1.BASSIC INFORMATION
A lias: DSP
Formula : Na2HPO4�·12H20
Molecular weight: 358.14
CAS NO. : 10039-32-4
HS Code: 28352200
EINECS: 231-448-7
2.PROPERTIES
Appearance: White powder, flake or granular crystal
Type: Industrial Grade
Density: 1.52 g/cm3
Melting point: 34.6C
Solubility: Soluble in water, its aqueous solution is alkaline. >=10 g/100 mL (20C).
Characteristics: It is easy to weather in the air and then lose five molecules of crystal water to form Na2HPO4�·7H20. At 100 �°C, the crystal water is lost to form anhydrous substance and it breaks down into TSPP at 250 �°C.
3.APPLICATIONS
It is used as a fire retardant for fabric, wood and paper, boiler water softener, food additive, buffer, solder, tanning agent, etc.
