Molecular formula C17H44O15N3P5
Relative molecular mass: 685
Structural formula
Ⅰ. Performance and use:
BHMTPMPA is an effective chelating scale inhibitor with good scale inhibition effect on carbonate scale and sulfate scale. Bmtpmpa has excellent water solubility, thermal stability and high tolerance of calcium ions in a wide PH range and at 120℃. Bmtpmpa is used as corrosion inhibitor and scale inhibitor for oil field water treatment, industrial circulating cooling water and boiler water.
