description The invention relates to the technical field of inorganic chemistry, in particular to ahydrochloric acid decomposition method which comprises the following steps: mixing hydrochloric acid with the mass fraction of 20%-31% with anhydrous copper chloride at normal temperature for 6-60 min, and condensing an obtained gas at-30 to-10 DEG C to obtain hydrogen chloride gas. The hydrochloric acid decomposition methodprovided by the invention is simpler in process and higher in decompositionefficiency, and the obtained hydrogen chloride gas is higher in yield and purity. In addition, the hydrochloricacid decomposition method can prevent the equipment from being in a concentrated/dilute sulfuric acid, concentrated/dilutehydrochloric acid and the like high temperature dangerous liquid corrosive liquid environment; the whole process is completed between a solid state and a gas state, hydrogen chloride gas adsorbed on the surface of the solid is firstly removed in the drying regeneration processof the mixed copper chlori
