Phosphorus pentoxide hydrolysis
WebChemical properties: Phosphorus pentoxide is a dryer and dehydrating agent due to exothermic hydrolysis that suffers in water, where energy of -177 kJ is released. P 4 O 10 + 6 H 2 O → 4 H 3 PO 4 This reaction is also observed in the presence of amides, where the pentoxide can form a hydroxide and the amide is converted to nitrile.
