Tetrasodium pyrophosphate Chemical Properties,Uses,Production

Description

Sodium pyrophosphate, also called Tetrasodium pyrophosphate or TSPP is used in the laboratory as a buffering agent. The compound has been shown to be useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples. Tetrasodium pyrophosphate is an odorless, white powder or granules. It is used in water softener, buffering agent, thickening agent, dispersing agent, wool de-fatting agent, metal cleaner, soap and synthetic detergent builder, general sequestering agent, in electrodeposition of metals. It also acts as a tartar control agent in toothpaste and dental floss. In addition, it is used as a chelating agent in antimicrobial studies. It is also used as a food additive in common foods such as chicken nuggets, crab meat and canned tuna.

Chemical Properties

white crystalline powder or colourless crystals

Uses

Tetrasodium Pyrophosphate is a coagulant, emulsifier, and sequestrant that is mildly alkaline, with a ph of 10. it is moderately soluble in water, with a solubility of 0.8 g/100 ml at 25°c. it is used as a coagulant in noncooked instant puddings to provide thicken- ing. it functions in cheese to reduce the meltability and fat separa- tion. it is used as a dispersant in malted milk and chocolate drink powders. it prevents crystal formation in tuna. it is also termed sodium pyrophosphate, tetrasodium diphosphate, and tspp.

Uses

Pharmaceutic aid.

General Description

Odorless, white powder or granules. Mp: 995°C. Density: 2.53 g cm-3. Solubility in water: 3.16 g / 100 mL (cold water); 40.26 g / 100 mL boiling water. Used as a wool de-fatting agent, in bleaching operations, as a food additive. The related substance Tetrasodium pyrophosphate decahydrate (Na4P2O7 0H2O) occurs as colorless transparent crystals. Loses its water when heated to 93.8°C.

Reactivity Profile

Tetrasodium pyrophosphate is basic. Reacts exothermically with acids. Incompatible with strong oxidizing agents. Decomposes in ethyl alcohol.

Hazard

Toxic by inhalation.

Safety Profile

Poison by ingestion, intraperitoneal, intravenous, and subcutaneous routes. It is not a cholinesterase inhibitor. When heated to decomposition it emits toxic fumes of POx and Na2O.
