Abstract: PURPOSE:To obtain a reaction product which does not contain molecular oxygen at a high reaction rate by bringing the oxygen permeated through a solid electrolyte substrate and the reaction substrate into reaction with each other with the prescribed laminated film disposed with electrodes on both faces of said substrate as a diaphragm. CONSTITUTION:The laminated film 2 constituted by forming metallic electrode films on both faces of the solid electrolyte substrate and laminating a homogeneous catalyst film on one face thereof is prepd. Two block chambers (a), (b) are formed of such film 12 as the diaphragm. The reaction substrate is supplied into the chamber (a) facing the homogeneous catalyst film and oxygen is supplied into the other chamber (b). A voltage is impressed between said metallic electrode films form a power source 10. The activity of the homogeneous catalyst film is improved by the oxygen permeated through the above-mentioned solid electrolyte substrate and the oxygen is brought into reaction with the reaction substrate. The reaction product which does not contain the molecular oxygen is thus obtd.

Abstract: PURPOSE:To electrochemically produce cyclohexanol or an ester thereof at a high conversion rate by adding a supporting electrolyte to a soln. of cyclohexane in a fatty acid and electrolyzing the resulting electrolytic soln. CONSTITUTION:Cyclohexane is dissolved in a fatty acid such as acetic acid and a supporting electrolyte consisting essentially of sulfuric acid and water is added. The resulting electrolytic soln. is electrolyzed at about 1.5-2.6V anode potential basing on the potential of a satd. calomel electrode. By the electrolysis, the cyclohexane is electrochemically oxidized on the surface of the anode to produce cyclohexanol. This cyclohexanol bonds nonelectrochemically to the fatty acid as a solvent, producing cyclohexyl ester.
