Desorption of an intermediate in the complete oxidation of C2H4 over silver catalyst

Abstract
It was found by applying the transient response method that a stable intermediate was formed during the complete oxidation of C2H4 over a silver catalyst which could be desorbed as acetic acid in a stream of pure H2, whereas it was not desorbed in pure He and it was decomposed to CO2 and H2O in a mixture of O2–He.
