제목 | High pressure Phase behavior of CO2 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 0.08–29.27 MPa and 303.2–373.2 K. 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. The overall average absolute deviations of pressure (AAD-P) were 0.0204, 0.0275, and 0.0227 for CO2 + [EMIM][BETI], CO2 + [BMIM][BETI], and CO2 + [HMIM][BETI] systems, respectively. |
