Liquid−Liquid Equilibria of the System Water + 2-Propanol + 2,2,4-Trimethylpentane at 25 °C

Abstract

Liquid−liquid equilibria of the system water + 2-propanol + 2,2,4-trimethylpentane at 25 °C were obtained to evaluate 2,2,4-trimethylpentane as an extraction agent in aqueous solutions of 2-propanol. The experimental data were fitted using the NRTL and UNIQUAC equations. Equilibria predictions, applying the UNIFAC method, were also made with the use of liquid−liquid equilibria specific parameters.
