This article reports equilibrium data for the binary liquid‐liquid system water + methyl propyl ketone at temperatures in the range 20‐55°C, together with solubilities and equilibrium compositions of the ternary system water + acetic acid + methyl propyl ketone at 25, 35, 45 and 55°C. NRTL and UNIQUAC equations have been fitted to the experimental data for the ternary system, which are likewise compared with the values predicted by the group contribution method UNIFAC.
