The derivation of Hildebrand's solubility parameter and the inter-molecular forces that influence solubility are discussed. Three of these forces were incorporated into a model which consisted of … 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].
