  Chemical Name: Sodium Acid Pyrophosphate;Disodium Dihydrogen Pyrophosphate
  Molecular formula: Na2H2P2O7
  CAS NO.: 7758-16-9
  Ref. Standard: HG2928-1999
  production capacity:3000 t/a
  Properties: White powder or granular; Bulk density 1.86g/cm3; Soluble in water and insoluble in ethanol; If its aqueous solution is heated together with diluted inorganic acid, it will be hydrolyzed into phosphoric acid; It is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates; If it is heated at a temperature above 220℃, it will be decomposed into sodium metaphosphate.
