Product Description

DISODIUM HYDROGEN PHOSPHATE 

1.BASSIC INFORMATION
Alias:                                  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: 34.6°C
Solubility:      Soluble in water, its aqueous solution is alkaline. >=10 g/100 mL (20ºC).
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.
