Stabilizers 231-767-1 Tetrasodium Pyrophosphate Food Grade
TSPP 96.5% Food Grade Trisodium Phosphate Na4P2O7 Stabilizers 231-767-1
Properties
Sodium pyrophosphate is white powder or crystal with relative density of 2.534, melting point of 880 ℃ and boiling point of 938 ℃. The solubility of sodium pyrophosphate is 6.23 in 100g water at 20 ℃, and its aqueous solution is alkaline. The aqueous solution is stable below 70 ℃, and hydrolyzes to disodium hydrogen phosphate when boiling. It is weathered in dry air and loses crystal water at 100 ℃. Easy to absorb moisture in the air and deliquescence. It can form complex with alkaline earth metal ions and white silver pyrophosphate when it meets with Ag +. Sodium pyrophosphate can react with metal ions. The pH value of 1% aqueous solution is 10.0-10.2.

Application
Sodium pyrophosphate is used as a chelating agent for metal ions, such as copper in electroplating solution. Used as rust remover in machining. Used as stabilizer of hydrogen peroxide. The bleaching agent and wool degreasing agent were compounded with sodium hydrosulfite. In water treatment, it is used as softener and boiler scale remover. When calcium hydrogen phosphate is used in toothpaste, sodium pyrophosphate is added to form colloid and stabilize it. It is used as dispersant, anticoagulant, emulsifier and quality improver in chemical industry and food industry. It can also be used as raw material for other pyrophosphates.
