| Abstract: | A systematic study has been made of the influence on the nature and quantity of products formed by electro-oxidation with gold electrodes of aqueous solutions of ethylene, the pH, the potential applied to the electrode, the temperature and the rate of electrolysis.Details have been given, whatever the experimental conditions, of the formation of dosable quantities of acetaldehyde, glyoxal, glycolaldehyde, formaldehyde, acetic acid, oxalic acid and carbonic acid gas.Beginning with the distribution of these various products in correlation with the various parameters, a possible mechanism has been suggested for the electro-oxidation of ethylene with gold electrodes, with the formation on the electrode of a species of activated or protonized acetaldehyde. |
