Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)
CAS No. *********8 Synonyms: Dequest
***0
Molecular Formula: C9H*8O*5N3P5
Molecular weight: **3.2
Structural Formula:
Properties:
DTPMPA is innocuous, easily to be dissolved in acid solution. It
has excellent scale and corrosion inhibition and good thermal
tolerance ability. It can inhibit the scale formation of carbonate,
sulfate and phosphate. On situation of alkali environment and high
temperature (above **0℃) it shows better scale and corrosion
inhibition effect than other organophosphates.
Specification:
| Items | Index |
| Appearance | Brown transparent liquid |
| Active acid % | *8.***2.0 |
| Phosphorous acid (as PO**- ) % | 5.0 max |
| Chloride (as Cl- ) % | ****7 |
| Density (*0℃) g/cm3 | 1.***1.*5 |
| pH (1% solution) | 2.0 max |
| Fe, mg/L | *5 max |
Usage:
DTPMPA 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.
DTPMPA can also be used as peroxide stabilizer, chelating agent in
woven dyeing industry, pigment dispersant, microelements carrying
agent in fertilizer and concrete modifier. In addition, it can be
used in papermaking, electroplating, acid cleaning and
cosmetics.
