robinson equation of state (PR-EoS), the conventional van der Waals one fluid mixing rule and the modified Lydersen-Joback-Reid method were used to correlate and calculate the experimental data. Keywords: CO2 solubility, Ionic liquids, PR-EoS, [BETI] anion |
