MAGNESIUM PYROPHOSPHATE Chemical Properties,Uses,Production
Uses
Magnesium pyrophosphate is a colorless monoclinic crystal and can be used as a stabilizer in toothpaste and tooth powder.
Description
Magnesium pyrophosphate has the molecular formula of Mg2P2O7 and the molecular weight of grams per mole. It may be prepared by the solid-state reaction of the dibasic orthophosphate, or alternately by the precipitation of a soluble Mg salt with aqueous pyrophosphoric acid: 2MgHPO4 (or MgNH4PO4) + heat0Mg2P2O7 +H2O (+NH3) MgCl2 (aq)+H4P2O7 (aq)0Mg2P2O7 (solid)+2HCl (aq) In the solution method, the result is the hexahydrate, Mg2P2O7·6H2O. This is a white powder with a CAS number of 13478-16-5 and a molecular weight of 245.4073 g/mol. Its density is 1.71 g/cm3 and it is relatively insoluble in water or ethanol but soluble in acids.
