Abstract
The catalytic activity of metallic silver supported on zirconium phosphate has been examined in the reaction of ethylene oxidation in terms of the average silver particle size, the surface area of the support, and the cations present in the support. The activity was found to decrease when the surface area of the support was increased. A maximum activity and selectivity was obtained with silver particles about 480 Å in average diameter supported on highly crystalline zirconium phosphate. Cations present in the ion-exchange sites of the support have a strong effect on the catalytic properties. Among the cations used, Na+ gives the highest total conversion, K+ gives the best selectivity for ethylene oxide formation, while Cs+ was found to suppress the reaction completely. © 1985.
