Excess molar volumes and viscosities of mixtures containing dimethylformamide (DMF)‎ with benzene, o- xylene, 1, 4- dioxane and tetrahydrofuran at 298.15 K.

الملخص EN

Measurements of excess molar volumes VE , viscosities η , excess viscosities Δ ln η and excess molar activation energies of viscous flow ΔGE , are reported for binary mixtures of dimethylformamide (DMF) with , benzene , o-xylene , 1, 4- dioxane and tetrahydrofuran are reported from density and viscosity measurements at 298.15 k and at atmospheric pressure over the entire composition range .

The excess values are positive for the mixture (DMF+ polar solvent) and negative deviation from ideality for the mixture (DMF + non-polar solvent) over the whole composition range and discussed in the light of molecular interaction in the mixture.
