Catalysts and Methods for Oxyclolation of Ethylene with Ethylene Dichloride (EDC)

摘要

The present invention relates to a catalyst composition for oxcyclolining ethylene with 1,2-dichloroethane. The catalyst may be formed of copper chloride, at least one alkali metal, at least one rare earth metal and at least one Group IIA metal on a high surface area carrier when applied in a fluidized bed or on a carrier of high or low surface area when applied in a fixed bed. It includes. The catalyst composition is prepared by supporting a metal on a carrier. In the process of ethylene cyclooctalation with EDC, by using the catalyst composition according to the present invention, high ethylene efficiency, high EDC production purity and high HCl conversion can be obtained without agglomeration of the catalyst. In addition, the present invention describes an oxycrolination process of ethylene to produce 1,2-dichloroethane. The process includes contacting an oxygen mixture comprising ethylene, oxygen or gas and hydrogen chloride with a fixed or flow catalyst composition in the reaction zone, and withdrawing 1,2-dichloroethane from the reaction zone.
