Polyphosphoric Acid (PPA) is colorless transparent viscous liquid, hygroscopic, non -crystallizable, corrosive, water soluble into orthophosphate acid. Acidity is weaker than nitric acid and sulfuric acid. Non-oxidicability, could cause burns when meeting H vesicant. Specific gravity is 2.1g/cm3. Normal boiling point is 856ºC, keeping hard glassy block upon lowtemperature and liquid when heating up to 50~60ºC. Relative density is 1.987(P2O5 80.0%); 2.052(P2O5 84.0%); 2.084(P2O5 86.0%). Hazard label 20 (corrosives acidic properties). High viscidity, hard to stir or pour under normal temperature, and easily to operate when temperature is above 60ºC, omit heat when solublein water, should be under ice-bath station when making dilution.

A concentrated solution of phosphoric acid is irritating to the skin and eyes and can corrode the skin to cause inflammation. Phosphoric acid vapor can cause nasal mucosa atrophy, can cause systemic poisoning. The maximum allowable concentration of phosphoric acid in air is 1 mg/ma. If not, the skin contact with phosphoric acid, should immediately rinse with plenty of water, and wipe red mercury solution or gentian violet solution, poisoning phenomenon should be sent to the hospital immediately. It is not allowed to be stored and mixed with alkaline, toxic and corrosive substances.
