PROCESS FOR THE PRODUCTION OF ETHYLENE OXIDE

摘要

23 H.31664 Process for the production of Ethylene Oxide Ethylene is oxidised to ethylene oxide over a silver containing catalyst which is promoted by high concentrations of potassium, rubidium or cesium, in the presence of a chlorine containing reaction inhibitor and at least 5,000 moles of ethane per mole of inhibitor expressed as its vinyl chloride equivalent. Permanent absorption of chlorine onto the catalyst (which leads to catalyst decay) is low in this process.
