colorless crystal or white crystalline powder. Melting point of 610 deg C, about 400 deg C decomposition; d 2. 52. Soluble in 65 parts of cold water, 15 parts of boiling water, insoluble in ethanol. Heat is decomposed into potassium chloride and oxygen. When potassium chloride, potassium bromide, potassium iodide, copper, iron and the like are present, the decomposition reaction is intensified. With strong oxidation. Risk of combustion explosion when contacted or mixed with organic matter, reducing agents, and combustible materials. Dry solid perchlorate can cause explosion upon impact and vibration.
sodium perchlorate was dissolved in water and the solution was filtered. Potassium chloride was additionally dissolved in water. The two solutions were mixed, and the potassium perchlorate crystals were filtered off by suction, washed off the adsorbed CI-, and dried to obtain pure potassium perchlorate.
Analytical reagents. It is used as the combustion improver of rocket and jet propeller, the oxygen supply agent of submarine, etc., and has been applied in the fields of explosives, photography, pharmaceutical industry, etc.
has strong irritation. High concentration exposure, serious damage to the mucosa, upper respiratory tract, eyes and skin. 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. Store in a cool, ventilated warehouse. Pay attention to moisture and rain. Should be stored separately from flammable, combustible materials, reducing agents, etc.
