摘要：

Vapour pressures of di-n-propylether with ethanol and with l-butanol were measured at eight temperatures between 278.15 and 323.15 K by a static method. Reduction of the vapour pressures to obtain activity coefficients and excess molar Gibbs free energies was carried out by Barker's method. Mixtures containing ethanol show azeotropy with a minimum boiling temperature. G(E), H-E, and V-E, at 298.15 K, of mixtures of di-n-propylether+methanol, +tethanol, +1-propanol, +2-propanol, and +1-butanol are compared with predictions of the ERAS model observing that the model reproduces acceptably the experimental behaviour.
