Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent , builder , lubricant , food additive , stain remover , and degreaser .
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), [1]) is an inorganic compound with formula Na 5 P 3 O 10.It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.
Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4).Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates.
Oxygen cleaning may be required for concentrations as low as 23% [3] Other common specifications for oxygen cleaning include ASTM G93 and CGA G-4.1. [4] Cleaning agents used range from heavy-duty industrial solvents and detergents such as liquid freon, trichlorethylene and anhydrous trisodium phosphate, followed by rinsing in deionised water ...
The comparable cleaning product in Canada and the US is trisodium phosphate, also known as "TSP". However, due to environmental concerns about the impact of phosphorus on lakes and streams, products labeled TSP may not actually contain any trisodium phosphate. "Sugar Soap" in the US is generally a cosmetic product. If sugar is actually used in ...
Chemicals added to the solution range from dish soap and glass cleaner to trisodium phosphate and etching salt. In sub-freezing temperatures, anti-freezing chemicals are added to the solution to prevent it from crystallizing on the pane before it is sluiced off.
Phosphate-free detergents are sold as eco-friendly detergents. In the 21st century phosphates began to be reduced in percentage terms as an ingredient, leading to a New York Times report that said "low- or phosphate-free dishwasher detergents it tested, including those from environmentally friendly product lines that have been on the market for ...
Trisodium trimetaphosphate is produced industrially by heating sodium dihydrogen phosphate to 550 °C, a method first developed in 1955: [5] 3 NaH 2 PO 4 → Na 3 P 3 O 9 + 3 H 2 O. The trimetaphosphate dissolves in water and is precipitated by the addition of sodium chloride (common ion effect), affording the hexahydrate. [6]
