Abstract
Nonaqueous titration and a study of IR and UV spectra has enabled us to elucidate and interpret the peculiarities in the properties of pyridinecarboxylic acids which form 2, 3-substituted derivatives of pyridine. The specificity of the structure of these acids determines the peculiarity of their chemical properties: stability to the action of ozone, but exceptional ease of decarboxylation in solvents capable of disturbing the conjugated system of bonds in these acids.
