A process for the use of elemental chlorine, as a gas, in high temperature processes consists in circulating chlorine in a graphite reactor which has a double wall chamber. In the space defined by the double wall, a pressure of either nitrogen, argon or helium is maintained at a value high er than the pressure inside the reactor. In so doing, a radial diffusion of the gas within the wall towards the lower pressure zone inside the reactor is maintained through the graphite wall, thus sweeping to the inside of the reactor any chlorine that would otherwise diffuse radially outward and corrode rapidly the outer metallic shell of the reactor.
