| Abstract: | In the mixing process of solutes into solvents, the cavity formation energy is generally introduced into the energy balance. In this study, models for calculating this type of energy are proposed. These models are based on the Hansen's partial solubility parameters δd (MPa1/2) dispersive, δp (MPa1/2) polar and δh (MPa1/2) hydrogen-bonding, and on the internal pressure Pj (J cm?3) of the solvents. |
