1. Sodium Acid Pyrophosphate is an anhydrous, white powdered solid. it can use as leavening agent and Sequestrant, which complies wtih the speicifiation of FCC as food additives.
2. 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°C, it will be decomposed into sodium meta phosphate.
