Systematic Study on the Viscosity of Ionic Liquids: Measurement and Prediction
Dynamic viscosity for twenty-seven ionic liquids involving ions with molecular structures selected to infer the effects of molecular structure on fluids' viscosity is reported in this work as a function of temperature. The viscosity data are analyzed considering these structural features and fitted according to Vogel-Fulcher-Tamman equation. Viscosity data were systematically analyzed to infer anion and cation effects on the property. COSMO-RS method was used to infer relationships between molecular level features and viscosity data for the considered families of ions. A Quantitative-Structure-Property-Relationship model was developed using a Genetic Function approximation from selected molecular descriptors.
