Shmp Sodium Hexametaphosphate 68 As Softener Water Treatment
SHMP is prepared by heating monosodium orthophosphate to generate sodium acid pyrophosphate:
2 NaH2PO4 → Na2H2P2O7 + H2O
Subsequently, the pyrophosphate is heated to give the corresponding sodium hexametaphosphate:
3 Na2H2P2O7 → (NaPO3)6 + 3 H2O
followed by rapid cooling.
Product: Sodium Hexametaphosphate 68%
Molecular formula: (NaPO3)6
Molecular weight: 611.17
CAS NO.: 10124-56-8
Properties: White powder, density is 2.484 (20℃), easily soluble in water, but not in organic solution, absorbent to dampness, and turn sticky when absorbed dampness in air. It is possible to form solvent compound with metallic ions such as Ca, Ba, Mg, Cu and Fe; it is a fine agent for water treatment.
