Abstract
The highly chlorinated methanes, e.g., carbon tetrachloride, are improvedly dechlorinated by reacting same with hydrogen in the presence of oxygen or an oxygen-containing gas, e.g., air, and a catalytically effective amount of a metal of the copper or precious metal Groups of the Periodic Table, typically in the form of a fixed or fluidized bed thereof, and advantageously in the gaseous phase.
