Summary

Pyridine and its 2-methyl, 2,4-dimethyl and 2,4,6-trimethyl derivatives enhance the extraction of cobalt(II) into chloroform in the presence of 8-quinolinol and its 2-methyl, 4-methyl, 5-chloro and 5-nitro analogues. Adduct formation constants were determined for the cobalt(II) chelates, which formed diadducts with the pyridine bases. The special role of steric factors is discussed. The results are consistent with Lewis acid-base concepts.
