Mathematical Representation of Viscosity of Ionic Liquid plus Molecular Solvent Mixtures at Various Temperatures Using the Jouyban-Acree Model
چکیده
The viscosity of room temperature ionic liquid + molecular solvents is correlated using the Jouyban-Acree model, and the accuracy of the model is evaluated using average relative deviations (ARD) of the calculated and experimental values. The overall ARD of 6.9 % was obtained for the proposed model where the overall ARD for a similar model from the literature was 22.4 %. The mean difference between ARDs of the models was statistically significant: Combined forms of the Jouyban-Acree model and the Abraham parameters were used for predicting the viscosity of the mixtures at various temperatures. The overall ARD for the investigated mixtures was 15.0 % when the experimental viscosity of the pure solvents was included. The ARD of the in silico version of the model was 20.7 %.
