one.Item description:
Identify: EPT Tripolyphosphate (ceramic grade 94% sodium tripolyphosphate/STPP Chemical)
Molecular Formular: Na5P3O10
Molecular Weight : 368
Shelf Existence: two years
CAS No.: 13573-18-seven
Physical appearance: White powEPTor granular Simply soluble in water
EPT tripolyphosphate is developed by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate,
NaH2PO4, beneath very carefully managed situations.
two Na2HPO4 + NaH2PO4 #8594 Na5P3O10 + two H2O
In this way, approXiHu (West Lake) Dis.mately two million tons are produced each year.ceramic grade ninety four% sodium tripolyphosphate/STPP Chemical is a colourless salt, which eXiHu (West Lake) Dis.sts both in anhydrous type and as the
hexahydrate. The anion can be explained as the pentanionic chain [O3POP(O)2OPO3]five-.Numerous connected di-, tri-, and polyphosphates are identified incXiHu (West Lake) Dis.Hu (West Lake) Dis. the cyclic triphosphate P3O93-. It binds strongly to steel cations as both a bidentate and tridentate chelating agent.

4.Item employs:
In detergents
The bulk of ceramic grade ninety four% sodium tripolyphosphate/STPP Chemical is eaten as a element of industrial detergents.It serves as a quotbuilder, quot EPT jargon for a water softener. In tough h2o (h2o that is made up of higher concentrations of Mg2+ and Ca2+), detergents are deactivated. Becoming a extremely chargedchelating agent, TPP5- binds to dications tightly and helps prevent them from interfering with the sulfonate detergent.
Food programs
ceramic grade ninety four% sodium tripolyphosphate/STPP Chemical is a preservative for seafood, meats, poultry, and animal feeds.It is common in foodstuff production as E number E451. In foods, ceramic grade 94% sodium tripolyphosphate/STPP Chemical is employed as an emulsifier and to keep dampness. Several governments control the portions authorized in foodstuff, as it can considerably improve the sale excess weight of seafood in particular. The EPT States Food and Drug Administration lists ceramic grade 94% sodium tripolyphosphate/STPP Chemical as quotEPTly recognized as risk-free. quot.
Other makes use of
Other employs (hundreds of hundreds of tons/year) incEPT quotceramics, leather tHangZhou(as masking agent and synthetic tHangZhou agent – SYNTAN), anticaking, environment retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze.
