(Liquid plus liquid) equilibria of oxygenate fuel additives with water: (water plus diisopropyl ether plus 2,2,4-trimethylpentane plus ethanol) and (water plus diisopropyl ether plus 2,2,4-trimethylpentane plus 2-propanol)
The tie line of (water + ethanol + diisopropyl ether + 2,2,4-trimethylpentane), (water + 2-propanol + diisopropyl ether + 2,2,4-trimethylpentane), and (water + 2-propanol + 2,2,4-trimethylpentane) have been measured at a temperature of 298.15 K and ambient pressure. The experimental ternary and quaternary (liquid + liquid) equilibria were correlated with the modified UNIQUAC activity coefficient model including binary and multibody interaction parameters.
