ELECTROCHEMICAL PRODUCTION OF CYCLOHEXANOL OR ITS ESTER

摘要

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.
