A flow microcalorimeter of the Picker design was used to measure excess molar enthalpies H E m at the temperature 298.15 K over the whole composition range of several binary liquid mixtures formed from an alkanoic acid and either n-heptane, or cyclohexane, or benzene. The alkanoic acids selected wer

β¦ Synopsis
Measurements of excess enthalpies at T s 298.15 K are reported for binary mixtures of Ε½ . 2-ethoxyethanol q n-octane, or cyclohexane, or benzene . The excess enthalpies of all these Ε½ . systems were found to be positive. The 2-ethoxyethanol q benzene system shows asymmetric behaviour of H E with respect to the mole fraction of 2-ethoxyethanol. However, the other m two systems show nearly symmetric behaviour. This asymmetric behaviour of H E for the m system containing benzene is discussed.
