dtpmp na7
DTPMP•Na7 is the abbreviation of heptasodium diethylenetriaminepenta(methylene phosphonic acid), which is an important water treatment agent and multifunctional chemical. The following is its relevant introduction:
- Basic Information
- Molecular formula: C9H21O15N3P5Na7
- Molecular weight: 727
- CAS number: 22042 - 96 - 2 (x - Na), 68155 - 78 - 2 (7 - Na)
- Appearance: Reddish-brown liquid
- Performance Characteristics
- Excellent scale inhibition performance: It can form stable complexes with metal ions such as calcium, magnesium, and barium in water. It has a good scale inhibition effect on insoluble salts such as barium sulfate and calcium carbonate. It can effectively prevent the formation of scale on the surface of equipment and in pipelines, improve the heat transfer efficiency of the equipment and the operational stability.
- Strong chelating ability: As an efficient chelating agent, it can undergo chelation reactions with a variety of metal ions, enclosing the metal ions in the chelate and reducing the activity of the metal ions in water. Thus, it can avoid the metal ions participating in some unfavorable chemical reactions, such as corrosion reactions and precipitation reactions.
- Good stability: It has good chemical stability and thermal stability. It can maintain good performance within a wide range of temperatures and pH values. It can be used under alkaline conditions, can withstand a certain degree of high temperature, is not easy to decompose or deteriorate, and is suitable for various complex water quality conditions and industrial production environments.
- Application Fields
- Water treatment field: In industrial circulating cooling water systems, boiler water systems, oilfield reinjection water systems, etc., it can prevent the dissolved salts in the water from scaling on the surface of equipment and pipelines, reduce the heat exchange efficiency, reduce equipment corrosion, prolong the service life of the equipment, and ensure the normal operation of the system.
- Petroleum industry: It is used for scale inhibition in oilfields to prevent blockage and corrosion problems caused by the deposition of salts such as calcium, magnesium, and barium in oil wells, oil pipelines, and water injection systems, ensuring the smooth progress of the oil extraction and transportation processes, and improving the productivity of oil wells and the efficiency of water injection.
- Detergent industry: As a washing aid, it can chelate metal ions in water, prevent the reaction between metal ions and the active ingredients in the detergent, improve the decontamination ability and cleaning effect of the detergent. At the same time, it can also prevent fabrics from yellowing or discoloring due to the presence of metal ions during the washing process.
- Other fields: It can be used as a stabilizer for peroxide bleaching. In the bleaching processes of industries such as textiles and papermaking, it can effectively inhibit the decomposition of peroxides and improve the bleaching effect and product quality. It can also be used in industries such as municipal industrial cleaning water, geothermal water treatment, papermaking, electroplating, metal pickling, and cosmetics, playing roles such as scale inhibition, chelation, and stabilization.
DTPMP·Na7 is usually packaged in plastic drums, with each drum being 30 kg or 250 kg, and it can also be determined according to the user's needs. It should be stored in a cool place indoors, and the storage period is ten months. During operation, attention should be paid to labor protection to avoid contact with the skin, eyes, etc. Once in contact, a large amount of clean water should be used for rinsing immediately.
