Salting effect on the liquid–liquid equilibrium for the ternary system water + methanol + methyl acetate at 283.15 K

Liquid–liquid equilibrium (LLE) data for the ternary system of water + methanol (MeOH) + methyl acetate (MA) and the quaternary system of water + MeOH + MA + calcium chloride (CaCl2) have been measured at 283.15 K under atmospheric pressure. The liquid-phase splitting of water + MeOH + MA can be enhanced by the addition of CaCl2. Separation factors at different CaCl2 concentrations were calculated and compared. In addition, the experimental data were correlated with the improved Eisen–Joffe equation.
