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.
