| 제목 | High-pressure solubilities of carbon dioxide in 1-ethyl-3-methylimidazolium cation based ionic liquids: [EMIM][Ac], [EMIM][Cl], [EMIM][MeSO4] |
| 초록 | The solubility of CO2 was measured in three different 1-ethyl-3-methylimidazolium cation based ionic liquids: 1-ethyl-3-methylimidazolium acetate ([EMIM][Ac]), 1-ethyl-3-methylimidazolium chloride ([EMIM][Cl]), 1-ethyl-3-methylimidazolium methyl sulfate ([EMIM][MeSO4]). The CO2 solubility was determined by the measurement of the bubble-point or cloud-point pressure. The temperature range was from 303.15 to 403.15 K and the pressure range was from 0.45 to 48.6 MPa. The results of this work show that the solubility of CO2 in ionic liquids increased with pressure, decreased with temperature, and was also affected by the different anions. The solubility is determined by CO2 mole fraction in ionic liquids, and the order of magnitude of the CO2 solubility was found to be [EMIM][Ac] ＞ [EMIM][MeSO4] ＞ [EMIM][Cl]. To correlate of the experimental data, we used PR-EoS with one fluid mixing rule and the modified Lydersen-Joback-Reid method. The average absolute deviations of pressure were 0.0231 for CO2 + [EMIM][Ac], 0.0141 for CO2 + [EMIM][Cl], and 0.0275 for CO2 + [EMIM][MeSO4] systems. |
