Abstract: The disclosure provides compositions and methods for inhibiting corrosion of a copper surface using a bis-imidazoline compound having an aromatic group, such as an aryl bis-imidazoline. The bis-imidazoline corrosion inhibitor can provide one or more advantage in use such as synergistic performance in aqueous and acidic media at low active dosages, resistance to decomposition or degradation in the presence of harsh reagents, ease of dispersion in an aqueous system, and improved thermal stability over conventional triazole based inhibitors. The disclosure also provides methods for the synthesis of bis-imidazoline compounds.

Abstract: The present invention provides corrosion inhibiting compositions that incorporate at least one bis-imidazoline compound. In the practice of the present invention, a tetramine admixture enriched with respect to linear tetramine is used to prepare the bis-imidazoline compound. “Enriched” means at least 70 weight percent and up to 100% of the tetramine species included in the admixture includes a linear tetramine such as L-TETA.
