Basic Information
Product Name: Diethylenetriaminepenta(methylenephosphonic acid), abbreviated as DTPMPA
Molecular Formula: C9H25N3O15P5
Molecular Weight: 573.2
Appearance: Usually colorless to light yellow transparent or slightly yellow viscous liquid.
Odor: It has a slight ammonia smell.
Density: About 1.35 - 1.45 g/cm³ (at 20ºC).
Solubility: It is highly soluble in water and also soluble in organic solvents such as ethanol.
Stability: It has good chemical stability, remains stable within a wide pH range, and is resistant to hydrolysis and decomposition.
Product Uses
Water Treatment Agent: It is a highly efficient chelating - type scale and corrosion inhibitor. It can form stable complexes with metal ions such as calcium, magnesium, and iron in water, preventing the formation and deposition of scale. Meanwhile, it has a good corrosion - inhibition effect on metal surfaces and is widely used in the water treatment of industrial circulating cooling water systems, boiler water, oil - field injection water, and other systems.
Paper Industry: It is used as a scale inhibitor in the paper industry to prevent metal ions in the pulp from forming scale on the surface of paper - making equipment, which affects the quality of paper and the operation of equipment.
Textile and Dyeing Industry: In the textile and dyeing industry, it can be used as a metal - ion chelating agent to remove heavy metal ions in water, prevent their adverse effects on fabrics, and improve the dyeing effect.
Other Fields: It can also be used in metal cleaning, electroplating, cosmetics, and other fields as a metal - ion complexing agent and stabilizer.
Production Method
Generally, it is prepared by the reaction of diethylenetriamine with formaldehyde and phosphorous acid under certain conditions. During the reaction, the amino groups in diethylenetriamine undergo a condensation reaction with formaldehyde, and at the same time, the phosphorous acid reacts with the active groups in the condensation product through a phosphorylation reaction to form diethylenetriaminepenta(methylenephosphonic acid). The reaction is usually carried out under acidic conditions, and parameters such as reaction temperature, time, and the molar ratio of raw materials need to be controlled to achieve a high product yield and quality. After the reaction, the finished product is obtained through post - treatment processes such as neutralization, filtration, and concentration.
Packaging and Storage
Packaging: Usually packaged in plastic drums. Common packaging specifications include 25 kg and 200 kg. Other packaging forms can also be adopted according to customer requirements.
Storage: It should be stored in a cool, dry, and well - ventilated warehouse, away from direct sunlight and rain. Keep it away from fire sources and heat sources to prevent the product from decomposing due to heat. The storage temperature should generally not exceed 40ºC. During storage, prevent the packaging container from being damaged to avoid product leakage.
