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.

Introduction	Sodium periodate is a white tetragonal crystal that dissolves in water and acid. Contains trace amounts of free acid, chloride, bromide, sulfate, heavy metals and other impurities. Purification can be performed by recrystallization from an aqueous solution. This kind of goods has a strong oxidation performance, although it does not burn, but under certain conditions, subject to friction, vibration impact, high heat or acid and alkali substances, in the damp, contact with organic matter, when the reducing agent and the articles that conflict with the nature are mixed, they can be decomposed, and combustion and explosion occur.
Application	Sodium periodate has two main uses in Organic Synthesis: it is used as an oxidant and a catalyst. Due to the solubility, the oxidation of Sodium periodate is generally carried out in water. Since many organic substances are insoluble in water, the use of co-solvents is desirable. The oxidation reaction can also be carried out in a two-phase system when a phase transfer catalyst is present or Sodium periodate is supported on an inert support.
solubility in water (g/100ml)	grams dissolved per 100ml of water at different temperatures (℃): 1.83g/0 ℃;5.6g/10 ℃;10.3g/20 ℃;19.9g/30 ℃;30.4g/40 ℃
toxicity	has a irritating effect on the skin and eyes and should prevent contact with the skin and eyes. If you accidentally splash on the skin, wash it off with soap water; If you splash in the eyes, immediately rinse 15 mln with a large amount of water and ask a doctor for treatment. Should pay attention to dust. Wear work clothes, latex gloves, closed protective glasses, masks and other protective equipment during operation. Production equipment should be closed, ventilation should be good.
Use	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. Sodium periodate can be used as an important raw material in the pharmaceutical industry, and can also be used as a common analytical reagent and chromatographic analysis reagent. used as pharmaceutical intermediates and health products quinone is produced by the cleavage of diols and the oxidation of hydroquinone.
production method	iodine is oxidized by chlorine gas in aqueous medium to form periodic acid, sodium periodate solution is generated by adding sodium hydroxide solution and neutralized to Ph 2~3, and then purified, separated impurities, concentrated by evaporation, cooled crystallization, centrifuged separation and dried to obtain Sodium periodate finished product, HIO4 NOH → NaIO4 H2O
category	oxidant
toxicity grade	high toxicity
Acute toxicity	intraperitoneal-mouse LD50: 58 mg/kg
explosive hazard characteristics	mixed with reductant, sulfur, phosphorus, etc, friction can burst
flammability hazard characteristics	toxic iodide and sodium oxide fumes from combustion
storage and transportation characteristics	The warehouse is ventilated and dried at low temperature; It is light and easy to discharge; It is combined with organic matter, reductant, sulfur and phosphorus combustible substances, separate storage of food raw materials
fire extinguishing agent	water, sand, foam
