- PPZ Purify it by zone melting, by crystallisation from pet.ether, n-hexane or *benzene, and by sublimation. [van der Huizen et al. J Chem Soc, Dalton Trans 1311 1986, Meirovitch et al. J Phys Chem 88 1522 1984, Alcock et al. J Am Chem Soc 106 5561 1984; Winter & van de Grampel J Chem Soc, Dalton Trans 1269 1986.
- Pyrophosphate can be removed from phosphoric acid by diluting with distilled H2O and refluxing overnight. By cooling to 11o and seeding with crystals obtained by cooling a few millilitres in a Dry-ice/acetone bath, 85% orthophosphoric acid crystallises as H3PO4.H2O.
