What is Bis(hexamethylene)triaminopenta(methylene-phosphonic acid)?
Bis(hexamethylene)triaminopenta(methylene-phosphonic acid), also known as BHMTPMPA or BHMT, is a high-performance phosphonate chelating agent (CAS 35657-77-3).
Where is Bis(hexamethylene)triaminopenta(methylene-phosphonic acid) used?
- Industrial water treatment: scale and corrosion inhibitor packages for cooling water and boiler water
- Oilfield injection systems: control of calcium carbonate and mineral deposits
- Oil and gas: produced water treatment and downhole chemical programs to prevent mineral scaling
- Textile and leather: pretreatment baths to deactivate hardness ions
- Paper manufacturing: control of metal ion interference during pulp bleaching and process water recycling
- It sequesters metal ions and inhibits scale formation and corrosion in aggressive aqueous systems.
Good to know: The sodium salt form is also commercially traded for formulated products requiring enhanced solubility; it is preferred for solubility at neutral to alkaline pH.
