Abstract
Novel compositions are prepared by reacting hydrocarbyl substituted nitrogen-containing aromatic heterocyclic compounds such as 2,5-dimethylpyridine or 2,4,6-collidine, an aldehyde such as formaldehyde, or a ketone such as acetone, or mixtures thereof and an amine having a combined total of at least seven carbon, nitrogen, oxygen or sulfur atoms and at least one reactive amine hydrogen atom such as 1-dodecanamine in the presence of a suitable catalyst such as hydrogen chloride. These novel compositions, as well as their free amine forms are useful as oil and gas well corrosion inhibitors.
