使用改进的平衡蒸馏器测量含有离子液体 (IL) 1-乙基-3-甲基咪唑啉四氟硼酸盐 ([EMIM][BF4]) 和溶质的二元系统的蒸气压，研究的溶质是苯、甲苯、噻吩和水。结果表明，IL[EMIM][BF4]对二元体系的蒸气压产生明显的影响，并且蒸气压随着温度的升高而增大。二元混合物（即[EMIM][BF4]+苯、[EMIM][BF4]+噻吩、[EMIM][BF4]+甲苯）的蒸气压首先随着溶质摩尔分数的增加而增加，然后几乎保持稳定。然而，水和[EMIM][BF4]的混合物的蒸气压随着水摩尔分数的增加而线性增加。将二元系统的蒸气压实验数据与真实溶剂类导体筛选模型（COSMO-RS）模型的预测值进行比较。结果表明 COSMO-RS 模型给出了定量...
The vapor pressures for binary systems containing the ionic liquid (IL) 1-ethyl-3-methylimidazoliun tetrafluoroborate ([EMIM][BF4]) and a solute were measured with a modified equilibrium still, and the solutes investigated were benzene, toluene, thiophene, and water. The results indicate that the IL [EMIM][BF4] produces an obvious effect on the vapor pressures of binary systems, and the vapor pressures increase with the temperature. The vapor pressures of binary mixtures (i.e., [EMIM][BF4] + benzene, [EMIM][BF4] + thiophene, and [EMIM][BF4] + toluene) first increase with the increase of mole fraction of the solute, and then almost keep stable. However, the vapor pressures of the mixture of water and [EMIM][BF4] increase linearly with the increase of mole fraction of water. The vapor pressure experimental data for the binary systems were compared with the predicted values by the conductor-like screening model for real solvents (COSMO-RS) model. The results demonstrate that the COSMO-RS model gives quantita...
