liquid | [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. | [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). | [General Description]
Polyphosphoric acid (PPA) is widely employed as acylation and alkylation reagent in various reactions. It is a strong mineral acid with excellent dehydrating properties. | [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. | [Solubility in water]
Polyphosphoric acids are miscible with water, hydrolyzing to orthophosphoric acid with the generation of heat. They are insoluble in hydrocarbons and halogenated hydrocarbons. |
