DTPMP 50%
Diethylenetriamine Penta(methylene phosphonic acid) is the highest performance organophosphonate for preventing stubborn Barium Sulfate (BaSO₄) and Strontium Sulfate (SrSO₄) scale in oilfield waterflooding, pulp & paper mills, and industrial reverse osmosis.
Technical Specification Target
Barium & Strontium Sulfate Scale Prevention
Barium Sulfate is virtually insoluble in acid and cannot be removed mechanically once deposited inside oilfield downhole tubing or RO membrane channels. DTPMP functions as an extraordinary threshold scale inhibitor for BaSO₄ even at 2-5 ppm concentrations.
In paper peroxide bleaching baths, DTPMP stabilizes H₂O₂ far better than ordinary chelating agents by sequestering catalytic transition metal ions (Fe, Mn, Cu).
Standard Industrial Dosage

Frequently Asked Questions: DTPMP 50%
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is DTPMP 50% and what is its primary specialty?
DTPMP (CAS 15827-60-8) is a pentaphosphonic acid chelating scale inhibitor renowned as the industry gold standard for barium sulfate (BaSO₄) and strontium sulfate (SrSO₄) scale prevention.
Q2. What is the recommended dosing of DTPMP in oilfields and RO systems?
In oilfield downhole squeeze and produced water treatment, dosing is 10.0 to 30.0 ppm active. In high-sulfate RO feedwaters, dosing is 2.0 to 6.0 ppm active.
Q3. Why is DTPMP widely used in pulp and paper bleaching?
DTPMP has strong multi-dentate chelation that stabilizes hydrogen peroxide in pulp bleaching liquors (1.0 to 2.5 kg/ton pulp), increasing brightness and reducing chemical consumption.
