Effects of salts on the stability of the cationic radical of phenothiazine derivatives.
Effects of cations and anions of various salts on the stability of the diethazine cation radical were studied in various mineral acids. It was found that stability is enhanced in the presence of salts that contain the same anion as that contained in the cation radical salt. Other anions decrease the stability. The influence of salt cations is negligible.
