Stability and reactivity


Stability Although it is stable in the dry state, if it is wet or dissolved in water, It generates hypochlorous acid.


Heating / combustion There is a danger.
It decomposes to produce chlorine, carbon monoxide, nitrogen trichlorideGenerate toxic gas.
Water There is a danger.
It hydrolyzes to generate hypochlorous acid. When reacting with a small amount of water, reaction heat accumulates, there is a danger of fire or toxic gas generation.
Air No risk
Incompatible There is a danger.
It decomposes when mixed with acid, alkali, reducing substances, fats and oils, other oxidizing agent (bleaching powder, sodium hypochlorite) or the like, it generates toxic gases such as chlorine, carbon monoxide and nitrogen trichloride.
There is a danger of explosion as the concentration of nitrogen trichloride increases.
Conditions to Avoid Mixed contact with other substances and heat and humidity
Hazardous decomposition products Chlorine, carbon monoxide, nitrogen trichloride etc.
Incompatible hazardous substance Flammable substances and reducing substances.
Ammonia, ammonium salts and amines, sodium carbonate (soda ash)

Handling and Storage Precautions


Technical measures Reduce gas divergence as much as possible, and use protective gear, protective eyeglasses, rubber gloves, dust mask etc.
Install a local exhaust system.
Notes Handle the container carefully, scatter it or waste liquid into a special container. Collect it.
Safety Handling Precautions Fire, heat, alkalis, organic solvents, reducing substances and other combustible substances. Avoid contact.
Contact with advanced bleaching powder, ammonia and its salts is an explosive. There is a danger.


Proper storage condition Isolate from those described in "Safety Handling Precautions", seal it in a cold-drying place store. Storage under nitrogen gas is desirable.
Safe containers and packaging materia Poly container, glass, pottery etc. (Metals are corroded)
EU risk phrase (R) 8-22-31-36/37
