Abstract
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.
Highlights
Mixed solvents rather than single pure liquids, are extensively used in industrial process as they provide a wide range of solvent with variable physical properties
Acetonitrile is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene. It is used as a medium-polarity solvent that is miscible with water and a range of organic solvents, but not saturated hydrocarbons
The present study reports the experimental values of viscosity (η) for the binary mixture of acetonitrile with 2 ethoxyethanol and 2butoxyethanol at temperatures 293K, 303K and 313K over the whole composition range
