摘要：

The densities (p) and viscosities (eta) for ternary liquid mixtures of N,N-dimethylformamide + benzene + an ether were measured as a function of composition at 298.15 K. From experimental measurements, the excess molar volumes (V-E), viscosity deviation (Delta eta), antagonic interaction index (I-A) and Gibbs free energy of activation for viscous flow (Delta G*(E)) were evaluated. The speeds of sound were also measured and excess isentropic compressibilities (K-s(E)) were calculated at the experimental temperature. The results are discussed and interpreted in terms of molecular package and specific interaction predominated by hydrogen bonding.
