Structural Formula:

Properties:

TETHMP?Na12 has strong properties of scale and corrosion inhibition and high thermal stability, which decomposition temperature of dry product is 223 ~ 245 ℃. TETHMP?Na12 is easy to be degraded and safe to use.

TETHMP?Na12 is a strong complexing agent with high dissociation degree in water, and can form a stable complex with Ca2+、Mg2+ and other metal ions. TETHMP?Na12 can dissociate into twelve pairs of positive and negative ions in aqueous solution, chelate with two or more metal ions to form two or more complex of stereo macromolecule structure, loosely dispersed in water to destruct the normal crystalline of scale and prevent scale formation. TETHMP can effectively control the precipitation of carbonates, sulfates, phosphates, hydroxyl phosphates and ferric hydroxide and prevent the hard scale formation. In addition,TETHMP?Na12 can form stable adduct with active oxygen compound (e.g.H2O2, etc.) to keep stability of active oxygen.
