✦ Synopsis


Measurements of excess molar enthalpies at the temperature 298.15 K in a flow microcalorimeter, are reported for the ternary mixtures

where Ξ½ = 5 and 6. Smooth representations of the results are described and used to construct constant-enthalpy contours on Roozeboom diagrams. It is shown that useful estimates of the ternary enthalpies can be obtained from the Liebermann-Fried model, using only the physical properties of the components and their binary mixtures.

Excess molar enthalpies H E m at T = 298.15 K are reported for (N -methyl-2pyrrolidinone + chlorobenzene, or 1,2-dichlorobenzene, or 1,3-dichlorobenzene, or 1,2,4,-trichlorobenzene). The values of H E m were obtained by using the flow calorimetric method. All the mixtures, over the whole composition
