| Abstract: | The empirical diluent parameters DP, introduced by Shmidt et al. several years ago, describe the extraction of mineral acids or metal complexes by the expression log Kex = log Kex ° + const. DP. They have now been related to independently obtainable properties of the diluents. The best correlation is with Dimroth and Reichardt's polarity index ET, with Hildebrand's solubility parameter δ as an additional parameter causing some improvement. The new expression is: log Kex = log Kex ° + const1. ET + const2. δ. |
