摘要：

Vapour pressures of(butanone + 2-butanol) at eight temperatures between T = (278.15 and 323.15)K were measured by a static method. Excess enthalpies and volumes were also measured at T = 298.15 K. The reduction of the vapour pressures to obtain activity coefficients and excess molar Gibbs energies was carried out by fitting the vapour pressure data to the Redlich-Kister correlation according to Barker's method. The thermodynamic properties of the mixtures of alcohols in butanone and in n-hexane are compared with the available data and discussed. (C) 1999 Academic Press.
