Excess enthalpies of oxygenated compounds + hydrocarbon mixtures: Binary and ternary mixtures containing dibutyl ether (DBE), 1-butanol and 2,2,4-trimethylpentane at 298.15 K

Measurements of excess molar enthalpies at the temperature of 298.15 K and atmospheric pressure in a quasi-isothermal flow calorimeter are reported for the ternary system dibutyl ether (DBE) + 1-butanol + 2,2,4-trimethylpentane (TMP) and the corresponding binary systems. All the binary and the ternary systems show endothermic character. The Redlich–Kister equation and the NRTL and UNIQUAC models have been used to fit the experimental data for the binary and ternary systems.
