✦ Synopsis

Ž

. Ž Vapour pressures of butanone q 2-butanol at eight temperatures between T s 278.15 and . 323.15 K were measured by a static method. Excess enthalpies and volumes were also measured at T s 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.
