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: The present disclosure relates to methods and compositions for making and using fluorescent monomers which are synthesized by reacting a substituted or non-substituted benzoxanthene anhydride with an amine and with a moiety containing a polymerizable group. Such monomers are useful for the preparation of tagged treatment polymers. Such tagged treatment polymers are useful as scale inhibitors in industrial water systems.

Abstract: Disclosed are nitrogen-containing heterocyclic compounds of relatively low aquatic toxicity and methods of using the heterocyclic compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using pyrazole derivatives, 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 pyrazole derivatives are also disclosed.

Abstract: Corrosion inhibitors and methods for reducing or inhibiting corrosion of metals in aqueous systems are provided. Corrosion inhibitor compositions may include tetracarboxylic acids, such as butane tetracarboxylic acid. The compositions may include other components, such as zinc, molybdate, silicate, cerium, among others. The compositions may also include polymers or oligomers. The corrosion inhibitor compositions produced synergistic results and unexpectedly low corrosion rates.
