EDTPMP - Nature
Open Data Verified Data
orange color with ammonia odor viscous liquid, can be miscible with water, can form a variety of stable complexes with a variety of metal ions, with stable chemical properties, it is also not easy to decompose in strong acid-base medium. The decomposition temperature of the dry product was 220-228 °c. Non-toxic, soluble in acidic solution, scale and corrosion inhibition effect and good temperature resistance, can inhibit the formation of carbonate, sulfate scale. In alkaline environment and high temperature (above 210 deg C), scale and corrosion inhibition performance is better than other organic phosphine.

EDTPMP - Preparation Method
Open Data Verified Data
The orange liquid can be obtained by the reaction of anhydrous diethylenetriamine, formaldehyde and phosphorus trichloride. This liquid can be used as a scale inhibitor for circulating cooling water. If the solid product is prepared, the liquid can be slowly dropped into anhydrous ethanol, that is, a white precipitate is precipitated, and the ethanol is filtered off, and the solid product is obtained.

EDTPMP - Application
Open Data Verified Data
The product is a Cathodic corrosion inhibitor, which can form a multiple ring chelate with metal ions, and is suitable for scale and corrosion inhibitors in alkaline circulating cooling water. Can also be used for hydrogen peroxide stabilizer, can also be used as metal cleaning agent to remove metal surface grease, also used as detergent additives, metal ion chelating agent, cyanide-free electroplating additives, precious metal extractant. With polycarboxylate, nitrite has good synergistic ability, and character distortion and low inhibition. When the concentration is less than 3 mg/L, the scale inhibition rate is more than 95%, especially in alkaline solution (pH 10~14), the calcium carbonate still has good scale inhibition performance.

EDTPMP - Safety
Open Data Verified Data
It has a stimulating effect on eyes and skin. Contact with eyes and skin should be avoided. Staff should be well protected, if accidentally touch the eyes and skin, should immediately rinse with plenty of water.

| Application | is suitable for use in alkaline circulating cooling water as an inhibitor of scale and corrosion without pH adjustment, and can be used for high barium carbonate oil field water injection and cooling water circulating cooling water and boiler water excellent corrosion and Scale Inhibitor, it is especially suitable for scale and corrosion inhibitors in closed-circuit circulation and alkaline circulation cooling water of power plant flushing water system as a non-PH adjustment, and can be used for scale and corrosion inhibitors in oil field water injection, cooling water and boiler water with high barium carbonate content, and stabilizers for peroxides and chlorine dioxide bactericides. The product is used alone in the compound agent, without adding a dispersant, and the amount of dirt is still very small. This product is used as a raw material for the synthesis of antibiotics in medicine, and the pesticide industry is used for the synthesis of highly efficient herbicides, it is also used as a raw material for the synthesis of organic chlorides DTPMPA in water treatment as a scale and corrosion inhibitor for circulating cooling water and boiler water, especially for alkaline circulating cooling water as a scale and corrosion inhibitor without adjusting pH, it can be used for scale and corrosion inhibitors of oil field water injection, cooling water and boiler water with high barium carbonate content. This product is used alone in the compound agent without adding dispersant, and the amount of dirt deposition is still very small. DTPMPA can also be used as peroxide stabilizer, chelating agent for textile printing and dyeing, pigment dispersant, oxygen delignification stabilizer, trace element carrier in fertilizer, concrete additive. In addition, it has been widely used in papermaking, electroplating, metal pickling and cosmetics. It can also be used as a stabilizer for oxidizing bactericides. |
