DiSodium hydrogen Phosphate (DSP)
Molecular formula: Na2HPO4.nH2O (n=0,12)
Molecular weight: 358.0
Standard executed: HG/T2965-2009(Technical Grade)
CAS Number: 7558-79-4(Anhydrous),10039-32-4(12H2O)
Properties:
White or colorless crystalline free flowing solid, efflorescent in air, easily soluble in water, but insoluble in alcohol, its water solution is slightly alkaline, relative density at 1.52 g/cm3, melting point at 35℃
Application:
It is used in conjunction with trisodium phosphate in foods and water softening treatment. In foods, it is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, it is used as an anti-caking additive in powdered products.It is used in desserts and puddings, e.g. Cream of Wheat to quicken cook time, and Jell-O Instant Pudding for thickening. In water treatment, it retards calcium scale formation.It is also found in some detergents and cleaning agents.
Heating solid disodium phosphate gives the useful compound tetrasodium pyrophosphate
