ABSTRACT
Liquid liquid equilibrium (LLE) data for the systems water + 1-propanol + methyl methacrylate, butyl methacrylate, and isobutyl methacrylate were determined at atmospheric pressure over a temperature range of 288.15 318.15 K. The areas of two-phase region decrease with increasing temperature for each ternary system and decrease in the mixture containing methyl methacrylate greater than butyl methacrylate or isobutyl methacrylate. The reliability of the experimental tie-line data has been tested with the Othmer Tobias and Bachman correlations. The experimental data were also compared with the values calculated by the NRTL and UNIQUAC models. Good agreement was obtained with these models. In general, the average deviations from the NRTL model are slightly smaller than those from the UNIQUAC model.
