TETRAKIS(HYDROXYMETHYL)PHOSPHONIUM SULFATE(55566-30-8) is incompatible with oxidizing materials and alkalis. | [Air & Water Reactions]
Water soluble. | [Fire Hazard]
This chemical is probably combustible. | [Description]
Tetrakis(hydroxymethyl)phosphonium sulfate (THPS) is an organophosphorus compound. It is used as a precursor in the flame retardant manufacturing process, a biocide in water systems, and a tanning agent in the leather industry. THPS is a safe aqueous solution with antimicrobial properties that is significantly less toxic, effective at lower concentrations, and more biodegradable than other traditional biocides.
| [Uses]
Tetrakis(hydroxymethyl)phosphonium sulfate is a green and environmentally friendly quaternary phosphonium salt bactericide, mainly used as a biocidal agent. It is widely used in water treatment, oil fields, papermaking and other industries. Its outstanding advantage is that it can be rapidly degraded into completely harmless substances after use, greatly reducing the environmental impact of these industries. It is also an internationally recognized permanent flame retardant for pure cotton and polyester-cotton fabrics. | [Flammability and Explosibility]
Nonflammable | [Synthesis]
Add sulfuric acid and formaldehyde into the reaction kettle, open the gas-liquid circulation mixing reaction pump, add phosphine into the gas-liquid circulation mixing reaction pump, at 50-60 ℃ through the gas-liquid circulation mixing reaction device to | [Advantages]
Advantage of the wet white tanned leathers, using THPS offers:
a light color and pastel shades
They can reach shrink temperatures of at least 70 grad C
High softness
Good lightness
Feeling of naturalness
Pleasant to the touch
Beauty that lasts for a long time
Can be burned without the risk of hexavalent chromium formation
