The effect of molecular interaction energy among different molecules in the mixed solutions significantly depends upon the size of individual molecule size and molecular arrangement. In order to compensate these effects on the existing method, a new method of representing the relationship of temperature and compositions of each phase(vapor and liquid phases in equilibrium) and azeotropic mixture is proposed. The optimized models of the RSM(response surface methodology) and MRSM(modified response surface methodology) are briefly described. The applications of these models to the solution thermodynamics are also explained.
