| Abstract: | Using the binary interaction parameter Q_(EN) obtained from simultaneous calculation of thermodynamic properties such as vapor-liquid equilibria and excess enthalpy etcetera of binary alcohol + hydrocarbon systems and carboxylic acid + hydrocarbon systems by associated Martin-Hou equation of state, the excess Gibbs free energies of 15 binary alcohol + hydrocarbon systems and 7 binary carboxylic acid + hydrocarbon systems are predicted by two methods. Compared with the corresponding experimental results, the average relative deviation of the predicted results for these systems by method one is 2.42%, the corresponding average relative deviation by method two is 2.46%. |
