CARDONA-PALACIO, Luis-Fernando. Simple and Generalized Model to Estimate the Thermal Conductivity of Ionic Liquids. Rev. Cient. [online]. 2021, n.42, pp.276-289.  Epub Oct 18, 2021. ISSN 0124-2253.  https://doi.org/10.14483/23448350.18052.

In this work, an empirical model is generalized to predict the thermal conductivity of ionic liquids. Initially, experimental data are collected, which include different types of anions and cations. A total of 38 ionic liquids are evaluated (28 substances for correlation and 10 substances for prediction), which corresponds to 265 experimental data. The temperature ranges vary between 273 and 390 K at atmospheric pressure (1 atm). The model is generalized using 215 experimental data, and the average deviation is around 4.72%. Then, the predictive capabilities are evaluated in 50 experimental data with an average deviation of 3.48%. The generalized model is extended to binary mixtures using a simple mixing rule with an interaction parameter, and the absolute deviation is 0.77%. Finally, the generalized model is compared with others developed in the literature, and the statistical analysis shows that it provides acceptable results.
