Phosphonate polycarboxylic acid is typically synthesized by a reaction between a phosphonic acid and a carboxylic acid in the presence of a suitable catalyst. This can be achieved using a variety of methods, including conventional heating, microwave irradiation, or ultrasonic irradiation. The reaction typically proceeds via a condensation reaction between the phosphonic acid and the carboxylic acid, leading to the formation of a polymer with phosphonate and carboxylate functional groups. The resulting phosphonate polycarboxylic acid is widely used in various industrial and agricultural applications due to its excellent chelating properties and ability to sequester metal ions.

Frequently Asked Questions

What is TH-164 used for?
TH-164 has good dispersibility for calcium carbonate and calcium phosphate scale in circulating cooling water system. It has good scale inhibition effect on barium sulfate, strontium sulfate and silicon scale. TH-164 has the advantages of strong thermal stability and chlorine resistance. TH-164 can be used as scale and corrosion inhibitor in circulating cooling water system and oilfield reinjection water system. TH-164 has better performance than acrylate products in paper mills, ceramic industry, etc. It can also be used to disperse scale in boilers.
