The ternary mixtures exhibit large positive deviations for both properties investigated. Ternary H E and C E data were poorly predicted by rules which m p, m empirically combine the same data of the pertinent binary mixtures. The H E data were m instead satisfactorily predicted by semi-empirical equations such as UNIQUAC and Wang, but not by UNIFAC.

Excess molar volumes V E m and excess molar heat capacities C E p,m were determined for mixtures of benzonitrile with chlorobenzene, or benzene, or toluene at the temperatures 298.15 K and 303.15 K. For all the systems the values of V E m were negative over the whole range of compositions and values
Excess molar volumes V E m have been calculated from measured density values over the whole composition range at T = 298.15 K and atmospheric pressure for six {N -methyl-2-pyrrolidinone + 1,1-dimethylethyl methyl ether, or dipropyl ether, or 1,1-dimethylpropyl methyl ether, or diisopropyl ether, or
