ABSTRACT:
A flow-through electrochemical cell for sequentially oxidizing and reducing an aryl compound. The cell includes a cell body forming a compartment to hold an aqueous electrolyte solution, a porous anodic electrode, and a porous cathodic electrode. The anodic electrode includes a first porous layer of a hydrophobic material, a second porous layer with an oxidation catalyst dispersed therein, and a current collector in electrical contact with the second layer. The cathodic electrode comprises a block of a porous, electrically-conductive material impregnated with lead particles. The cell is particularly useful for the preparation of aryl hydroquinones at very high current efficiencies, high current densities, and low voltages.
