colorless or white crystalline powder, tetragonal. d16 3. 865. 300 C decomposition, soluble in cold water, sulfuric acid, nitric acid and acetic acid, insoluble in concentrated sodium hydroxide solution and ethanol. Its aqueous solution is produced by hydrolysis of H and HIO ~-; And acidic.
chlorine oxidation method: the iodine is oxidized in an aqueous medium with chlorine gas to generate periodic acid. After separation, sodium hydroxide solution is added and neutralized to Ph 2-3 to generate Sodium periodate solution, after purification, separation of impurities, evaporation concentration, cooling crystallization, centrifugal separation, drying, prepared Sodium periodate product.
may be used as an oxidizing agent. For ceramic paper, printed cloth, printing paper screen printing process; In the printing plate manufacturing process, for the removal of insoluble polyvinyl alcohol layer from the printing plate bottom. It is also used in the food and pharmaceutical industries.
has a irritating effect on the skin and eyes, should prevent contact with the skin and eyes. Staff should be protected and the workplace should be well ventilated. If you accidentally touch the skin and eyes, you should immediately rinse with a lot of water, and in severe cases, you should see a doctor. Should be stored in a cool, ventilated, dry, light-protected warehouse. The container should be sealed away from organic matter and other easily oxidized articles. It is not allowed to be stored and mixed with flammable and explosive articles. The application of railway carriage or other covered transport. When there is a fire, it can be suppressed by sand and carbon dioxide fire.
