Correspondence Between Grunberg–Nissan, Arrhenius and Jouyban–Acree Parameters for Viscosity of Isobutyric Acid + Water Binary Mixtures from 302.15 to 313.15 K

Abstract

The study of physical properties of binary liquid mixtures is of great importance for understanding and characterizing intermolecular interactions. Similarly, some models attempt to correlate viscosity in liquid mixtures in order to illuminate interacting structures and peculiar behaviors. Grunberg–Nissan parameters for viscosity (η) in isobutyric acid + water mixtures over the entire range of mole fractions under atmospheric pressure and from 302.15 to 313.15 K were calculated from experimental dynamic viscosities presented in previous works. Many experimenters investigate physicochemical properties using various models to develop interpretations and conclusions. The present work comes within the framework of correlating different equations. Relationships between the Grunberg–Nissan and Arrhenius and Jouyban–Acree parameters for viscosity are shown in one critical binary mixture.
