Barium Peroxyphosphate

Barium Peroxyphosphate Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Barium peroxyphosphate has remained unknown and little to no publications concerning this salt are available on the scientific literature. Like the other alkaline earths, Barium peroxyphosphates could be prepared by both solid-state or solution methods. The two sets of compounds would likely differ. For the monoperoxyphosphates, one would get BaHPO5 for the former method and perhaps a hydrate for an aqueous solution. The question of degree of hydration remains unknown.
  In the solution method, one could use either the acid, H3PO5 or the potassium salt K2HPO5. Whether the solution should be acidic or basic is not known. Like the other alkaline earths, it is probably best to prepare the acid in a nonaqueous solution like carbon tetrachloride and then add the potassium compound for the basic solution:
  P2O5 + 2H2O2 +H2O ? 2H3PO5
  2H3PO5 + KOH ? K2HPO5
  To either of these is added a barium compound to form the monoperoxyphosphate:
  Ba(OH)2 + K2PO5 ? BaHPO5 +H2O
  For the diperoxy compounds, the potassium monoperoxyphosphate compound is transformed to the diperoxyphosphate compound, in a nonaqueous solution at low temperature:
  K2HPO5 + P2O5 ? K2P2O8
  For barium, the probable compounds that will be formed are:
  BaHPO5
  Ba2P2O8
  Other possible compounds are:
  Ba(H2PO5)2
  Ba(H2P2O8)2
