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.
