Hildebrand solubility

WebThe Hildebrand solubility parameter is defined as the square root of the cohesive energy density given by the following equation: δ = (E / V)1/2 Where E is the energy of vaporization, V = Volume and δ is the Hildebrand Solubility Parameter. This value is generally reported in MPa½, but is also 2.0455 times larger than (cal/cm3)½. WebAug 3, 2016 · The simulated values of Hildebrand solubility parameter of glycerol decrease with raising temperature because the cohesive forces weaken. To the best of our knowledge, this work for the first time calculates the potential of mean force, viscosity, and Hildebrand solubility parameter of glycerol by MD simulation. Introduction
