Diethylenetriaminepenta -Methylenephosphonic Acid（DETPMP）
CAS No. 15827-60-8
Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2
Structural Formula:
Properties:
DETPMP is innocuous, easy to be dissolved in acid solution. DETPMP has excellent scale and corrosion inhibition and good thermal tolerance ability. DETPMP can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DETPMP has better scale and corrosion inhibition effect than other organophosphines.
Specification:
| Items | Index |
|---|---|
| Appearance | Brown transparent liquid |
| Active acid % | 50.0 min |
| Chloride (as Cl-)% | 12.0-17.0 |
| Density (20℃) g/cm3 | 1.35-1.45 |
| pH (1% water solution) | 2.0 max |
| Fe, mg/L | 35.0 max |
Usage:
DETPMP 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.
DETPMP 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, DETPMP is used in papermaking, electroplating, acid cleaning and cosmetics.
Package and Storage:
200L plastic drum,IBC(1000L),customers’ requirement. Storage for twelve months in shady room and dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted, flush with water.
