Geometric similitude concept and Redlich-Kwong equation of state to predict thermal conductivity of choline chloride class of deep eutectic solvent

Thermal conductivity of 77 choline chloride-based deep eutectic solvents (DESs) has been estimated at 1.01325 bar and 298.15-333.15 K temperature range in the framework of geometric similitude concept incorporated in the Redlich-Kwong equation of state. The dataset consists of the choline chloride class of hydrogen bond acceptor and alcohol, organic acid, carbohydrate, amide-based hydrogen bond donors of which 17 DESs are used to estimate the model parameters in the Genetic Algorithm paradigm with a root mean square deviation of 4.37%. A priori estimation of thermal conductivity is further reported for the remaining 60 DESs over the same temperature range, and the framework is established as a theoretical framework for estimating the thermal conductivity of DES.
