| 제목 | Hydrate-Containing Phase Equilibria for Mixtures of Carbon dioxide+ 1-butyl-3-methylimidazolium tetrafluoroborate ([C4min][BF4]) + water |
| 초록 | Ionic liquids (ILs), a promising alternative for organic solvent, were found to have the inhibition effect on the CO2 hydrate formation [1]. In this study we measured the dissociation temperature of CO2 hydrate containing 1-butyl-3-methylimidazolium tetrafluoroborate ([C4min][BF4]) at constant pressure and determined loading composition of all components. With 0.1 molar ratio of IL to aqueous solution, three-phase equilibrium conditions in Lw-H-V below the vapor pressure of CO2 and Lw-H-Lg above were determined by varying the relative amount of CO2 to IL-H2O mixture. The result shows that in spite of its small amount, ILs inhibit the CO2 hydrate formation. [1] Q. Chen, Y. Yu, P. Zeng, W. Yang, Q. Liang, X. Peng, Y. Liu, Y.
