Abstract
The effect of various substituents in pyridine derivatives upon the basicity of the nitrogen was discussed. The dissociation constants were correlated with the Hammett parameters and compared with copper extraction data. The analysis of nitrogen basicity in pyridine derivatives permits to select possible structures of extractants for metal extraction from chloride solutions.
