This study comprehensively analyzes the empirical relationships between polarizability measurements, such as refractivity index and molar refraction, or the length of the homologous chain (HCL), and the dispersive solubility parameter (δD). The authors investigated the correlation between these parameters by utilizing a database encompassing various chemical groups across a range of aliphatic and aromatic molecules. An innovative approache enhaces the well known relationship between the the dispersive solubility parameter (δD) and the Lorentz-Lorenz function, adjusting the dispersive solubility parameters by the ratio of coordination numbers and molar volumes as correction factors. Notably, the adjusted δD demonstrated a strong linear correlation with MR, suggesting that MR can be a reliable predictor for δD. This was further substantiated by the strong correlation coefficients obtained (such as an adjusted R-Square of 0.866), indicating the robustness of our empirical models. In conclusion, our research provides new insights into the solubility behaviour of molecules with the derived empirical relationships offering a valuable tool for predicting solubility parameters. These findings have practical implications for solvent selection, understanding liquid behaviours, and the design of chemical processes and materials.
