Abstract
Authors report an exhaustive literature survey conducted
to collect an extensive set of liquid viscosity data for ionic liquids (ILs). They have collated a data set consisting of
1672 viscosity values and comprising 443 ILs from 204 different literature
sources.
Using the data set, they develop a reliable
group contribution method. The method employs a total of 46 sub-structures in
addition to the temperature to predict the viscosity of ILs.
