Sodium trimetaphosphate (also STMP), with formula Na3P3O9, is a metaphosphate of sodium. It has the empirical formula NaPO3. It is the sodium salt of trimetaphosphoric acid. It is a colourless solid that finds specialised applications in food and construction industries. STMP is prepared by heating samples sodium polyphosphate. Although drawn with a particular resonance structure, the trianion has D3d symmetry. Hydrolysis of the ring leads to the acyclic sodium triphosphate: Na3P3O9 + H2O → H2Na3P3O10 The main reactions of the triphosphate anion is by nucleophiles, including amines.
