The total solubility parameter δ = (E/V m ) 1 / 2 is related to the individual components through δ 2 = δ d 2 + δ p + δ h 2 . Unfortunately, although E (and thus δ) may be derived from thermodynamic studies, this is not the case for the individual components δ k which are not measurable quantities.
The Hildebrand solubility parameter (δ) provides a numerical estimate of the degree of interaction between materials and can be a good indication of solubility. |
Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 as a way of predicting if one material will dissolve in another ... |

The units of solubility parameters are MPa½. Older references use (cal/cc)½ which are a factor of 2.0455 smaller. |
The solubility parameter is a numerical value that indicates the relative solvency behavior of a specific solvent. It is derived from the cohesive energy ... |
