Excess enthalpies of oxygenated compounds plus 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. (C) 2009 Elsevier B.V. All rights reserved.
