Abstract
There is disclosed a method of recovering chlorine gas from calcium chloride comprising the steps of introducing calcium chloride into a heat-resistant vessel which is provided with a gas inlet pipe and a gas outlet pipe, heating the calcium chloride up to at least the melting point thereof while introducing an inert gas from the gas inlet pipe into the vessel to produce fused salt of calcium chloride, and heating the interior of the vessel up to at least 1073K and switching a gas to be introduced from the gas inlet pipe from the inert gas to oxygen to allow the fused salt of calcium chloride to react with the oxygen to obtain chlorine gas and calcium oxide, the chlorine gas being subsequently rapidly and continuously discharged from the vessel through the gas outlet pipe.
