SILVER-DEPOSITED CATALYST FOR PRODUCTION OF ETHYLENE OXIDE |
摘要 |
A silver-deposited catalyst for the production of ethylene oxide by the oxidation of ethylene, said catalyst comprising (1) a carrier composed mainly of alpha-alumina, which carrier does not show acidity in a visual color change method in a toluene solvent using a dimethyl yellow indicator having a pKa of +3.3, and does not show basicity in a color reaction in a toluene solvent using a bromothymol blue having a pKa of +7.1, and (2) as catalyst components, silver and at least one cationic component selected from sodium, potassium, rubidium and cesium. |
