Seven new deep eutectic solvents based on tetrabutylammonium bromide and tetraethylammonium p-toluene sulfonate were prepared and their viscosity determined between 298.15 and 323.15 K. The effect of temperature was modeled using an appropriate fitting procedure, proposed in this work, with a coefficient of determination R2 > 0.99 for all DES. The fitting procedure used of pre-existing exptl. data in which 70 DESs were collected from the literature and refined on the basis of R2 and root mean square error (RMSE); ∼10% of the data was rejected. Furthermore, about half of the refined data was fitted with a three-parameter Vogel-Fulcher-Tammann (VFT) equation with an R2 higher than 0.99. The remaining data were more adequately fitted with a two-parameter Arrhenius equation. The adjusted parameters of both models for 62 DESs were determined to estimate the viscosity. Based on R2, the VFT model was more accurate than the Arrhenius model. Moreover, addnl. in-lab experiments were performed for model validation at six temperatures In some cases, the exptl. measurements were different from those in the literature with an R2 below 0.95 indicating a large scatter in the viscosity data. Most of the highly viscous DESs considered in this study showed a rapid decay when temperature increases. Hence, the limitation of using these solvents for applications such as absorption could be overcome by operating at slightly higher temperature (i.e., 313.15 to 333.15 K).
