Liquid–liquid equilibria for systems of water + methanol + methyl anthranilate at several temperatures

Liquid–liquid equilibria (LLE) data for the systems of water + methyl anthranilate and water + methanol + methyl anthranilate were measured under atmospheric pressure over the temperature range of 298.15–323.15 K. Phase diagrams were obtained by determining solubility and tie-line data. The reliability of the experimental tie-line data was determined through the Bachman plots. The data were correlated using the NRTL and UNIQUAC models. Average RMSD obtained from the UNIQUAC and NRTL model were 0.0082 and 0.135, respectively. The correlated results were in agreement with the experiment data, though the average deviations from the UNIQUAC model are slightly smaller than those from the NRTL model.

► We measure LLE data for two systems including methyl anthranilate. ► We determine the reliability of experimental tie-line data through Bachman plots. ► We use the NRTL and UNIQUAC models to correlate the experimental data. ► The correlated results are in agreement with the experiment data. ► Average deviations from UNIQUAC are slightly smaller than those from NRTL.
