제목 | A study on the CO2 solubility in [Tf2N] anion based ionic liquids: [BVMIM][Tf2N], [P4441][Tf2N], [N4222][Tf2N] |
초록 | In this study, three different [Tf2N] anionic ionic liquids were selected for measuring high pressure CO2 solubility. Solubility data were obtained by measuring the bubble point pressure of the mixture using a variable volume view cell. Experimental conditions were set at 10 K interval from 303.15 K to 373.15 K. The new solubility database for three ionic liquids were constructed by this work, and it is confirmed that CO2 absorption capacity is better in order of [BVMIM] [Tf2N], [P4441] [Tf2N], and [N4222] [Tf2N]. From experimental data, thermodynamic modeling was correlated through Peng-Robinson equation of state and van der Waals one fluid mixing rule to predict CO2 solubility for ionic liquids at various temperature and composition ranges. The critical properties and acentric factor of the ionic liquid were calculated using the modified Lydersen-Joback-Reid method. Keywords: CO2 solubility, Ionic liquids, PR-EoS, [Tf2N] anion |
