ABSTRACT

Liquid-liquid equilibrium (LLE) data for the ternary system water + 1,4-dioxane + 2,6-dimethyloct-7-en-2-ol (DHM-OH) were determined at atmospheric pressure over the temperature range of (343.2 to 358.2) K. The reliability of the experimental tie-line was determined through the Othmer-Tobias correlation. The experimental data were also compared with the values correlated by the NRTL and improved UNIQUAC models. Good quantitative agreement was obtained with these models.
