Abstract: Bipolar electrodes having two chambers for inflow and outflow of the reaction mixture to be electrolyzed. The chambers are separated from each other by a distance which is considerably larger than their width and the inlets and outlets are on the same side of the electrode. Electrodes of this kind are suitable, for example, for the Kolbe synthesis of dicarboxylic esters from dicarboxylic half-esters. Such esters are useful as plasticizers.
