CAS No 15827-60-8 Dequest 2060
Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2
Structural Formula:
Properties:
DTPMPA is innocuous, easy to be dissolved
in acid solution. DTPMPA has excellent scale and corrosion inhibition
and good thermal tolerance ability. DTPMPA can inhibit the scale formation
of carbonate, sulfate and phosphate. On situation of alkali environment
and high temperature (above 210℃) DTPMPA has better scale and corrosion
inhibition effect than other organophosphines.

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, microelement’s carrying agent
in fertilizer and concrete modifier. In addition, DTPMPA is used in
papermaking, electroplating, acid cleaning and cosmetics.
Package and Storage:
Normally In 250kg net Plastic
Drum, IBC drum can also be used as required. Storage for ten months
in room shady and dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted, flush with
water.
