Hydroxyethylamino-Di(Methylene Phosphonic Acid) (HEMPA)
Product description
| CAS No. | 5995-42-6 | EINECS No. | 227-833-4 | Molecular Weight | 249 Structural Formula |
Product Features
HEMPA is an organophosphoric acid, which exhibits excellent chelation, scale inhibition and corrosion inhibition. HEMPA is also compatible with methanol and water solution. When built together with other water treatment chemicals, HEMPA shows good synergistic effects. HEMPA is also an excellent dispersant for calcium-based deposits. HEMPA significantly improves the rinsing properties of washing and cleaning formulations. In high saline systems of oilfield applications, HEMPA can show its excellent calcium tolerance.
