Abstract: The subject invention relates to compositions which inhibit the corrosion caused by CO2 and H2S in the transport and storage of crude oils, which are generally water-in-oil, in particular salt-water-in-oil emulsions. The corrosion inhibitors are mixtures of certain imidazoline or tetrahydropyrimidine derivatives, precursors thereof, or their complexes with sulfur and certain maleinamidic acids.
