1. Basic Information
Alias: TSPP
Molecular formula: Na4P2O7
Molecular weight: 265.90
CAS no. : 7722-88-5
EINECS : 231-767-1
Customs Code: 28353990
2. Physicochemical Properties
Appearance : white powder or crystal
Relative density : 2.534g/cm
Melting point : 880 ºC
Boiling point : 938 ºC
Solubility : soluble in water.
Specialty : The solubility of 100g water at 20ºC is 6.23, and its aqueous solution is alkaline.,insoluble in alcohol. Water solution is stable below 70ºC, and hydrolyzes to disodium hydrogen phosphate after boiling. In the weathering, the crystal loses its drying in air at 100 ºC, and easy to absorb moisture or deliquescence in the air.
