Penthedromethylene diethylene triamine phosphonate is an organophosphorus antiscalant. The molecular formula is C9H28O15N3P5 and the relative molecular weight is 573.2. Diethylenetriamine pentemethylene phosphate sodium is non-toxic, miscible with water, has good scale inhibition and corrosion inhibition effect, and has good temperature resistance, and can inhibit the formation of carbonate, sulfate and phosphate scale. Especially when the pH value is 10-11, calcium carbonate still has good scale inhibition performance, and the scale inhibition effect is 2 ~ 3 times higher than that of hydroxy-ethylene diphosphonic acid and aminotrimethylphosphonic acid. Another outstanding feature is that it has good corrosion inhibition ability for carbon steel and copper alloys in combination with manganese ions.
