Abstract

Diisopropyl ether (DIPE) could be a suitable gasoline additive. In this work, we report liquid−liquid equilibrium data for the ternary system isopropyl ether + ethanol + water at (298.15, 308.15, and 318.15) K. The parameters for the NRTL and UNIQUAC models were obtained by fitting the thermodynamic models to the experimental data. The predictive ability of the UNIFAC method was tested.
