Polyphosphoric acid Chemical Properties,Uses,Production

Description

Superphosphoric acid is made by the concentration of regular wet-process acid up to P2O5 concentrations of 78%. Granular polyphosphates suitable for bulk blending are made by reacting ammonia with regular wet process acid of 52% P2O5 content and using the heat of reaction to drive off water to produce a phosphate melt of 10-43-0, with about 40% of the phosphorus in the polyphosphate form. These materials are, however, not suitable for bulk blending due to their “sticky” nature (10).

Chemical Properties

Viscous, water-white liquid. Water solu- ble. Does not crystallize on standing; hygroscopic. The commercial acid is a mixture of orthophos- phoric acid with pyrophosphoric, triphosphoric, and higher acids and is sold on the basis of its calcu- lated content of H3PO4, e.g., 115%. Superphospho- ric acid is a similar mixture sold at 105% H3PO4. These acids revert slowly to orthophosphoric acid on dilution with water.

Uses

Dehydrating, catalytic, and sequestering agents, for metal treating; many applications where a con- centrated monooxidizing acid is needed; laboratory reagent.

Definition

ChEBI: A polymerized phosphorus oxoacid of general formula HO[PO2OH]nH formed by condensation of orthophosphoric acid molecules and containing a backbone chain consisting of alternating P and O atoms covalent y bonded together.

Hazard

Toxic by ingestion; strong irritant.

Agricultural Uses

Polyphosphoric acid is obtained by heating the wetprocess phosphoric acid. It contains around 72% phosphorus (as P2O5) and represents a series of phosphoric acids containing more than one atom of phosphorus (such as H4P2O7). The general formula is Hn+2PnO3n+1.
