基于经典的Eyring混合物粘度方程和Wilson活度系数方程，提出了一个关联离子液体与溶剂体系粘度的半理论模型。通过对49种混合物共1560个数据点的粘度计算值与文献中的实验值进行比较，验证了模型的准确性。结果表明，类似于Wilson活度系数方程的方程可以很好地描述Eyring混合物粘度方程中的非理想项。该模型具有相对简单的数学形式，可以很容易地纳入过程模拟软件。
A semi-theoretical model based on the classical Eyring’s mixture viscosity equation and the Wilson activity coefficient equation is presented for correlating the viscosity of ionic liquids with solvent systems. The accuracy of the proposed model was verified by comparing calculated and experimental viscosity values from literatures for 49mixtures with total 1560 data points. The results show that the equation similar to the Wilson activity coefficient equation can be well applied to describe the non-ideal term in the Eyring’s mixture viscosity equation. The model has a relatively simple mathematical form and can be easily incorporated into process simulation software.
