Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMP)
CAS No: 15827-60-8
Molecular Formula: C9H28O15N3P5
Structural Formula:
Use
This product is excellent corrosion - scale inhibitor for cyclic cooling water and boiler water. It is particularly suitable to be used in base cyclic cooling water as not-changing pH scale - corrosion inhibitor and can be used as scale - corrosion inhibitor in oilfield filling water, cooling water, boiler water which has high barium carbonate content. It also can be used as stablizer of germicide of chlorine dioxide. The scale deposition would be still very little even if using this product alone without adding dispersant.
Characteristic
This product is water-soluable. It has good effect of scale inhibiting to calcium sulfate, calcium carbonate and barium sulfate; especially to calcium carbonate even though in base solution (PH 10~11). It take on two unique performances:
(1). Although in base solution (PH10-11), it yet keep good effect of scale inhibiting to calcium carbonate which is 1~2 times higher than that of HEDP, ATMP.
(2). It has good effect of scale inhibiting to barium sulfate.
(3). It has better effect of corrosion inhibiting than HEDP, ATMP.
(4). It is stablizer of germicide of chlorine dioxide.
