Sodium Chlorate - Nature

Open Data Verified Data

white powder. Melting point 248 °c (decomposition). The solubility in water is 790g/L at 0 ℃, which is soluble in ethanol and ethylene glycol. It is easy to decompose and release oxygen when heated to above 300 ℃. In neutral or weak alkaline solution, the oxidation ability is low, but in acidic solution or in the presence of induced oxidant and catalyst, it is a strong oxidant. The action with acids releases chlorine dioxide. Mixing with sulfur, phosphorus and organic matter or being impacted is susceptible to combustion and explosion. Corrosive to zinc and carbon steel. Deliquescence, high humidity in the air can absorb water vapor solution.

It can be obtained by electrolysis of a concentrated acid solution of sodium chloride at 80 to 90 °c.

Sodium Chlorate - Use

Sodium chlorate is a white crystalline powder that has many uses in industry, including but not limited to the following:

1. Synthetic bleach: Sodium chlorate can be used as a raw material for synthetic bleach. Mixing sodium chlorate with an acid produces a very concentrated chlorine dioxide solution that is used for pulp, fabric, fiber and food bleaching.

2. Sodium chlorate can be used as an active ingredient of non-selective herbicides in herbicides. It has strong oxidizing properties and can destroy the structure and function of plant cells, resulting in plant death. Its mechanism of action is to cut off the oxygen supply in plants and accumulate harmful free radicals, causing the plants to suffer severe oxidative damage and die. Sodium chlorate herbicide can be used in farmland weeding, orchard weeding, woodland weed management and other fields. But at the same time, it is also necessary to pay attention to the safety and environmental protection when using it.

3. Sodium chlorate acts as an oxidizing agent during the synthesis of dye intermediates. Some organic substances can be oxidized under the oxidation conditions of sodium chlorate to generate target dye intermediates. At the same time, sodium chlorate can also be used as a decolorizer and bleaching agent in the dye synthesis process to remove or weaken the color of the dye.

4. Sodium chlorate is often used as an oxidant in metal smelting, which can help improve smelting efficiency and metal yield.

1) Raw copper smelting: Sodium chlorate can be used as an oxidant for copper ore, converting sulfur dioxide into sulfur trioxide, and then forming soluble copper sulfate.

2) Gold and silver smelting: Sodium chlorate can be used as an extractant for gold and silver, and it can be extracted from ores by forming complexes with gold and silver ions.

3) Cobalt and nickel smelting: Sodium chlorate can be used as an oxidant in cobalt and nickel smelting to convert sulfur dioxide into sulfur trioxide, and then react with sodium hydroxide to form soluble cobalt sulfate and nickel sulfate.

4) Smelting of tin, tungsten and molybdenum: Sodium chlorate can be used as a leaching agent for metals such as tin, tungsten and molybdenum, and form soluble compounds such as tin chlorate, tungsten chlorate and molybdenum chlorate with these metals. These metals are extracted.

5) Rare earth element smelting: Sodium chlorate can be used as a solvent for certain rare earth elements to extract them from ores for the production of rare earth permanent magnet materials, energy storage materials, catalysts and optical materials.

Sodium Chlorate - Safety

Open Data Verified Data

Acute Oral LDso in rats: 1.2g/kg; LDso in human: 15-20g/kg. Dust can irritate the skin, mucous membranes and eyes. Staff should be protected. If sodium chlorate is accidentally sprayed into the eyes or on the skin, it should be immediately rinsed with plenty of water. The workshop should be well ventilated.
