The solubility of carbon dioxide (CO2) in three different ionic liquids (ILs): 1-ethyl-3-methylimidazolium 1,1,2,2-tetrafluoroethanesulfonate ([EMIM][TFES]), 1-butyl-3-methylimidazolium 1,1,2,2-tetrafluoroethanesulfonate ([BMIM][TFES]), and 1-benzyl-3-methylimidazolium 1,1,2,2-tetrafluoroethanesulfonate ([BNMIM][TFES]) were measured. Measurements were done at temperatures ranging from 303.2 to 373.2 K (323.2 to 373.2 K for [BNMIM][TFES]) at pressures from 0.80 to 36.80 MPa. Measured data show that pressure, temperature, and characteristics of cation of ILs ([EMIM], [BMIM], and [BNMIM]) affect its CO2 solubility. We determined the CO2 solubility of fixed CO2 mole fractions for three ionic liquids. Among the three ILs, CO2 solubility intensity was ranked [BMIM][TFES] > [EMIM][TFES] ≈ [BNMIM][TFES]. The Peng–Robinson equation of state, the conventional van der Waals one-fluid mixing rule, and the modified Lydersen–Joback–Reid method were used to correlate the experimental data. The average absolute deviations of pressure were 0.0164 for CO2 + [EMIM][TFES], 0.0361 for CO2 + [BMIM][TFES], and 0.0251 for CO2 + [BNMIM][TFES] systems.

在1,1,2,2-四氟乙烷磺酸根阴离子型离子液体中的CO 2溶解度：[EMIM] [TFES]，[BMIM] [TFES]和[BNMIM] [TFES]
二氧化碳（CO 2）在三种不同离子液体（IL）中的溶解度：1-乙基-3-甲基咪唑鎓1,1,2,2-四氟乙烷磺酸盐（[EMIM] [TFES]），1-丁基-3-甲基咪唑鎓测量了1,2,2,4-四氟乙烷磺酸盐（[BMIM] [TFES]）和1,1,2,2-四氟乙烷磺酸1-苄基-3-甲基咪唑鎓（[BNMIM] [TFES]）。在303.2至373.2 K的温度（[BNMIM] [TFES]为323.2至373.2 K）的温度下，在0.80至36.80 MPa的压力下进行测量。实测数据表明，IL的压力，温度和阳离子特性（[EMIM]，[BMIM]和[BNMIM]）会影响其CO 2溶解度。我们确定了三种离子液体的固定CO 2摩尔分数的CO 2溶解度。在三个IL中，CO 2溶解度强度的等级为[BMIM] [TFES]> [EMIM] [TFES]≈[BNMIM] [TFES]。使用了Peng-Robinson状态方程，常规的Van der Waals一流体混合法则和改进的Lydersen-Joback-Reid方法来关联实验数据。对于CO 2 + [EMIM] [TFES]，平均压力绝对偏差为0.0164，对于CO 2 + [BMIM] [TFES]为0.0361，对于CO 2 + [BNMIM] [TFES]系统为0.0251。
