摘要：A model of the cohesive energy of liquids, which can be used to calculate the cohesive energy and solubility parameters of various liquids, has been established using a statistical thermodynamic method. Ln consideration of the strong intermolecular interactions in liquids, a hindering factor is introduced to modify the contribution of their rotation and vibration to the internal partition function. The factor is dependent on the density of liquids. The relationship between this factor and density is also derived. The results of calculation for the solubility parameters are consistent with the literature values.
