Posted on October 20, 2023October 20, 2023 By admin No Comments on Hydroxyethylamino-Di(Methylene Phosphonic Acid) (HEMPA)

CAS No. 5995-42-6                                Molecular weight: 249

Structural Formula:

Properties:

HEMPA is an organophophoric acid, which exhibits excellent chelation, scale inhibition and corrosion inhibition. It is mainly used in oilfield, detergent / soap and metal treatment etc, especially useful in the water sytems with high level of dissolved iron and calcium. It is also compatible with methanol/water solution. When built together with other water treatment chemicals, it shows good synergistic effects.

Specification:

Items Index Index
Appearance Colorless to light yellow transparent liquid Colorless to light yellow transparent liquid
Active content, % 50.0 min 60.0 min
pH (1% water solution) 2.0 max 2.0 max
Chloride (as Cl–), % 5.0 max 5.0 max
Fe, mg/L 20.0 max 20.0 max
Density (20℃), g/cm3 1.20 min 1.30 min

Usage:

HEMPA is usually used together with other organophosphoric acid, polycarboxylic acid and salt in different areas.

Package and Storage:

250kg/drum; 1250kg/IBC; or customers’ requirement. Storage for ten months in shady room and dry place.

Safety Protection:

Avoid contact with eye and skin. Goggles and rubber gloves should be used at all times while handling the product.
