From comparison of calculated value and experimental data, the average of AAD (Overall-average deviation) of binary LLE calculation for 10 systems containing ILs is 3. 228% with NRTL model and 2. 691% with UNIQUAC model.

• 通过比较计算值与实验值；结果令人满意；NRTL和UNIQUAC方程计算得到的10个体系的全体平均误差(AAD；Overall-average deviation)的平均值分别为3.；228%25和2
