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.
Abstract translation: 双极电极具有两个用于待电解的反应混合物的流入和流出室。 这些室彼此分开一个远大于其宽度的距离，并且入口和出口位于电极的同一侧。 这种电极例如适用于从二羧酸半酯合成二羧酸酯的科尔贝。 这些酯可用作增塑剂。
