- Key Properties
- The ring structure of STMP makes it a particularly reactive polyphosphate molecule. The "stored energy" of the STMP ring is the driving force for nucleophilic addition reactions involving this special phosphate.
- Sodium trimetaphosphate (STMP) is a salt of a strong base and a strong acid. STMP undergoes alkaline hydrolysis when reacted with caustic soda to yield sodium tripolyphosphate. When caustic potash is used in place of caustic soda, a mixed sodium/potassium salt of tripolyphosphate with enhanced solubility characteristics is formed.
- STMP also reacts with the fluoride anion, ammonia, amines and alkoxy groups to form the linear polyphosphate derivatives.

- Main Applications
- Low density, high quality granular detergents can be produced without spray drying.
- Both anionic and mixed active detergents with a range of 30-60% STP are possible.
- Granulated intermediates can be blended with chlorinated isocyanurates chlorinating compositions to produce dry bleaches or automatic dishwashing compounds.
- Mixed sodium/potassium tripolyphosphates can be prepared that possess enhanced solubility.
- Consumer and industrial detergents and cleaning products, particularly liquid products that exhibit enhanced tripolyphosphate solubility.
