ABSTRACT:
Substantially all of the chlorine values, e.g., chlorine, are recovered from reactant feeds of chlorinated organic compounds, e.g., hexachlorobenzene and hexachlorobutadiene, by an improved process involving catalytic oxidation at temperatures below 500.degree. C and more typically below about 450.degree. C using a catalyst of a chromium salt or oxide impregnated on a support.
