A PROCESS FOR THE CATALYTIC VAPOUR-PHASE OXIDATION OF ETHYLENE WITH A MOLECULAR OXYGEN-CONTAINING GAS, IN A SINGLE-COMPARTMENT REACTOR (A) COMPRISING A MULTITUDE OF REACTION TUBES CONTAINING A SUPPORTED SILVER CATALYST AND SURROUNDED BY A HEAT-EXCHANGE FLUID WHICH ENTERS THE REACTOR (A) IN LIQUID FORM AND LEAVES THE REACTOR (A) IN VAPOUR FORM, CHARACTERIZED IN THAT BETWEEN 5 AND 100 WT% OF THE LIQUID HEAT-EXCHANGE FLUID IS INTRODUCED TO THE REACTOR (A) AND ITS DOWNSTREAM END, AT A TEMPERATURE WHICH IS AT LEAST 20°C BELOW THE TEMPERATURE OF THE HEAT-EXCHANGE FLUID ON LEAVING THE REACTOR (A).
