To make use of the thermodynamic model of the formation of solutions containing alcohol and the approach to release and charge attractive potential energy between two components as we proposed in previous work, the equation of excess Gibbs free energy is also established, which can avoid calculating the contribution of chemical action to the excess Gibbs free energy and make the derivation much simpler. The model can simultaneously be used to correlate the excess enthalpy, excess Gibbs free energy and excess entropy for all kinds of alcoholic solutions including aqueous solutions of alcohol. The correlation results for 17 typical systems show that the consistency with experimental data is very satisfactoiy.
