✦ Synopsis
Microcalorimetric measurements of excess enthalpies at the temperature 298.15 K are reported for the two ternary mixtures (methyl 1,1-dimethylpropyl ether + 2,3-dimethylbutane + decane) and (methyl 1,1-dimethylpropyl ether + cyclohexane + decane). Smooth representations of the results are presented and used to construct constant-enthalpy contours on Roozeboom diagrams. Comparisons of the experimental results with estimates based on the Flory theory of mixtures are also described.

The results were compared with the values of H E m for the related mixtures, and the possible hydrogen bonding between the alkyne and the ether noted. Various theories of liquid mixtures were fitted with the results. The H E m results were discussed in terms of the NRTL and UNIQUAC models, and were
