Journal ArticleDOI
Thermodynamic properties of ethanol + water. I. Vapour-liquid equilibria measurements from 90 to 150°C by the static method
B. Kolbe,Jürgen Gmehling +1 more
TL;DR: In this paper, a static apparatus is described with the help of which vapour-liquid equilibria can be measured with a good precision particularly in the range of pressure 1-10 bar.
Journal ArticleDOI
Thermodynamic properties of ethanol + water II. Potentials and limits of GE models
B. Kolbe,Jürgen Gmehling +1 more
TL;DR: In this article, the authors used the maximum likelihood method to adjust the VLE-data to a mathematical model for the excess Gibbs energy of the system ethanol/water in the temperature range 30-150°C.
Journal ArticleDOI
Thermodynamic properties of ethanol and water— III. Description of the different excess functions (gE, hE, cEP) using an empirical model
TL;DR: In this paper, a modified Redlich-Kister approach with six concentration-dependent coefficients is chosen as a model equation for the excess Gibbs energy, defined in such a way that the result is a quadratic dependence of the molar excess heat capacity cEP as a function of the temperature.
Journal ArticleDOI
Limitations of modern expressions for the excess Gibbs energy
Jürgen Gmehling,B. Kolbe +1 more
TL;DR: In this paper, Gibbs energy models are used in combination with a truncated form of the virial equation to describe the phase equilibria of binary and multicomponent systems primarily as a function of composition and temperature.
