Diethylene Triamine Penta (Methylene Phosphonic Acid) Heptasodium Salt, known as DTPMP·Na7, is a sophisticated organophosphorus compound with a vital role in various industrial processes. Understanding its chemical structure, properties, and application spectrum is key to leveraging its full potential. NINGBO INNO PHARMCHEM CO.,LTD. provides this advanced chemical, backed by a deep understanding of its scientific underpinnings.

The chemical structure of DTPMP·Na7 is derived from Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA), where five methylene phosphonic acid groups are attached to the amine backbone of diethylene triamine. The heptasodium salt form (DTPMP·Na7) indicates that seven acidic protons on the phosphonic acid groups have been neutralized by sodium ions, resulting in a highly water-soluble compound. The formula C9H21O15N3P5Na7 and a molecular weight of approximately 727 reflect this complex structure, which is responsible for its exceptional performance characteristics.

The key properties of DTPMP·Na7 include its appearance as a brown transparent liquid, its high solubility in water, and a pH range typically between 7.0-9.0 for a 1% aqueous solution. Crucially, its standout properties are its exceptional scale inhibition capabilities, particularly for barium sulfate, and its strength as a chelating agent. It also exhibits good thermal stability and resistance to hydrolysis, making it suitable for a wide range of operating conditions. These properties make DTPMP·Na7 a versatile compound, far exceeding the performance of simpler phosphonates in many applications.

The applications of DTPMP·Na7 are extensive, spanning several critical industrial sectors. It is widely employed in industrial water treatment as a scale and corrosion inhibitor for cooling water systems and boilers. Its efficacy as a stabilizer for peroxide bleaching in the textile and paper industries is well-documented. Furthermore, it serves as a valuable detergent auxiliary, enhancing cleaning performance. In the oilfield sector, it is used to treat produced water and injection water to prevent scale formation and maintain flow. For those considering to purchase DTPMP·Na7, understanding its technical specifications and performance metrics is important. The price of DTPMP·Na7 reflects its advanced formulation and superior capabilities.
