| Abstract: | The binary systems of water with methanol, ethanol, and 1-propanol and triethylamine with methanol, ethanol, 1-proponal, and 1-butanol are modeled using the rigid lattice solution theory developed by Guggenheim. Numerous possible model configurations are considered. It is shown that several model specifications are capable of describing a limited number of thermodynamic properties, but a unique model is capable of describing all available data including total and partial pressures, excess free energy, equilibrium compositions, activity coefficients, and heats of mixing. The effects on predictive reliability of various coordination number specifications and sensitivity of interaction energies to temperature changes are studied. ... |
