Abstract The excess molar volumes V m E at atmospheric pressure and at 25°C for binary mixtures of diethyl carbonate with n-heptane, n-decane, n-tetradecane, 2,2,4-trimethylpentane, cyclohexane, benzene, toluene, or tetrachloromethane have been obtained over the whole mole-fraction range from densities measured with a vibrating-tube densimeter. The V m E are positive for all the systems investigated, except for the mixture with toluene which is negative. The results for V m E together with data previously published on excess molar enthalpies H m E and excess molar Gibbs energies G m E , suggest interactions between carbonate and hydrocarbons which are stronger with aromatic than with aliphatic hydrocarbons.
