Structure‐based model for prediction of electrical conductivity of pure ionic liquids

A structure‐based method was proposed to estimate the electrical conductivity of ionic liquids covering wide ranges of temperature (238.15–484.1 K) and electrical conductivity (0.0001524–19.3 S/m) based on experimental data collect from literature from 1998 to 2015. The influences of temperature and ion structure on electrical conductivity were also discussed. The mean absolute percentage error between the calculated and literature data was 6.02%, with 6.12% for the training set (1978 data points, 177 ILs) and 5.10% for the test set (217 data points, 11 ILs). © 2016 American Institute of Chemical Engineers AIChE J , 62: 3751–3762, 2016
