Stability and Reactivity of Sodium Metaphosphate NaPO3
Sodium Metaphosphate NaPO3 is an inorganic compound, a high-molecular-weight sodium polyphosphate composed of two long-chain metaphosphates with opposite helical directions and a common axis. The Na2O/P2O5 ratio is about 1.0. It is colorless transparent crystal or white powder. It is easy to absorb moisture in the air. Soluble in water and inorganic acids, the aqueous solution is alkaline, insoluble in ethanol and organic solvents. It can be obtained by high-temperature melt polymerization of sodium dihydrogen phosphate. It is used for the softening of boiler water and the separation and purification of certain heavy metal ions. Food grade Sodium Metaphosphate NaPO3 can be used as food emulsifier, chelating agent and tissue modifier.
