Liquid−Liquid Equilibria for the Ternary System Water + Dodecane + 2-Butyloxyethanol in the Temperature Range from 25 °C to 65 °C

Abstract

Liquid−liquid equilibria of the ternary system water + dodecane + 2-butyloxyethanol in the temperature range from 25.0 °C to 65.0 °C were performed at atmospheric pressure. The experimental data were correlated with the UNIQUAC model and good agreement was obtained. For the system with a three-liquid-phase-coexisting region, all six UNIQUAC interaction parameters can be numerically regressed by simply minimizing the deviation of the compositions of three coexisting liquid phases.
