摘要：

Vapor-liquid equilibrium data are reported for ethanol-n-heptane-isobutanol and its three constituent binary systems at 303.15 K. The measurements were made using a Van Ness apparatus, and results are reported in the form of total pressure versus liquid phase composition. The data were smoothed using Barker's method, and expressions for the excess Gibbs free energy of the liquid phase, which represent the binary and ternary results to within experimental error, are presented.
