Toxicity | LD50 orally in rats: 1.09 g/kg (Smyth) |
A dark purple or bronze-like crystal with metallic luster. Tasteless. About 240 °c decomposition; D2.7. Stable in air. Soluble in lye, soluble in 14.2 parts of cold water, 3.5 parts of boiling water. It is easy to fade in case of reducing agent. When alcohol, organic solvent or concentrated acid is decomposed to produce free oxygen. Chlorine gas was released in case of hydrochloric acid. With strong oxidation. Risk of combustion explosion when contacted or mixed with organic matter, reducing agents, and combustible materials. When glycerol was encountered, it was decomposed immediately and burned strongly. Can be decomposed by most reducing substances.
The crude potassium permanganate dissolved in hot water, after filtration, cooling, Suction filtration crystallization, drying, you can.
Analysis of reagents, drop analysis of barium, silver, sulfate, iron, vanadium and tin, clinical exfoliative cell testing. Oxidation Reduction Method for the determination of reagents and for emission spectrometry.
rat oral LDso:1.09g/kg. Inhalation can cause respiratory tract damage. Splatters within the eyes, irritation of the conjunctiva, severe cases cause burns. Irritation of the skin, concentrated solution or crystals are corrosive to the 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. Keep away from fire and heat source. Pay attention to moisture and rain. Keep the container sealed. Should be stored separately from flammable, combustible materials, reducing agents, etc.
