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
