Abstract: Disclosed are methods of using biodegradable heterocyclic compounds of relatively low toxicity as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using compounds comprising a purine structure, and provides enhanced protection against corrosion of metals in aqueous systems. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising purine-based compounds are also disclosed.

Abstract: Disclosed are methods of using nitrogen-containing compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using 2-substituted imidazoles and 2-substituted benzimidazoles, and provides enhanced protection against corrosion of metals in the aqueous system. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising 2-substituted imidazoles and 2-substituted benzimidazoles are also disclosed.

Abstract: This disclosure relates to compositions and methods of reducing corrosion using benzimidazoles. The method may include adding a benzimidazole and a halogen to an aqueous system that is in contact with a metal surface. The halogen may be bromine, iodine, or any combination thereof. In some cases, adding the halogen may be optional depending on the substituents on the benzimidazole ring. Compositions are also disclosed that include a benzimidazole, optionally a halogen depending on the substituents on the benzimidazole ring, and optionally a halogen stabilizer.
