The Hildebrand solubility parameter is the square root of the cohesive energy density: $${\displaystyle \delta ={\sqrt {\frac {\Delta H_{v}-RT}{V_{m}}}}.}$$ The cohesive energy density is the amount of energy needed to completely remove unit volume of molecules from their neighbours to infinite separation … See more The Hildebrand solubility parameter (δ) provides a numerical estimate of the degree of interaction between materials and can be a good indication of solubility, particularly for nonpolar materials such as many See more The conventional units for the solubility parameter are (calories per cm ) , or cal cm . The SI units are J m , equivalent to the pascal . 1 calorie is equal to 4.184 J. 1 cal cm = (523/125 J) (10 m) = (4.184 J) (0.01 m) = 2.045483 10 J m = 2.045483 MPa . See more • Abboud J.-L.
