ABSTRACT:
A process for producing chlorine by oxidizing hydrogen chloride with oxygen. The process uses various supported ruthenium catalysts or a catalyst system containing (A) an active component of a catalyst and (B) a compound having thermal conductivity of a solid phase measured by at least one point within a range from 200 to 500° C. of not less than 4 W/m. ° C.
