A process for the preparation of monohalogenated ketone is described wherein the ketone is vaporized in a collection vessel, and the vapors are caused to pass upwardly through a defined reaction zone into a condensation zone where they are condensed and caused to flow downwardly into the reaction zone. In the reaction zone their flow toward the collection zone is retarded, and while retarded, halogen is directed thereagainst. The halogenated ketone so formed is removed into the collection zone such as by directing condensed non-halogenated ketone thereagainst.
