In this work, liquid phase compositions for mixtures of water + methanol + ethyl methyl carbonate (EMC) + heptane, water + ethanol + EMC + heptane, and water + methanol + EMC, water + ethanol + EMC, and water + EMC + heptane at 25 degrees C were measured at atmospheric pressure. The modified UNIQUAC activity coefficient model was employed to correlate the experimental tie-line data, and the results were compared with ones obtained with the extended UNIQUAC model. The consistency of the measured tie-line data was ascertained by applying the Othmer-Tobias equation.
