SAPP Sodium Acid Pyrophosphate
Type: ROR15,ROR28,ROR40
ASSAY:95.0%min
Packing:25 kg/bag inner plastic and outer plait
Appearance:white powder
SAPP Sodium Acid Pyrophosphate :White powder or granular;Relative density 1.86g/cm3;Soluble in water and insoluble in ethanol; If its aqueous solution is heated together with diluted inorganic acid, it will be hydrolyzed into Phosphoric Acid; It is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates; If it is heated at a temperature above 220ºC, it will be decomposed into sodium meta phosphate.
