Phosphoric acid decomposition
The simplest and most commonly encountered of the phosphoric acids is orthophosphoric acid, H3PO4. Indeed, the term phosphoric acid often means this compound specifically (and this is also the current IUPAC nomenclature). Two or more orthophosphoric acid molecules can be joined by condensation into larger molecules by elimination of water. Condensation of a few units yields th… WebThe presence of HPO shifted the decomposition temperature to a lower value and decreased the energy required for biomass decomposition.
