What is DTPMPA CAS 15827-60-8？
DTPMPA is non-toxic, easily soluble in acidic solution, has good scale inhibition and corrosion resistance and good temperature resistance, can inhibit the formation of carbonate and sulfate scale, and has better scale inhibition and corrosion inhibition performance than other organic phosphines in alkaline environment and high temperature (above 210℃). DTPMPA is used as a scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment, especially for alkaline circulating cooling water as a scale and corrosion inhibitor with irregular pH, and can be used as a scale and corrosion inhibitor for oil field water injection with high barium carbonate content, cooling water and boiler water. When this product is used alone in the compound agent, there is no need to add dispersant, and the amount of dirt deposition is still small.

Application
DTPMPA is used as a scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment, especially for alkaline circulating cooling water as a scale and corrosion inhibitor with irregular pH, and can be used as a scale and corrosion inhibitor for oil field water injection with high barium carbonate content, cooling water and boiler water. When this product is used alone in the compound agent, there is no need to add dispersant, and the amount of dirt deposition is still small. DTPMPA can be used as peroxide stabilizer, chelating agent for textile printing and dyeing, pigment dispersant, oxygen dellignification stabilizer, trace element carrier in chemical fertilizer, concrete additive. In addition, it has also been widely used in papermaking, electroplating, metal pickling and cosmetics. It can also be used as a stabilizer for oxidizing fungicides.
Packaging
