Effects of Polyphenol Polymers on Corrosion of Mild Steel in Boiler Systems under Alkaline Conditions

To obtain an environmentally-compatible corrosion inhibitor similar to tannic acid, three varieties of polyphenol polymers, poly (caffeic acid), poly (caffeic acid-co-sodium styrene sulfonate) and poly (caffeic acid-coacrylic acid), were synthesized. The effects of polyphenol polymers on the corrosi...

Summary:To obtain an environmentally-compatible corrosion inhibitor similar to tannic acid, three varieties of polyphenol polymers, poly (caffeic acid), poly (caffeic acid-co-sodium styrene sulfonate) and poly (caffeic acid-coacrylic acid), were synthesized. The effects of polyphenol polymers on the corrosion of mild steel in boiler systems under alkaline conditions have been investigated. These polymers are able to inhibit corrosion due to the Schikorr reaction. In particular, two copolymers inhibit the corrosion of mild steel in the same manner as tannic acid.
