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

16/12/2015· Tetrahydrofuran (THF), methyl ethyl ketone (MEK), N, N -dimethylformamide (DMF), cyclohexanone, and cyclopentanone were tested for separating PVC from PET at different temperatures. THF dissolved PVC at 20 °C, while cyclohexanone and cyclopentanone did so at 40 °C. Traces of PVC remained on the PET fibers when DMF was used.

20/9/2014· Hansen''s approach is the most popular one wherein solvents are described by 3 parameters corresponding to dispersion (δd), polar (δp) and hydrogen bonding (δh) interactions. The main methods to predict the values of Hansen solubility parameters are based on group contributions and thus fail in the description of complex molecules.
