Excess molar volumes for dimethyl carbonate + heptane, decane, 2,2,4-trimethylpentane, cyclohexane, benzene, toluene, or tetrachloromethane

Excess molar volumes V E at atmospheric pressure and at 298.15 K for dimethyl carbonate+heptane, decane, 2,2,4-trimethylpentane, cycloherane, benzene, toluene, or tetrachloromethane have been calculated from densities measured with a vibrating-tube densimeter. The V E are positive forall the systems over the whole mole-fraction range. These results, together with previously published excess molar enthalpies H E , suggest interactions between carbonate and hydrocarbons which are stronger with aromatic hydrocarbons than with aliphatic ones
