Abstract
The boiling points of solutions of five binary systems are measured via ebulliometry in the pressure range of 2.05–103.3 kPa. Equilibrium vapor phase compositions, the values of the excess Gibbs energies, enthalpies, and entropies of solution of these systems are calculated. Patterns in the changes of phase equilibria and thermodynamic properties of solutions are established, depending on the compositions and temperatures of the systems. Liquid–vapor equilibria in the systems are described using the equations of Wilson and the NRTL (Non-Random Two-Liquid Model).
