Abstract
Liquid-liquid equilibrium (LLE) data were measured at 298.15 K for some aliphatic alcohols + water + potassium carbonate systems. The alcohols used were ethanol, 1-propanol, 2-propanol and 2-methyl-2-propanol. The LLE data were correlated with the Othmer-Tobias and Bancroft equations. A calculated method was also proposed to correlate the experimental tie-line data. This method is based on the Wilson model for alcohol + water mixture, the Pitzer equation for electrolyte solution and an empirical equation for the binodal curves.
