colorless, transparent, shiny crystals or white particles or powders. Melting point 368 C; d 2.32. 19 The product can be slowly dissolved in 16.5ml water, 1.8mL boiling water, about 50mL glycerol, almost insoluble in ethanol. Its aqueous solution is neutral. Decomposition begins at about 400 °c and all oxygen is released at 610 °c. In the presence of the catalyst (manganese dioxide), oxygen is evolved by decomposition at a lower temperature. With strong oxidation. Risk of combustion explosion when contacted or mixed with organic matter, reducing agents, and combustible materials. Explosion can occur when heated sharply.
The sodium chlorate solution was allowed to react with a certain amount of potassium chloride, and the resulting solution was cooled and crystallized to obtain a crude product. Then, the obtained crude product is dissolved in water, subjected to recrystallization purification, filtration, cooling, Suction filtration to remove crystals, washed with a small amount of cold water, and then dried.
Analytical reagents for the determination of manganese, sulfur, nickel, copper, iron sulfide. Also used as oxidant, oxygen raw materials, explosive raw materials.
is a blood poison, manifested as methemoglobinemia, gastroenteritis, liver and kidney damage, and even asphyxia. Dust is irritating to the respiratory tract. The lethal dose to humans is about 109. Staff should be well protected, if accidentally touch the eyes, should immediately rinse with a large amount of flowing water. The working environment should have good ventilation conditions. It should be stored separately from flammable and combustible materials, reducing agents, metal powder, sulfuric acid, etc., and should not be mixed, stored and transported.
