M. Bender et A. Heintz, THERMODYNAMICS OF 1-ALKANOL-ALKANE MIXTURES BASED ON PREDICTIONS OF THE ERAS MODEL(N), Fluid phase equilibria, 89(1), 1993, pp. 197-215
Five key systems have been selected by the IUPAC workshop on vapor-liq
uid equilibria of 1-alkanol+n-alkane mixtures for testing models and c
orrelation methods of thermodynamic excess properties. The five binary
systems are: methanol+hexane, ethanol+hexane, ethanol+hexadecane, but
anol+decane, and hexanol+hexane. ERAS model calculations of H(E), V(E)
, and G(E) (VLE) at 298.15 K and 323.15 K as well as LLE calculations
for methanol+hexane and for ethanol+hexadecane have been compared with
experimental data. With exception of activity coefficients at infinit
e dilution the model provides an almost quantitative description of th
e experimental data using a small number of adjustable parameters. How
ever, different values of the entropy parameter Q(AB) have to be chose
n in order to describe LLE and VLE data properly.
