The deviation in viscosity,, and excess Gibbs energy of activation (G*E) of viscous flow have been examined in terms of structural changes and interactions. The deviations/excess values were fitted to the Redlich-Kister equation to determine the fitting parameters and the root-mean square deviations. The results obtained for viscosity of binary mixtures were used to test the semi-empirical relations of Bingham, Frenkel, Kendall, HindUbbelhode, Refutas, Sutherland Wassiljiewa, Gambill, McAllister, Hind, Grunberg, Wijk, McAllister 4 body, Tamura Kurata, Katti-Chaudhri and Nhaesi. %U https://www.physchemres.org/article_132917_8889b44b2496c808eba7feb4b780d771.pdf
