Abstract

Forming part of the scientific project entitled ‘Study on physical properties of mixtures hydrocarbon+alcohol+ether like alternative fuels’, the present article reports experimental data of excess molar enthalpies for the ternary mixture {x1tert-butyl methyl ether (MTBE)+x21-pentanol+(1−x1x2)octane} and the involved binary mixture {x1-pentanol+(1−x) octane} at the temperature of 298.15 K and atmospheric pressure. No experimental excess enthalpy values were found in the currently available literature for the ternary mixture under study. The group contribution model of the UNIFAC (in the versions of Larsen, and Gmehling) were used to estimate excess enthalpy values. Several empirical expressions for estimating ternary properties from binary results were also tested.
