Electrolytic Oxidation of Ethyl Alcohol to Acetic Acid
The influence of current density, ethanol concentration, and current concentration on the oxidation of ethanol to acetic acid in dilute sulfuric acid solution at platinum gauze anodes has been investigated. The maximum current efficiency, 85%, was obtained at 40° C and 0.2 amp./cm.2, the highest current density tried. Optimum alcohol concentration is about 20%. Efficiency can be raised 2% to 3% by the use of an oxygen carrier, and, at the same current density, is higher at higher current concentration, no maximum being found for this relation within the limits studied. Upwards of 5% increase in efficiency was obtained by substituting sheet lead for platinum gauze as anode material. Energy consumption ranged from 9.9 to 13.8 kw.‐hr./kg. acetic acid, depending on conditions of operation and cell design.
