Abstract
The viscosities of binary mixtures of 1,4-butanediol with o-cresol, m-cresol and p-cresol were determined at 303.15, 308.15, 313.15 and
318.15 K over the entire mole fraction range. The deviation in viscosity, and excess Gibbs energy of activation (G*E) of viscous flow
were examined in terms of structural changes and interactions. The deviation/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.
