Chemische Eigenschaften
DTPMP is normally delivered as salts, because the acid form has very limited solubility in water and tends to crystallize in concentrated aqueous solutions. It is a nitrogenous organic polyphosphonic acid. It shows very good inhibition of the precipitation of barium sulfate (BaSO4). At high alkali and high temperature (above 210 °C) environments DTPMPA has better scale and corrosion inhibition effect than other phosphonates.
Verwenden
The phosphonate Diethylenetriaminepenta(methylenephosphonic acid) is a wastewater pollutant, and a component of phosphorous-containing nanoparticles and materials, such as in the preparation of chitosan nanoparticles for plutonium pulmonary decorporation.
Application
Water treatment formulations
Detergent & personal care product additive
Industrial & institutional cleaners
Oil field additive
Textile as peroxide bleach Stabilizer & leather auxiliary chemicals
Definition
Diethylenetriamine five methene phosphoric acid are a kind of widely used corrosion inhibiting and descaling agents, outward appearance is brown color or red-brown thick liquid, nontoxic, molecular formula is C9H28O15N3P5, relative molecular weight is 573.2, be soluble in acidic solution, can form polynary ring huge legendary turtle compound with metal ion in the aqueous solution, loosely is scattered in water, destroy the calcium salt crystalline growths such as carbonate, sulfate scale, thereby play scale effect, can suppress the generation of carbonate, sulfate scale.
Allgemeine Beschreibung
Diethylenetriaminepentakis(methylphosphonic acid) (DTPMP) is a multidentate chelating agent. Hydrogen peroxide oxidation of DTPMP is reported. DTPMP, a phosphonate, is commonly used as crystallization inhibitors.
Industrielle Verwendung
Under alkaline environment and high temperature, anticorrosion-antiscaling property is good.Diethylenetriamine five methene phosphoric acid are used as the anti-incrustation corrosion inhibitor of recirculated cooling water and feedwater in water treatment, be specially adapted to the anti-incrustation corrosion inhibitor of alkaline recirculated cooling water, and can be used for containing the high oil-field flooding of barium carbonate and the anti-incrustation corrosion inhibitor of water coolant, use separately this product in compound drug, without adding dispersion agent, the dirt deposition amount is still very little; This product also can be used as peroxide stabiliser, for textile printing and dyeing in the dispersion agent, oxygen delignification stablizer, chemical fertilizer of sequestrant, pigment trace element carry agent, concrete additive; In addition, at aspects such as papermaking, plating, metal pickling and makeup; Also can make the stablizer of oxidizing bactericide.
