WebTable 2: Calculation of solubility parameter of nabumetone by fedor’s group substitution method δ 2 = Solubility parameter of nabumetone, (Cal/cm3)0.5 = Unit of solubility parameter Cohesive energy and molar volume of nabumetone was obtained by edor’s group substitution method, which divide the structure into different drug fragments.

WebMay 15, 2024 · The solubility parameter concept was first introduced by Hildebrand and Scott [7], so called Hildebrand solubility parameter. The γt and δt both arise from the intermolecular interactions, and thus can be divided into different components. The γt is commonly divided into dispersive (non-polar) and polar (non-dispersive) components [1]. The Hildebrand solubility parameter (δ) provides a numerical estimate of the degree of interaction between materials and can be a good indication of solubility, particularly for nonpolar materials such as many polymers. Materials with similar values of δ are likely to be miscible.
