Sodium tripolyphosphate/ STPP
Industrial grade 96% CAS 7758-29-4
Food grade 85% CAS 7758-29-4
Molecular formula Na5P3O10
Molecular weight 367.86
【 Performance Characteristics 】
White granular or powder, showing a density of 0.35-0.90G/CM3,
melting point 622 degrees Celsius.
It is easily soluble in water, the aqueous solution is alkaline,
and the PH of 1% aqueous solution is 9.7.
It is gradually hydrolyzed into phosphite in water, and has good
ionic ability of metal complexation.
It can be complexed with calcium/magnesium/iron and
other metal ions to produce soluble complexes. It softens hard
water. As a kind of inorganic surfactant,
it has some properties of organic surfactant.
【 Purpose 】
Mainly used for synthetic detergent as an additive/soap agent and
to prevent bar soap grease precipitation and
frosting. It has a strong emulsifying effect on lubricating oil and
fat, and can be used to
adjust the PH value of buffer soap liquid, industrial water
softener/tanning and
pre-tanning agent/dyeing agent/paint/kaolin/magnesium oxide/calcium
carbonate and
other industries to prepare suspension as a dispersant, drilling
mud dispersant,
and paper industry as an anti-oil agent.
What are chemical raw materials
The definition of Chemical Raw Materials
Chemical raw materials refer to natural or synthetic basic
substances used in the production of chemicals, materials or
finished products, and they are the cornerstone of the chemical
industry. They are transformed into industrial products of higher
value through physical, chemical or biological processing and are
widely used in fields such as energy, medicine, agriculture,
construction and electronics.
Classification of chemical raw materials
According to their sources, uses and chemical properties, chemical
raw materials can be classified into the following major
categories:
Classify by source
Inorganic chemical raw materials
Derived from minerals or inorganic reactions, such as sulfur (S),
hydrochloric acid (HCl), sulfuric acid (H₂SO₄), caustic soda
(NaOH), sodium carbonate (Na₂CO₃), etc.
Typical uses: fertilizer, glass, ceramics, water treatment.
Organic chemical raw materials
Carbon-containing compounds, mainly derived from petroleum
(petrochemical products), natural gas, coal or biomass such as
ethylene (C₂H₄), benzene (C₆H₆), methanol (CH₃OH).
Typical uses: plastics, synthetic fibers, pharmaceuticals, dyes.
2. Classify by use
Basic raw materials:
It is used for the production of other chemicals, such as ethylene
and propylene (plastic raw materials) produced from petroleum
cracking, or ammonia (NH₃, used in fertilizers).
Intermediate
Transition products in the production process, such as ethylene
oxide (used to manufacture ethylene glycol, that is, antifreeze).
Terminal chemicals
It is directly used in industry or consumption, such as
polyethylene (PE) plastic pellets, coatings, and active ingredients
in pharmaceuticals.
3. Classification by form
Gases: such as oxygen (O₂), nitrogen (N₂), chlorine (Cl₂).
Liquids: such as sulfuric acid, benzene, ethanol.
Solids: such as sulfur, soda ash (Na₂CO₃), polymer particles.
