Abstract
Hydrocarbons, e.g., ethylene, are steady-state catalytically oxychlorinated into chlorocarbons, e.g., 1,2-dichloroethane, by fluidizing a fluidizable charge by directing a gaseous feedstream containing a hydrocarbon therethrough and therein oxychlorinating such hydrocarbon, the gaseous feedstream further comprising an oxygen-containing gas and gaseous hydrochloric acid and the fluidizable charge comprising immixture of a catalytically effective amount of an oxychlorination catalyst and particles of a catalytically and chemically inert solid substance, and which further comprises introducing a solution or suspension of a catalytically active copper compound into such fluidized charge during the oxychlorination reaction.
