Excess heat capacities C-p(E) of the mixtures of cyclohexanone with toluene, chlorobenzene, methylcyclohexane and 1,4-dioxane and excess enthalpies H-E Of the mixtures with chlorobenzene and 1,4-dioxane were measured at 298.15 K. Density and speed of sound of the mixture of cyclohexanone with 1,4-dioxane were also measured at 298.15 K. Thermodynamic properties of the mixtures of cyclohexanone with globular solvents are discussed with reference to the heptane systems. H-E of aliphatic systems is highly positive and their C-p(E) show various steps of W-shaped curves. H-E of 1,4-dioxane system is positive but a third of aliphatic ones and its C-p(E) is negative. H-E of aromatic systems is negative to form strong induced dipole-dipole interaction between aromatic and cyclohexanone molecules. C-p(E) of these systems changes from negative to positive with the increase of the mole fraction of aromatics. However that of chlorobenzene is large and has no negative part.
