MolecularFormula: C9H28N3O15P5 

CommercialForm: Aqueous Solution

MolecularWeight:573

ChemicalName: Diethylenetriamine penta(methylenephosphonic acid)

CASNumber:15827-60-8

ApplicationNotes: Good general purpose scaleinhibitor. Powerful sequestrant. Second best against BaSO4.DTPMPA isinnocuous, easy to be dissolved in acid solution. DTPMPA has excellentscale and corrosion inhibition and good thermal tolerance ability.DTPMPA caninhibit the scale formation of carbonate, sulfate and phosphate. onsituation of alkali environment and high temperature (above210°C) DTPMPA has betterscale and corrosion inhibition effect than otherorganophosphines.

RecommendedUses:DTPMPAcan be used as scale and corrosion

inhibitor incirculating cool water system and boiler water, and especially inalkali circulating cool water system without additional pHregulation, It can also be used in oilfield refill water, coolwater and boiler water with high concentration of barium carbonate.When used alone, little scale sediment is found even none ofdispersant is used.

DTPMPA can also beused as peroxide stabilizer, chelating agent in woven & dyeingindustry, pigment dispersant, microelement’s carrying agent infertilizer and concrete modifier. In addition, DTPMPA is used inpapermaking, electroplating, acid cleaning andcosmetics.
