Physical and chemical properties of Sodium Tripolyphosphate

What is Sodium Tripolyphosphate

Sodium Tripolyphosphate (STPP), whose chemical formula is Na₅P₃O₁₀,

is an important inorganic compound belonging to the polyphosphate family.

It is a white crystalline powder or particle made from phosphate polymerization at high temperature,

easily soluble in water, and has excellent chelating, dispersing and softening properties.

Main characteristics of sodium tripolyphosphate
Chemical properties:

It has strong chelating ability and can be combined with calcium,

magnesium and other metal ions in water to prevent the formation of scale.

It has good dispersion and can prevent dirt particles from regathering.

Stable in alkaline environment, suitable for alkaline products such as detergents.

Physical properties:

The appearance is white powder or particle.

Soluble in water, aqueous solution is alkaline.

Strong hygroscopicity, need to be stored in a dry environment.

Preparation of sodium tripolyphosphate
Sodium tripolyphosphate is usually prepared by the following steps:

The phosphoric acid (H₃PO₄) reacted with sodium hydroxide (NaOH) to form sodium phosphate (Na₃PO₄).

Sodium phosphate is dehydrated and polymerized at high temperature to produce sodium tripolyphosphate.

Main uses of sodium tripolyphosphate
Detergent industry:

As a washing aid, soften water quality and enhance decontamination ability.

Prevent dirt redeposition, maintain detergent alkaline environment.

Food Industry:

As a food additive (E451), it is used for water retention, texture improvement and corrosion protection.

Industrial Water treatment:

Used for boiler water and cooling water treatment to prevent scaling and corrosion.

Ceramics and Building Materials:

As a dispersant, improve the fluidity of ceramic slurry.

Textile industry:

As a printing and dyeing aid, improve dyeing uniformity and color fastness.

Other areas:

Petroleum industry, metal processing, paper industry, coating industry, etc.

Environmental problems of sodium tripolyphosphate
Environmental impact: The decomposition of sodium tripolyphosphate in the water body may lead

to eutrophication of the water body, causing excessive algal reproduction and destroying the ecological balance.

Substitution trend: With the strengthening of environmental regulations,

the application of sodium tripolyphosphate in detergent

and other fields is gradually replaced by non-phosphorus or low-phosphorus alternatives (such as zeolite, polycarboxylate).
