Storage conditions

Precautions for storage Store in a cool, ventilated warehouse. Keep away from fire and heat. The storage temperature does not exceed 30 ° C and the relative humidity does not exceed 80%. Packaging sealed. It should be stored separately from flammable substances, alkalis and active metal powders, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

Stability

1. Deliquescent. Its acidity is weaker than strong acids such as sulfuric acid, hydrochloric acid and nitric acid, but stronger than weak acids such as acetic acid and boric acid. It will lose water to pyrophosphoric acid after being heated to about 200 ℃ at high temperature. Corrosive. Decomposition by heat produces highly toxic phosphorous oxide fumes. Contact with strong corrosives gives off a lot of heat and sputtering occurs.

2. Stability

3. Incompatible materials Strong alkali, active metal powder, flammable or combustible

4. Conditions to avoid contact with heat, humid air

5. Polymerization hazards

6. Decomposition products Phosphorus oxide

Water solubility MISCIBLE
