Product Detail
99% High Quality Original Powder Disodium Hydrogen Phosphate CAS 7758-79-4 with Safe Delivery
Description
Disodium phosphate (DSP), or sodium hydrogen phosphate, or sodium phosphate dibasic, is the inorganic compound with the formula Na2HPO4. It is one of several sodium phosphates. The salt is known in anhydrous form as well as forms with 2, 7, 8, and 12 hydrates. All are water-soluble white powders; the anhydrous salt being hygroscopic.
The pH of disodium hydrogen phosphate water solution is between 8.0 and 11.0, meaning it is moderately basic:
HPO42− + H2O ⇌ H2PO4− + OH−
Application of Sodium Tripolyphosphate (STPP)94%
1)In Detergents
The majority of STPP is consumed as a component of commercial detergents.
It serves as a "builder," industrial jargon for a water softener. In hard water
(water that contains high concentrations of Mg2+ and Ca2+), detergents are
deactivated. Being a highly chargedchelating agent, TPP5- binds to dications
tightly and prevents them from interfering with the sulfonate detergent.
2)Food Applications
STPP is a preservative for seafood, meats, poultry, and animal feeds.It is common
in food production as E number E451. In foods, STPP is used as an emulsifier and
to retain moisture. Many governments regulate the quantities allowed in foods,
as it can substantially increase the sale weight of seafood in particular. The UnitedStates Food and Drug Administration lists STPP as "generally recognized as safe.".
3)Other Uses
Other uses (hundreds of thousands of tons/year) include "ceramics, leather
tanning(as masking agent and synthetic tanning agent - SYNTAN), anticaking,
setting retarders, flame retardants, paper, anticorrosion pigments, textiles,
rubber manufacture, fermentation, antifreeze.
