ABSTRACT OF THE DISCLOSURE A catalyst composition is provided having copper chloride deposited on a fluidizable alumina support in which the support has incorporated prior to deposit of copper from 0.5 to 3.05 by weight of at least one alkali metal, alkaline earth metal or rare earth metal. Such catalyst composition is used as the fluid bed catalyst in the vapor phase reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichlo- ethane. This results in improved yield and efficiency of EDC production based on ethylene and avoids operating problems caused by stickiness in the fluid bed. Incor- poration of a combination of potassium and barium in the fluidizable alumina support prior to deposit of copper produces an excellent catalyst for the fluid bed ethylene oxyhydrochlorination process in which the vent gases are recycled.
