AminoTrimethylenePhosphonic Acid (ATMP) is a compound used in water treatment, primarily for preventing scale formation and reducing metal corrosion.

Basic Information of AminoTrimethylenePhosphonic Acid (ATMP)

  • Chemical Name: AminoTrimethylenePhosphonic Acid (ATMP)

  • CAS Number: 6419-19-8

  • Molecular Formula: N(CH2PO3H2)3 

  • Relative Molecular Mass: 299.05

Properties and Applications

ATMP possesses the following characteristics:

  • Good chelating ability

  • Low limit inhibition effect

  • Lattice distortion effect

  • Effectively prevents the formation of scale from water scaling salts, especially calcium carbonate scale

  • Chemically stable and not easily hydrolyzed in water

  • Has corrosion inhibition effects at higher concentrations

ATMP, or AminoTrimethylenePhosphonic Acid, is a versatile compound with a wide range of applications across various industries. Here's a brief overview of its uses in the mentioned fields:

  •  Circulating cooling water system

  • Oilfield injection water systems

  • As a metal ion chelant in the textile and dyeing industries

  • Metal surface treatment agents

In summary, ATMP is an effective chemical that provides significant benefits in various industrial applications by preventing scale formation, reducing corrosion, and improving the quality of processes and products.

Technical Indicators

The technical indicators of ATMP meet the standards HG/T2841-2005 and Q/SDTH0071—2019, including appearance, active component content, amino trimethylene phosphonic acid content, phosphorous acid content, phosphate content, pH value, density, chloride content, and iron content.

Usage Method

ATMP is typically blended with other organic phosphonic acids, polycarboxylic acids, or salts to form organic water treatment agents for use in various water quality conditions of circulating cooling water systems. The recommended dosage ranges from 1 to 20 mg/L; when used as a corrosion inhibitor, the dosage is 20 to 60 mg/L.

Packaging and Storage

  • Liquid ATMP is packaged in plastic drums, each containing 30kg or 250kg

  • Solid ATMP is packaged in plastic woven bags lined with polyethylene bags, each bag net weight 25kg, and can also be determined according to customer needs

  • Storage conditions are in a cool and ventilated indoor area, moisture-proof, and strictly avoid exposure to sunlight, with a shelf life of twelve months.

Safety Precautions

ATMP is acidic, and appropriate labor protection measures should be taken during operation to avoid contact with skin and eyes. In case of contact, rinse immediately with a large amount of clean water.
