ELECTROCHEMICAL REGENERATION OF CE(IV) FOR OXIDATION OF P-METHOXYTOLUENE

The development of the electrochemical oxidation of aromatic compounds on an industrial scale is hindered by the deactivation of the electro de occurring under anodic polarization. This paper presents some resul ts on the indirect oxidation of p-methoxy toluene by eerie sulfate ele ctrochemically regenerated on a platinized titanium electrode. A techn ique that reactivates the fouled electrode on the one hand and avoids the passivation of the electrode during electrolysis on the other hand is proposed. Methylene chloride is used to extract the organic produc ts from the aqueous phase before electrolysis. The preparative electro lysis of anisaldehyde is performed on the laboratory scale and the res ults show an overall (chemical and electrochemical) yield close to 80% .
