| Abstract: | Excess enthalpies and excess heat capacities of { x 2-butanone + (1 ? x)1,4-dioxane}, and { x cyclohexanone, or 2-butanone, or 1,4-dioxane + (1 ? x)1,2-dimethoxyethane} were measured atT = 298.15 K. Excess enthalpies were negative for { x 2-butanone + (1 ? x)1,2-dimethoxyethane}, and negative with a small positive part in the region ofx > 0.8 for { x cyclohexanone + (1 ? x)1,2-dimethoxyethane}, whereas excess enthalpies of { x 2-butanone + (1 ? x)1,4-dioxane} were positive as for { x cyclohexanone + (1 ? x)1,4-dioxane} previously reported. Excess enthalpies of {x 1,4-dioxane + (1 ? x)1,2-dimethoxyethane} were positive. The results were compared with the systems reported earlier. Excess heat capacities are positive for { x 2-butanone + (1 ? x)1,2-dimethoxyethane} and { x cyclohexanone + (1 ? x)1,2-dimethoxyethane}, and negative for { x 2-butanone + (1 ? x)1,4-dioxane} and { x 1,4-dioxane + (1 ? x)1,2-dimethoxyethane}. The last mixture shows a W-shaped curve of excess heat capacity. |
