SAPP (Sodium acid pyrophosphate)
Properties:
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 220 , it will be decomposed into sodium meta phosphate.
Packing and storage:
In 25kg, 50kg, 1000kg net bags, store at a cool, dry and well ventilated place.
