- Key Properties
- Sodium Trimetaphosphate (STMP) has no buffering or sequestering power and, hence, no inherent detergent building properties. However, when reacted with caustic soda, STMP converts rapidly and completely to sodium tripolyphosphate (STPP), which is probably the most efficient builder known on a cost/performance basis. When caustic potash is used in place of caustic soda a mixed sodium/potassium salt of tripolyphosphate with enhanced solubility characteristics is formed.
- By controlling the conversion conditions, STMP can be used as the source of phosphate in a conventional spray-drying detergent process. If no spray tower is available, the ICL Specialty Products Inc., “Batch Fluff Process” can be used for producing a porous, granular product directly from a detergent slurry based on STMP, thus eliminating the spray tower operations completely.
- Low density, high quality granular detergents can be produced without spray drying.
- Both anionic and mixed active detergents with a range of 30 – 60% STPP are possible.
- Product density can be controlled over a range by control of process variables.
- Granulated intermediates can be blended with chlorinated isocyanurates chlorinating compositions to produce dry bleaches or automatic dishwashing compounds.
- A mixed sodium/potassium tripolyphosphate (SKTP) salt can be prepared that possesses enhanced solubility over regular sodium tripolyphosphate.
