Studies of viscous antagonism, excess molar volumes, viscosity deviation and isentropic compressibility of ternary mixtures containing N,N-dimethylformamide, benzene and some ethers at 298.15 K
The densities (r) and viscosities (h) 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 (VE), viscosity deviation (Δh), antagonic interaction index (IA) and Gibbs...

| description | The densities (r) and viscosities (h) 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 (VE), viscosity deviation (Δh), antagonic interaction index (IA) and Gibbs free energy of activation for viscous flow (ΔGE) were evaluated. The speeds of sound were also measured and excess isentropic compressibilities (KsE) were calculated at the experimental temperature. The results are discussed and interpreted in terms of molecular package and specific interaction predominated by hydrogen bonding. |
