The cohesive energy density
WebDefined as the square-root of the cohesive energy density (c) of the solvent, the Hildebrand solubility parameter describes the degree of solubility for nonpolar or slightly polar substances without hydrogen bonding. It also describes the amount of energy required to evaporate one-unit volume of a liquid (Hildebrand and Scott, 1964 ).
