THERMODYNAMICS OF BINARY MIXTURES CONTAINING ORGANIC CARBONATES .10. EXCESS MOLAR VOLUMES OF DIETHYL CARBONATE WITH HYDROCARBONS OR TETRACHLOROMETHANE AT 25-DEGREES-C

摘要

The excess molar volumes V-m(E) at atmospheric pressure and at 25 degrees 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-mE 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.
