Temperature Dependent Studies of Interaction in Sixteen Binary Liquid Mixtures Using Viscosity Data

Grunberg–Nissan parameter (d1) and the Gibbs free energy of activation of viscous flow (G*E) have been calculated with the help of density and viscosity data for sixteen binary systems at different temperatures and presented graphically. The system combinations of terpenoids + hexane, aliphatic alcohols (C1–C4) + nitromethane, polyethers + alcohol and N-methylacetamide + solvents such as 2-methoxy ethanol and water have been interpreted on the basis of molecular interaction study. Density and viscosity data necessary for calculation of above mentioned parameters for the binary mixtures are taken from literature. The results are discussed in terms of strength of interaction between the component molecules. The trend of graph is unique and leads to reliable conclusions.
