stability
1. It can form a variety of stable complexes with a variety of metal ions and has stable chemical properties. It is not easy to decompose in strong acid-base medium. The decomposition temperature of dry product is 220 ~ 228℃. It is non-toxic and easily soluble in acidic solution. It has good scale inhibition and corrosion inhibition effect and good temperature resistance, and can inhibit the formation of carbonate and sulfate scale. In alkaline environment and high temperature (above 210℃), the scale and corrosion inhibition performance is better than other organic phosphines.
