How is polyphosphoric acid made
Polyphosphates arise by polymerization of phosphoric acid derivatives. The process begins with two phosphate units coming together in a condensation reaction. 2 H(PO4) ⇌ (P2O7) + H2O The condensation is shown as an equilibrium because the reverse reaction, hydrolysis, is also possible. The process may continue in steps; at each step another (PO3) unit is added to the ch… WebPolyphosphoric acid, ca 84% (as phosphorus pentoxide), Thermo Scientific Chemicals £44.30 / 500mL Product Code. 10481431 Polyphosphoric acid, pure, >84% phosphate (as P 2 O 5 ), Thermo Scientific Chemicals £119.00 / 2.50kg Customers who viewed this item also viewed Viewing 1 - 3 of 5 Merck Amicon ™ Ultra-4 Centrifugal Filter Unit
