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. It is identified by CAS 35657-77-3 and is widely used in industrial water and process chemical applications.

The compound functions by sequestering metal ions and inhibiting scale formation and corrosion in aggressive aqueous systems. Its sodium salt form is also commercially traded and sourced for formulated products requiring enhanced solubility.

In industrial water treatment, BHMT is formulated into scale and corrosion inhibitor packages for cooling water and boiler water. It is essential for oilfield injection systems where calcium carbonate and other mineral deposits are a persistent concern.

Oil and gas producers use it in produced water treatment and downhole chemical programs to prevent mineral scaling. This ensures the integrity of pipelines and wellbore equipment during demanding extraction and transport operations.

Textile and leather processors incorporate it into pretreatment baths to deactivate hardness ions. This prevents interference with dyeing uniformity and chemical uptake, ensuring high-quality finished goods in manufacturing cycles.

In paper manufacturing, it controls metal ion interference during pulp bleaching and process water recycling. This application helps maintain brightness and prevents the degradation of chemical additives during the production process.

BHMT is supplied as an aqueous solution, with the sodium salt form available for applications requiring improved handling. This version is preferred for solubility at neutral to alkaline pH levels in various industrial formulations.

Technical grade is the standard commercial specification for industrial end uses. Bulk supply is typical for water treatment chemical formulators and industrial blenders looking for reliable performance in large-scale systems.
