Brief review of the chemistry of polyphosphoric acid (PPA ...

The basic compounds for the production of polyphosphoric acid (PPA) are phosphorus pentoxide (P2O5) and phosphoric acid (H3PO4), as shown in Figure 2. Phosphorus is first oxidized to phosphorus pentoxide, which crystallizes as P4O10. Upon its reaction with water, phosphoric acid is produced. This route to H3PO4 is known as the dry process,
