IMIDAZOLINE BASED CORROSION INHIBITORS WHICH INHIBIT CORROSION CAUSED BY CO.SUB.2 AND H.SUB.2S

摘要

of the Invention The subject invention relates to corrosion inhibitors prepared by reacting certain imidazolines or precursors thereof with sulfur. The corrosion inhibitors are particularly useful in inhibiting corrosion of metal tanks caused by CO2 and H2S ("acid gas") during the transport and storage of crude oils.
