Abstract

The interaction of oxygen and ethylene glycol with the surface of several carriers and deposited silver catalysts was studied by programmed-temperature desorption and programmed-temperature reaction methods. Silver was shown to be present in a high-dispersity state on the surface of aluminosilicate carriers. A decrease in the selectivity of catalysts during glyoxal synthesis occurred because of an increase in the fraction of dissociatively adsorbed ethylene glycol responsible for the formation of formaldehyde and CO2. A decrease in the amount of oxygen adsorbed in the atomic form caused a decrease in the concentration of active centers capable of transforming ethylene glycol to glyoxal.
