DTPMP (Diethylenetriamine pentamethylene phosphonic acid)

Diethylenetriamine pentamethylene phosphonic acid is a multi-toothed chelating agent and one of the phosphonates that act as an inhibitor of crystal formation. This phosphonate is also known as methylene phosphonic acid. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Physical and Chemical properties of DTPMP:

Methylene phosphonic acid is generally in the form of salt; Because its acidic state has little solubility in water. In high-temperature environments (above 210) DTPMP has better anti-corrosion and anti-fouling properties than other phosphates (ATMP, HEDP). Also, the seven sodium salt of this substance, DTPMP.NA7, has anti-fouling properties, especially in barium sulfate environment, and can be used as a stabilizer of peroxides, bleaches, detergents, water used in industry and municipality.

Chemical Structure Depiction

The structure of DTPMP:

These phosphonates are structurally similar to amino polycarboxylates such as EDTA. The stability of metal complexes increases with the increasing number of phosphonic acid groups. This compound contains nitrogen and phosphorus atoms in the molecule, which can form a stable complex with alkali and intermediate metals.

DTPMP Uses:

• Detergents and Cleaners
• water treatment
• Anti-fouling
• Anti-corrosion
• Chelating agent
• Flocculation
• Sediment inhibitor
• Scaling inhibitor
• Agriculture industry
• DTPMP is used in chemical, leather processing, paper pulpboard, paints lacquers varnishes, and textile processing.

Application of DTPMP in Water Treatment:

Phosphonates are frequently used in the production of drinking water as an anti-fouling agent to prevent the deposition of salts in reverse osmosis (RO membrane) filters. Among phosphonates, DTPMP has been noted for its technical properties.

DTPMP is an Effective Agent in Detergents and Cleaners:

Phosphonates are essential compounds used in detergent formulations. They have a wide range of functional groups required for household and industrial detergents. Among other raw materials, phosphonates are used to stabilize water hardness, remove stains, stabilize disinfectants or bleach compounds.
