AB This work aims to experimentally determine the excess molar enthalpies at 298.15 K and atmospheric pressure for the ternary mixture {x1 methyl tert-butyl ether (MTBE) + x2 1-pentanol + (1 − x1 − x2) heptane} and the corresponding binary system {x 1-pentanol + (1 − x) heptane}, across the whole composition range. The excess molar enthalpy of the ternary system is positive throughout the composition range. Except for a region around compositions rich in 1-pentanol, the ternary contribution to the excess molar enthalpy is also positive and its representation is asymmetric. A systematic review of the currently accessible literature on excess molar enthalpy for the ternary mixtures containing ethers with 1-alkanol and 1-alkane was conducted. According to our searches, no previous experimental measurements of excess enthalpy for the ternary combination under study have been reported. The ternary excess enthalpy values and the involved binary mixtures were estimated using the UNIFAC group contribution model. Furthermore, several empirical equations for estimating ternary properties from binary results were tested against the experimental data to evaluate their predictive accuracy for ternary properties.
