Resumen
Baños I., Sánchez F., Pérez P., Valero J. and Gracia M., 1992. Vapour pressures of butan-1-ol with n-hexadecane between 293.18 and 323.18 K. Description of butan-1-ol+n-alkane systems by ERAS model. Fluid Phase Equilibria, 81: 165-174. Vapour pressures of butan-1-ol with n-hexadecane between 293.18 and 323.18 K were measured at about 5 K intervals by a static method. Activity coefficients were obtained by the Barker method, and molar excess Gibbs energies were fitted to a Padé 3/1. Experimental molar excess Gibbs energies, at 298.15 and 318.15 K, and molar excess volumes, at 298.15 K, of butan-1-ol + n-hexane, + n -octane, and + n-hexadecane are compared with predictions of an extended real associated solution (ERAS) model. The model reproduces acceptably the experimental curves of VE and gives a good description of the experimental results of GE at 298.15 K. © 1992.
