Abstract
The solubility of alkylpyridinium halides and their interionic charge transfer absorption bands (CT bands) were measured in eight nonaqueous solvents. The influence of counterion on the solubility was also studied. The examination of the CT bands showed that dodecylpyridinium halides dissociate in polar solvents, form ion-pairs in medium polar solvents and probably dissolve as neutral molecules in nonpolar solvents.
