ABSTRACT:
The present invention relates to a method and electrochemical cell useful for the selective electrochemical oxidation of aryl-compounds including aromatic and polynuclear aromatic hydrocarbons such as benzene, naphthalene and anthracene or their derivatives such as phenols and naphthols. The anodic electrode of the cell includes a first foraminous or porous layer of a hydrophobic material; a second foraminous or porous layer which includes an oxidation catalyst; and an electrical current collector in contact with the second layer. As a result of the special chemical properties and porosity of the first and second layers of the anode, and because of careful control of the pressure differential between the electrolyte solution and the aryl-compound, an active interface is formed by the electrolyte solution and aryl-compound between the first and second layers or in the second layer of the anode thereby providing for very selective controlled oxidation of the aryl-compound with excellent current efficiencies.
