摘要：
Vapour pressures by a static method of n-hexane, n-butan-1-ol, and (n-butan-1-ol + n-hexane) at temperatures between 283.10 K and 323.12 K at about 5 K intervals, were measured. Activity coefficients and excess molar Gibbs free energies GEm were calculated by Barker's method. Three different types of equations for GEm were used for fitting the experimental results. For alcohol-dilute mixtures, formation of an azeotropic mixture with a minimum boiling temperature was observed. © 1992 Academic Press Limited All rights reserved.
