摘要：

Vapour pressures of octane and of (butan-1-ol + octane), at about 5 K intervals between the temperatures 283.16 K and 323.18 K, were measured by a precise static method. Following Barker's method, the activity coefficients and the excess molar Gibbs energies were fitted to a polynomial of degree three. Azeotropic mixtures with a minimum boiling temperature, richer in butan-1-ol with increasing temperature, were observed over the whole temperature range. © 1992 Academic Press Limited All rights reserved.
