Resumen
The vapor-liquid phase equilibria for the n-hexane-1-butanol system at 323.15, 338.15, and 348.15 K have been measured using a Fischer recirculating still. Excess molar Gibbs energies GEPm and activity coefficients were calculated. Thermodynamic consistency was tested by two methods and the results were correlated by use of the Wilson equation. The system exhibits positive GE m values over the entire composition range in the temperature range studied and an azeotrope exists at all three measured temperatures. © 1989. 50 1-2 201 208 Berro, Rogalski, Péneloux, Excess Gibbs energies and excess volumes of 1-butanol + n-hexane and 2-methyl-1-propanol + n-hexane binary systems (1982) Journal of Chemical & Engineering Data, 27, pp. 353-355 Boublík, Fried, Hála, (1973) The Vapour Pressures of Pure Substances, , Elsevier, New York Brown, Fock, Smith, The thermodynamic properties of solutions of normal and branched alcohols in benzene and n-hexane (1969) J.
