Abstract
This invention relates to water-soluble corrosion inhibiting compositions and the method of making the same. Specifically, this invention relates to inhibiting the corrosion of metals, particularly those employed in the production, processing, and transportation of petrochemical products. These water-soluble corrosion inhibiting compositions are created by neutralizing a C.sub.22 tricarboxylic acid with aminoethylethanolamine and a member selected from the group consisting of imidazoline, amidoamine, and combinations thereof. The resulting compositions exhibit excellent film persistency characteristics even when utilized in small amounts.
