Properties prediction of ILs by RVA

The Residual Volume Approach provides a very simple, fast, and successful access to the prediction of density, viscosity,[1,3] ionic conductivity [2] and surface tension of pure Ionic Liquids. It accurately predicts the above mentioned properties by simple linear correlations between given property and the substituent constants βx. The corresponding substituent constants were defined for unbranched alkyl substituents from methyl to dodecyl. (details see Ref.1)

For accurate prediction of desired property the experimental data for at least three members of given series should be available. The series should differ only by one alkyl substituent at definite position.

How to predict properties by means of RVA?

  1. Select the property of interest from the top menu
  2. Fill the experimental data in the gaps corresponding to the substituents
  3. Press Enter or button Proceed
  4. In the right column the predicted values appear.
