Hydroxyethylamino-Di(Methylene Phosphonic Acid) (HEMPA)

CAS No. 5995-42-6

Molecular weight: 249.1

Structural Formula:

Features:

1. Chelation: HEMPA exhibits powerful chelating properties, which allow it to bind tightly with metal ions, thereby preventing the formation of unwanted precipitates and scaling. This feature makes it an ideal choice for water treatment plants and boilers.

2. Scale Inhibition: One of the primary issues faced in water systems is scaling, which is caused due to the accumulation of mineral deposits. HEMPA effectively prevents scaling by stabilizing the calcium and iron ions, making it an essential component for water treatment applications.

3. Corrosion Inhibition: HEMPA acts as an efficient corrosion inhibitor by forming a protective barrier on the surface of metals, thereby preventing them from reacting with oxygen and other corrosive species. This helps in prolonging the life of metals and reducing overall maintenance costs.

4. Compatibility: HEMPA is highly compatible with methanol/water solutions, allowing it to be easily incorporated into various formulations. This feature makes the compound highly adaptable for a wide range of applications.

5. Synergistic Effects: When formulated together with other water treatment chemicals, HEMPA demonstrates remarkable synergistic effects, resulting in enhanced performance and efficiency.
