With the aim to study the viscosity and density of acetronitrile with 2- ethoxyethanol and 2- butoxyethanol at temperatures 293K, 303K and 313K over the whole composition range. The experimental results were used to calculate deviation in viscosity (Δη), excess internal pressure ( E i π ) and excess enthalpy ( E m H ). These results are used to quantitatively discuss the nature of interaction taking place between the components when mixed in terms of hydrogen-bond effects, dipole-dipole interaction weak vanderwaals type dispersion force. The calculated quantities have been fitted to Redlich-Kister equation.
