摘要： PURPOSE:To manufacture Na2S2O4 of high purity at an improved current efficiency, by circulating hydrochloric acid soln. through an anodic chamber separated by a cation exchange membrane while feeding hydrochloric acid to the anodic chamber, and by electrolyzing aqueous sodium hydrogensulfite soln. made by supplying SO2 to the sodium sulfite soln. in the cathodic chamber. CONSTITUTION:Aqueous hydrochloric acid soln. is circulated through the anodic chamber of an electrolytic cell having the anodic chamber separated from the cathodic chamber with a cation exchange membrane while charging hydrochloric acid soln. to the anodic chamber. On the other hand, sulfurous acid gas is supplied to the soln. contg. sodium sulfite in the cathodic chamber to form aqueous sodium hydrogensulfite which is electrolyzed thereby manufacturing catholyte contg. Na2S2O4. Na2S2 O4.2H2O is crystallized by addition of sodium sulfite to the catholyte. To the soln. separated from the Na2S2O4.H2O is added sulfurous acid gas to form sodium hydrogensulfite, which is led to the cathodic chamber and is used for manufacturing Na2S2O4. This method allows to manufacture Na2S2O4 of high purity at about 95% current efficiency.
