Through the introduction of phosphonic group into carboxylic group, PCA/POCA have good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. They have good scale inhibition for barium sulfate, strontium sulfate and silica scale.
PCA/POCA have advantages in wide range of water quality, chemical stability, strong chlorine tolerance, etc. They can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
