The hildebrand solubility parameter δ
WebΔH = -n 1.n 2.z(δ 1 δ 2-0.5(δ 1 ²+δ 2 ²)) We see that the δ values capture the balance of self-liking 0.5(δ 1 ²+δ 2 ²) and the weaker unlike interaction (δ 1 *δ 2). The self-like term is the … WebThe Hildebrand solubility parameter can be used to predict whether two compounds will be miscible, as indicated by similar solubility parameter values. Thus, solubility is a key …
