### Hansen Solubility Sphere

According to Hansen 1, PS has an interaction radius of approximately 12.7 and its partial solubility parameters are ( δd, δp, δh) = (21.3, 5.7, 4.3) and those of acetone are (15.5, 10.4, 7.0). This gives Ra = { (2·15.5 - 2·22.3) 2 + (10.4 - 5.8) 2 + (7.0 - 4.3) 2 } 1/2 = 12.8 → Ra / R0 = 12.8 / 12.7 ≈ 1.0

The basic concept of solubility parameter was developed by Hildebrand and Scott. (“The Solubility of None-electrolytes.1964) The free energy of mixing is written as ΔG=ΔH-ΔTS and if ΔG is less than 0, at that time mixing will happen. ΔH=φ1φ2V (σ1-σ2）2 φ：volume ratio、σ：SP value The SP (solubility parameter) value was first appearing in this scheme.
