Disodium Phosphate

Appearance: White Powder

Other Name: Metaphosphoric Acid;Sodium Hydrogen Phosphate

Executive Standard: GB 25568-2010(Food Grade) HG/T2965-2009(Technical Grade )

Advantages

The dodecahydrate is white crystal with relative density 1.52, weathered in the air easily, losing quinque-molecular crystallization water easily, forming anhydride after losing crystallization water at 100°C, decomposing to sodium pyrophosphate at 50°C; anhydride is white powder with hygroscopy. Both are easily soluble in water, aqueous solution is slightly alkaline, alcohols insoluble.
