Chronopotentiometry and coulometric titration of n-substituted phenothiazines
The electrochemical oxidation at a platinum anode of several N-substituted phenothiazines (levopromazine, chlorpromazine, multergan, profenamine, promethazine, diethazine, and thioproperazine) has been studied by the chronopotentiometric technique. A method has been developed for the coulometric tit...

description | The electrochemical oxidation at a platinum anode of several N-substituted phenothiazines (levopromazine, chlorpromazine, multergan, profenamine, promethazine, diethazine, and thioproperazine) has been studied by the chronopotentiometric technique. A method has been developed for the coulometric titration of these substances with electrogenerated cerium (IV). Quantities of 0.25–20 mg are determinable with an average error of less than ± 1 rel. %.
Les propriétés électrochimiques de diverses phénothiazines substituées à l'azote (lévopromazine, chloropromazine, multergan, profenamine, prométhazine, diéthazine, et thiopropérazine) sont examinées par chronopotentiometrie. La titration coulométrique de ces constituants est développée à l'aide de l'ion cérique electrogénéré sur des quantités comprises entre 0.25 et 20 mg avec une bonne précision (±1% d'erreur relative).
Es wurde chronopotentiometrisch die elektrochemische Oxydation von N-substituierten Phenothiazinen untersucht. Dabei wurde eine Methode zur coulometrischen Titration dieser Substanzen mit elektroerzeugten Cer(IV)-Ionen entwickelt. Mengen von etwa 0.25 bis 20 mg sind mit einem durchschnittlichen Fehler von weniger als± 1% zu bestimmen. |
