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.
