Polyphosphoric Acid (PPA), Molecular formula: H6P4O13, is an inorganic chemical compound, having strong hygroscopic properties. Polyphosphoric Acid is an odorless, colorless, and highly viscous liquid compound. Polyphosphoric acid is a mixture of linear phosphoric acids and orthophosphoric acid. Polyphosphoric acid is formed by heating and dehydration of phosphoric acid followed by polycondensation process.
During this process, phosphoric acid forms chains and eliminate the water molecules. Also, Polyphosphoric acid can be produced by adding phosphorus pentoxide to water and then heating and condensing mixture to yield finish product. Polyphosphoric Acid is appeared as glass at low temperatures and becomes liquid/fluid when heated to 50 to 60 °C. Polyphosphoric Acid is easily deliquescent, miscible with water and hydrolyzed to phosphoric acid.
Moreover, the concentration of Polyphosphoric acid is represented by two methods, either it can be expressed as the concentration of P2O5 %, or in term of conc. of H3PO4 % i.e. the content of H3PO4 in Polyphosphoric acid. Polyphosphoric acid is weaker than sulfuric acid and nitric acid and has no oxidizing power.
In Industry, Polyphosphoric Acid is prevalently used as reagents in the synthesis of acid amides, acetylation, cyclic ketones & olefins, alkylation, and amines, among others. Also, Polyphosphoric Acid finds application as a catalyst in the petroleum and petrochemical for dehydration, polymerization, condensation, alkylation, and isomerization processes.
Moreover, Polyphosphoric acid has strong dehydration tendency with moderate acidity. Unlike sulphonic acid, polyphosphoric acid does not oxidize the reactants, and albeit its acidity is weaker than sulfonic acid, its dehydration tendency is equivalent to 100% sulfonic acid. Owing to which, it is used in the analytical studies.
