Molecular Formula: C9H28O15N3P5
Molecular weight: 573.2
Structural Formula:
Product performance:
DTPMPA is innocuous, and easily to be dissolved in acid solution. It has excellent scale and corrosion inhibition and good thermal tolerance ability. It can also inhibit the scale formation of carbonate, sulfate and phosphate. The scale and corrosion inhibition is better than those of other organic phosphonic acids under the alkali environment and high temperature (above 210℃). DTPMPA has high calcium solubility, when the PH value=10-11, the corrosion inhibitor is obvious superior than ATMP, the corrosion ability is 2 to 3 times than that of ATMP、HEDP, and it have good corrosion effect on barium sulfate.

Range of application:
DTPMPA can be used as scale and corrosion inhibitor in circulating cooling water systems and boiler water, and especially in alkali circulating cooling water systems without additional PH regulation. It can also be used as scale and corrosion inhibitor in oilfield water injection、cooling water and boiler water which has high barium sulfate.
DTPMPA can also be used as peroxide stabilizer, chelating agent in textile dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete additives. In addition, DTPMPA is widespread used in papermaking, electroplating, acid cleaning and cosmetics, can also be used as stabilization of oxidability bactericide.
Usage:
DTPMPA is used together with organic phosphorous、carbazole and other water treatment chemicals, there is no need to add dispersant agent when use DTPMPA in formulation medicament, the dirt deposition is very small.
Package and Storage:
Normally In 30kg net Plastic Drum, IBC drum can also be used as required.
Storage for ten months in room shady and dry place.
