Uses and synthesis of sodium hexametaphosphate powder

sodium hexametaphosphate powder is a kind of sodium metaphosphate polymer, also known as "sodium polymetaphosphate", "sodium polymetaphosphate", "sodium metaphosphate glass", "Graham's salt", the appearance is colorless transparent glassy solid or white powder, sodium hexametaphosphate is a kind of sodium metaphosphate polymer. 

It is also called "sodium polyphosphate", "sodium polyphosphate", "sodium metaphosphate vitreous", "Graham's salt", with the appearance of colorless transparent glassy solid or white powder, sodium hexametaphosphate CAS 10124-56-8 has a large solubility in water, but the speed of dissolution is slow, and the aqueous solution is acidic reaction.

The complex of divalent metal ion is more stable than that of monovalent metal ion. sodium hexametaphosphate Raw Materials is easily hydrolyzed into orthophosphate in warm water, acid or alkali solution.

Applications / Functions of sodium hexametaphosphate powder

1. sodium hexametaphosphate CAS 10124-56-8 Used as food quality improver, pH adjuster, metal ion chelating agent, dispersant, swelling agent, etc. in food industry.
2. sodium hexametaphosphate powder Used as general analytical reagent, water softener, also used for photographic washing and printing and dyeing
3. sodium hexametaphosphate Raw Materials Used as water softener, detergent, antiseptic, cement hardening agent, fiber and bleaching and dyeing cleaning agent, also used in medicine, food and petroleum, printing and dyeing, tanning, paper and so on.

Tissue improver; emulsifier; stabilizer; chelating agent. Used alone less often, usually mixed with pyrophosphate and metaphosphate. Mixing agent is mainly used in ham, sausage, minced fish and so on as water retention, tenderization and softening of old residual animal meat, such as tissue improvement agent. It is also used to prevent crystallization of canned crab and as a pectin solubilizer.

Physicochemical Property of sodium hexametaphosphate powder

sodium hexametaphosphate powder is white crystalline powder, specific gravity is 2.484 (20℃), easily soluble in water but insoluble in organic solvents with strong moisture absorption. It has significant chelating ability for metal ions Ca and Mg.

Colorless transparent glassy flakes or white granular crystals. sodium hexametaphosphate CAS 10124-56-8 Soluble in water, insoluble in organic solvents.

Production methodprocess of sodium hexametaphosphate powder

Food grade products are usually produced by the sodium dihydrogen phosphate method. Use soda ash to neutralize phosphoric acid, control Ph value between 4.0 and 4.4, that is, sodium dihydrogen phosphate solution; this solution is sent to the polymerization furnace, heated at 700 ℃ and dehydrated for 15-30min, that is, molten sodium hexametaphosphate; and then add water to sharply cooled tablets, crushed that is, sodium hexametaphosphate Raw Materials.

Phosphorus pentoxide method will be oxidized by burning yellow phosphorus in dry air flow, cooling and phosphorus pentoxide and soda ash according to a certain proportion (Na2O: P2O5 = 1 ~ 1.1) mixed. The mixed powder is indirectly heated in a graphite crucible to make it dehydrated and melted, and the generated sodium hexametaphosphate melt is quenched and pulverized to produce industrial sodium hexametaphosphate powder.
