ABSTRACT:
Novel compositions are prepared by reacting methyl substituted nitrogen-containing aromatic heterocyclic compounds such as 2,5-dimethylpyrazine or 2,4,6-trimethylpyridine and an aldehyde such as 1-dodecanal or ketone such as 5,7-dimethyl-3,5,9-decatrien-2-one in the presence of a suitable catalyst such as zinc chloride. These novel compositions are useful as oil and gas well corrosion inhibitors.
