L. Lintomen et al., Liquid-liquid equilibrium of the water plus citric acid plus 2-butanol plus sodium chloride system at 298.15 K, J CHEM EN D, 45(6), 2000, pp. 1211-1214
Liquid-liquid equilibrium data for water + citric acid + 2-butanol + NaCl a
t three different salt concentrations (5, 10, and 15 mass %) and at 298.15
K were determined. The parameters for the NRTL and UNIQUAC models were obta
ined by fitting the thermodynamic models to the experimental data.
