Applications of a preferential–solvation index (PSI) for comparing analogous binary mixtures with ionic liquids (ILs) are described with the analysis of more than sixty examples from the literature. Interesting trends and patterns are revealed, confirming conclusions based on more elaborate treatments, or disclosing puzzling discontinuities by comparison of analogous mixtures. The obtained trends also question the meaning of fitting parameters from classic models of preferential solvation and the existence of postulated entities that are hard to be conceived in binary mixtures of ILs.

优先溶剂化指数 (PSI) 在二元混合物与离子液体比较中的应用

通过对文献中 60 多个示例的分析，描述了优先溶剂化指数 (PSI) 在比较类似的二元混合物与离子液体 (IL) 中的应用。揭示了有趣的趋势和模式，证实了基于更精细处理的结论，或通过比较类似混合物揭示了令人费解的不连续性。所获得的趋势也质疑了来自优先溶剂化的经典模型的拟合参数的含义，以及难以在 IL 的二元混合物中设想的假定实体的存在。
