Correspondence between Grunberg-Nissan, Arrhenius and Jouyban-Acree parameters for viscosity of 1,4-dioxane + water binary mixtures from 293.15 K to 320.15 K

Abstract

The study of physical properties of binary liquid mixtures is of great importance for understanding and characterisation of molecular interactions. In the same way, some models attempt to correlate viscosity in liquid mixtures to release eventual interactions, structures' change and peculiar behaviours. Grunberg-Nissan (GN) parameters for viscosity () in 1,4-dioxane þ water mixtures over the entire range of mole fractions under atmospheric pressure and from 293.15 K to 320.15 K were calculated from experimental dynamic viscosities presented in previous works. Many experimenters investigate physicochemical properties using numerous models to derive some interpretations and conclusions. The present work comes within the framework of correlating different used equations to restrict investigations with an optimal of number of these models. Relationship between the GN, Arrhenius and Jouyban-Acree parameters for viscosity is shown in one binary mixture which dielectric constants of their pure components are very distinct.

“…In addition, the reduced R-K function relative to the viscosity Arrhenius activation energy which is equivalent to the apparent molar property gives more information because it is more sensitive than the excess property to interaction 22,23 .…”

Notion of viscosity Arrhenius temperature forN,N-dimethylacetamide withN,N-dimethylformamide binary mixtures and its pure components

“…So, the quasilinear behaviour shown in Figure 2 and the small difference between the quantities, Arrhenius activation energy E a (kJ·mol −1 ) and the logarithm of the entropic factor of Arrhenius −R·ln(As) of the two pure components well confirms the feeble interaction manifested previously (Table 1). In addition and similarly to Equation (6), the corresponding reduced Redlich-Kister excess quantities (Table 1) are in relationship with the GN interaction parameters [7][8][9] at desired temperature:…”

“…The quasi-linearity of the plotted curves in Figure 1 shows that the molecular interaction is weak and the mixture's nature is very much similar to the ideal solution. We can add that the Grunberg-Nissan (GN) parameter G 12 has small values where the binary liquid mixtures using GN model [9] could be determined by the Equation (3):…”
