disodium hydrogen phosphate

CAS NO:7558-79-4

Alias: Dibasic Sodium Phosphate

Molecular formula: Na2HPO4·12H2O

Molecular weight: 358.14


Use:

Boiler softener, used for tanning leather, fabric weight additive wood and paper flame retardant, glaze and flux.The dyeing agent is used as a stabilizer for bleaching of hydrogen peroxide in the printing and dyeing industry.It's the stuff that makes sodium phosphate and other phosphate。

Specialty:

In the air, it is easy to be weathered, easily losing five molecules of crystal water to form seven water(Na2HPO4.7H2O).Soluble in water, insoluble in alcohol.The aqueous solution has a slightly alkaline reaction (the PH of 0.1-1n solution is about 9.0).In 100 ℃ water of crystallization anhydride, lost 250 ℃ is decomposed into sodium pyrophosphate


Specification:HG/T 2965-2009
