food additive
Disodium pytophosphate(SAPP)
Alias: Diphosphoric acid disodium salt
Molecular formula: H2Na2O7P2
MW: 221.94
CAS No. : 13472-36-1
Character: White powder or crystal. Relative density is 2.534, melting point 880 °C, boiling point 93.8 °C.when the water solubility of 100g for 6.23, its aqueous solution is alkaline; not soluble in alcohol. Aqueous solution at 70 °C, the following is still stable. It is boiling and will become disodium hydrogen phosphate. In dry air, it lose crystal water at 100 °C.and it is easy to absorb moisture in the air and deliquescence. alkaline earth metal ions can generate complex with it
Uses: electroplating industry;The formation of complexes with iron. Wool and wool textile industry as a degreasing agent and hair bleaching agent. Paper industry for bleaching paper and plant fibers. Printing and dyeing industry as dyeing, bleaching fine when the additive.Chemical industry as a toothpaste additive ,it is used with DCP to play a stabilizing effect on the formation of colloid, And can be used for production of synthetic detergent and shampoo ointment products.
