Récents développements des procédés d'électrosynthèse organique


Laboratoire de Génie Chimique et Electrochimie, URA 192 du CNRS, Université Paul Sabatier, 118 Route de Narbonne, 31062 Toulouse, France

Recent developments of some electro-organic processes of industrial interest studied in France are presented. They are illustrated by examples of syntheses conducted by classical oxidation or reduction of chemical functions. Special attention is payed to the use of cathodes activated in situ by a zinc layer and their application in the electrosyntheses of chlorotrifluoroethylene and amino-alcohols. New reactors with porous electrodes are particularly suitable for the syntheses of a certain number of nitroso-compounds. Electrochemical processes involving the use of sacrificial anodes of magnesium, or aluminum, which are interesting in functionalization of organic halides, were particularly developed in France these 10 last years. Examples concerning the build-up of new materials such as doped polymers, or some organosilanes used as ceramic precursors are also presented. Some of the above cases constitute favorable occasions to discuss innovations in electrochemical reactor technology.
