The reaction of 2.6 kPa propylene over preoxidized 20% silver on aerosil silica yielded only carbon dioxide, water, and a carbon-rich deposit, which could be oxidized to carbon dioxide and water. The carbon deposit presumably formed by polymerization of adsorbed acrolein species, which were observed in the IR spectra of the reaction of a 1:3 oxygen-propylene mixture over the same catalyst. In the presence of oxygen, a steady-state amount of the acrolein species apparently formed on the reoxidized silver, which underwent polymerization and subsequent oxidation. These surface processes explain the low selectivity for epoxide formation of propylene on silver catalyst.
