Flow-calorimetric measurements of molar excess enthalpies at 298.15 K and 313.15 K and atmospheric pressure have been performed for binary mixtures of tert-amyl-methyl ether (TAME) with n-heptane, n-octane, iso-octane and methanol. The experimental results are used to test the applicability of the extended real associated solution (ERAS) model to describe thermodynamic excess properties.
