On the basis of the Clausius - Clapeyron equation and the kinetic theory of liquid we obtained γb= 4.187×10-3(18.2Tb+3.2Tc—780) And according to the rules of semi - metal structural theoretic model of organic molecules and the theoretic and experimental results from molecular physics, spectroscopy and matrix method, a new theoretic equation (Eq.5) for calculating enthalpy of vaporization γb at normal boiling point is derived. Eq5 is simple and reliable for calculating γb. The values Ci and Ce, required in this equation can be found in Table 3. This equation can be applied both to nonpolar and polar liquids. The average error from experimental data is 0.8% based upon 228 compounds of 36 types of structures. It is far better than all other methods in literature. The physical essence of Eq.5 is clear and definite. This work is of important in the development of engineering thermodynamics and its practical application.
