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 .
ASTM C1293: "Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction". It is a long-term confirmation test (1 or 2 years) at 38 °C in a water-saturated moist atmosphere (inside a thermostated oven) with concrete prisms containing the aggregates to be characterised mixed with a high-alkali ...
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]
disodium phosphate dodecahydrate: Na 2 HPO 4 ·12H 2 O: 10039–32–4 trisodium phosphate (anhydrous, hexagonal) Na 3 PO 4: trisodium phosphate (anhydrous, cubic) Na 3 PO 4: 7601–54–9 trisodium phosphate hemihydrate: Na 3 PO 4 ·0.5H 2 O: trisodium phosphate hexahydrate: Na 3 PO 4 ·6H 2 O: trisodium phosphate octahydrate: Na 3 PO 4 ·8H 2 ...
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 hexametaphosphate is the alkali salt of one of the series of polymetaphosphoric acids (acids formed by the polymerization of phosphate groups). [14] Hexametaphosphoric acid was first made in 1825 by the German chemist Johann Frederich Philipp Engelhart (1797-1853). [15]
The separation buildings were massive windowless concrete structures, 800 feet (240 m) long, 80 feet (24 m) high and 65 feet (20 m) wide, with concrete walls 3 to 5 feet (0.91 to 1.52 m) thick. Inside the buildings were canyons and galleries where a series of chemical processing steps separated the small amount of plutonium from the remaining ...
Trisodium citrate is a chemical compound with the molecular formula Na 3 C 6 H 5 O 7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart taste, and is a mild alkali.
