DTPMP
1.DTPMP (Diethylene Triamine Penta (Methylene Phosphonic Acid)
CAS No:15827-60-8
Molecular Weight:573.0
Molecular Formula:C9H28N3O15P5
Synonyms: Diethylenetriaminepenta(methylene Phosphonic acid)
2.Usage
ZEELCHEM™131 can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, and especially in alkali circulating cool water system without additional pH regulation, It can also be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used.
DTPMP can also be used as peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier. In addition, ZEELCHEM™131 is used in papermaking, electroplating, acid cleaning and cosmetics.
3.PROPERTIES
ZEELCHEM™131 is innocuous, easy to be dissolved in acid solution. ZEELCHEM™131 has excellent scale and corrosion inhibition and good thermal tolerance ability. ZEELCHEM™131 can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) ZEELCHEM™131 has better scale and corrosion inhibition effect than other organophosphines
