SODIUM HYDROGEN PERIODATE - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| application | trisodium periodate is a strong oxidant, which can be used in laboratory research and development and chemical production. |
| production method | under alkaline conditions, it is produced with sodium iodide oxidized with bromine. In a 2L glass with mechanical stirring, 25gNaI and 132gNaOH were dissolved in 1L of water. Heat the solution to 80 ℃, slowly add 40mL bromine (under negative pressure) through the dropping funnel, and immerse the end of the dropping funnel in the liquid. Dropping acceleration 2 mL/min. The reaction temperature should be controlled at 80 ℃ as accurately as possible. After 25~40min, a large amount of salt precipitation will suddenly precipitate. If the reaction liquid vibrates strongly when heated, pour the liquid from the precipitate into another cup and continue to drip bromine. The precipitated Na3H2IO6 was filtered by suction and washed with distilled water for 4 times, 20~25mL each time. During washing, the crystals must be soaked in a funnel for 15min, and then filtered by suction. Finally, the crystal dries in the air. |
