【摘要】 首次使用修正的Wilson模型关联四类对拉乌尔定律呈现不同偏差的含离子液体1-乙基-3-甲基咪唑双（三氟甲基磺酰基）亚胺[EMIM][（CF₃SO₂）₂N]的二元体系汽液相平衡数据。利用从二元体系回归的模型参数预测了2-丙醇+水+[EMIM][（CF₃SO₂）₂N]的汽液平衡数据,总压的相对均方根偏差为8.36%。结果表明:修正的Wilson模型对关联和预测含离子液体的汽液相平衡数据有一定的适用性。更多还原

【Abstract】 The modified Wilson model was used for the first time to regress the vapor-liquid equilibrium data of the four binary systems containing ionic liquid [EMIM ][（ CF₃SO₂）₂N] with different deviations from Raoul ’s law. With the parameters regressed from the binary systems,the modified Wilson model was able to predict the 2-propanol + water +[EMIM][（ CF₃SO₂）₂N]vapor-liquid equilibrium data with the relative root mean square deviation between the measured and predicted pressures equal to 8. 36%. The results show that the modified Wilson model is capable to correlate and predict the vapor-liquid equilibrium data of system containing ionic liquids.更多还原
