FIELD: chemistry.
SUBSTANCE: invention relates to purification of gases from halogen-containing compounds. Claimed is hydrogen chloride absorber, containing 40.0-80.0% if zinc oxide, 2.0-10.0% of calcium oxide and aluminium oxide. Reaction mixture, containing zinc oxide, thermally activated aluminium hydroxide, aluminium hydroxide of pseudoboehmite structure and calcium carbonate is the source of zinc, calcium and aluminium oxides.
EFFECT: prevention of softening and destruction of absorber in the process of sorption over a long period of time.
