PROCESS FOR REMOVING ORGANOCHLORINE COMPOUNDS FROM THE OFFGAS FROM THE OXIDATION OF ETHYLENE

Organic chlorine compounds are separated off from the waste gas formed in the reaction of ethylene with oxygen to give acetaldehyde in the presence of a catalyst system comprising palladium and copper or compounds thereof in a hydrochloric acid aqueous solution, by countercurrent washing of the wast...

Beschreibung
Zusammenfassung:	Organic chlorine compounds are separated off from the waste gas formed in the reaction of ethylene with oxygen to give acetaldehyde in the presence of a catalyst system comprising palladium and copper or compounds thereof in a hydrochloric acid aqueous solution, by countercurrent washing of the waste gas discharged after isolation of the reaction products at temperatures of 233 K to 323 K and pressures of 1 to 10 bar using polar organic solvents.
