A simultaneous correlation of vapour pressures and thermal data: application to 1-alkanols

Abstract

R∪žička, K. and Majer, V., 1986. A simultaneous correlation of vapour pressures and thermal data: application to 1-alkanols. Fluid Phase Equilibria, 28: 253-264 Possibilities of simultaneous correlation of vapour pressures and thermal data (enthalpy of vaporization and difference between heat capacity of idea gas and liquid) are investigated. This approach permits a reliable evaluation of vapour pressures and/or enthalpies of vaporization far below the normal boiling point and can serve also as a consistency test of experimental data. A simple procedure using smoothed input data is proposed which can be implemented in a software of the data bank of thermodynamic properties. The method is demonstrated on a group of eight 1-alkanols.
