WHAT IS A DISPERSING AGENT, OR DEFFLOCULATING AGENT?
Sodium Hexametaphosphate (SHMP) is a dispersing agent prevents flocculation, or the combining of suspended matter into aggregates large enough for gravity to accelerate their settling out.
Divalent and trivalent cations such as Sodium Hexametaphosphate (SHMP) are used in water solutions to facilitate flocculation of insoluble particles in suspension, especially colloidal size particles like clay and organic matter that have negative surface charges.

Addition of divalent or trivalent cations is frequently used in water treatment to remove a combination of inorganic and organic matter as well as living microscopic organisms through flocculation followed by filtration.
Dispersing agents such as Sodium Hexametaphosphate (SHMP) are more commonly used in laboratory procedures to sustain suspensions and estimate particle size distribution.

They are commonly used as a component of detergents, for keeping pigments dispersed in paints and in photography where they find special applications to prevent spotting of films and photographs.
While you can't see it, Sodium Hexametaphosphate (SHMP) is hiding just beyond the shadows of your drinking water and likely in the paint you have used in your house.

PREPARATION of SODIUM HEXAMETAPHOSPHATE (SHMP):
Sodium Hexametaphosphate (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.

REACTIONS of SODIUM HEXAMETAPHOSPHATE (SHMP):
Sodium Hexametaphosphate (SHMP) hydrolyzes in aqueous solution, particularly under acidic conditions and/or heat, to sodium trimetaphosphate and sodium orthophosphate.

HISTORY of SODIUM HEXAMETAPHOSPHATE (SHMP):
Sodium Hexametaphosphate (SHMP) is the alkali salt of one of the series of polymetaphosphoric acids (acids formed by the polymerization of phosphate groups).
Hexametaphosphoric acid was first made in 1825 by the German chemist Johann Frederich Philipp Engelhart (1797-1853).
For his doctoral thesis, Engelhart intended to determine whether iron was responsible for the red color of blood.

In order to purify his blood samples, Engelhart had found that he could coagulate the blood serum's albumin (dissolved proteins) by treating the blood with phosphoric acid.
This contradicted the findings of the famous Swedish chemist Jöns Jacob Berzelius, who had stated that phosphoric acid did not coagulate water-soluble proteins such as egg white.[16]

Berzelius and Engelhart collaborated with the intention of resolving the contradiction; they concluded that Engelhart had produced a new form of phosphoric acid simply by burning phosphorus in air and then dissolving the resulting substance in water.
However they did not determine the new acid's composition.

That analysis was accomplished in 1833 by the Scottish chemist Thomas Graham, who named the sodium salt of the new acid "metaphosphate of soda".
Graham's findings were confirmed by the German chemists Justus von Liebig and Theodor Fleitmann.
In 1849 Fleitmann coined the name "hexametaphosphoric acid".

By 1956, chromatographic analysis of hydrolysates of Graham's salt (sodium polyphosphate) indicated the presence of cyclic anions containing more than four phosphate groups; these findings were confirmed in 1961.
In 1963, the German chemists Erich Thilo and Ulrich Schülke succeeded in preparing Sodium Hexametaphosphate (SHMP) by heating anhydrous sodium trimetaphosphate.

PRODUCTION METHOD of SODIUM HEXAMETAPHOSPHATE (SHMP):
*Sodium dihydrogen phosphate:
The soda solution was first subject to neutralization reaction with phosphate acid at 80~100 ℃ for 2h; the resulting sodium dihydrogen phosphate solution was concentrated by evaporation, cooled and crystallized to obtain sodium dihydrogen phosphate dihydrate and heated to 110~230 ℃ to remove two crystal water; further be subject to heating to remove the structural water; further being heated to 620 ℃ for dehydration to result in the molten sodium metaphosphate and further polymerized into Sodium Hexametaphosphate (SHMP), and discharged; apply chilling shock fro 650 ℃ to 60~80 ℃ for flaking, and crush to obtain the hexametaphosphate products.

Sodium Hexametaphosphate (SHMP)'s reaction formula is as below:
Na2CO3 + 2H3PO4 + H2O → 2NaH2PO4•2H2O + CO2 ↑
NaH2PO4•2H2O [△] → Na2H2PO4 + 2H2O
2NaH2PO4 [△] → Na2H2P2O7 + H2O
Na2H2P2O7 → 2NaPO3 + H2O
6NaPO3 [△] → (NaPO3)6

*Phosphorus pentoxide method:
put the yellow phosphorus into a steam of dry air for combustion and oxidation, the cooling obtained phosphorus pentoxide is mixed together with soda in certain ratio (Na2O: P2O5 = 1~1.1).

Put the mixed powder in a graphite crucible and heated indirectly to have it dehydrated and agglomerated, the resulting Sodium Hexametaphosphate (SHMP) is subject to flaking upon chilling shock and pulverized to obtain industrial hexametaphosphate products.

The reaction formula is as below:
P4 + 5O2 → 2P2O5
P2O5 + Na2CO3 → 2NaPO3 + CO2 ↑
6NaPO3 [△] → (NaPO3)6
