FIELD: chemistry.
SUBSTANCE: present invention relates to a catalyst for gas-phase oxidation of hydrogen chloride to obtain chloride. Described is a catalyst for oxidation of hydrogen chloride, which contains uranium oxide as a catalytically active component and a support, wherein the support itself is a catalytically active component and the catalyst is pretreated with a stoichiometric mixture of HCl and oxygen at temperature of at least 400°C for at least 10 hours. Described is use of said catalyst in gas-phase catalytic oxidation of hydrogen chloride with oxygen and a method of producing chlorine using the catalyst.
EFFECT: catalyst is distinguished by high stability and activity.
