Beryllium Peroxyphosphate

Beryllium Peroxyphosphate Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  The chemistry of beryllium phosphates is far from complete. Beryllium peroxyphosphate has never been prepared. The chemistry involved and the physical properties of these compounds remain little known. Only a few references in the literature are available and most of these are dated before 1900. The compounds were identified by analysis, i.e. %Be, %P and %O as an oxidant. Parsons wrote a monograph “The Chemistry of Beryllium and Its Compounds” in 1910 but had little to add to what was already known.
  Beryllium peroxyphosphates could be prepared by both solid-state or solution methods. However, it is likely that the two sets of compounds would differ. For the monoperoxyphosphates, one would get Be(HPO5)2 for the former method and (BeOH)(HPO5) for an aqueous solution. The question of hydrates remains unknown.
  In the solution method, one could use 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
