Excess molar enthalpies of the ternary mixtures (1-hexene plus tetrahydrofuran or 2-methyltetrahydrofuran plus methyl tert-butyl ether) at the temperature 298.15 K
Microcalorimetric measurements of excess enthalpies at the temperature T = 298.15 K are reported for the binary mixture, (x(1)C(6)H(12) + x(2)C(4)H(8)O) and the two ternary mixtures {x(1)C(6)H(12) + x(2)(C4H8O or C5H10O) + x(3)(C5H12O)}. Smooth representations of the results are presented and used to construct constant excess molar enthalpy contours on Roozeboom diagrams. It is shown that good estimates of the ternary enthalpies can be obtained from the Liebermann and Fried model, using only the physical properties of the components and their binary mixtures.
