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.

Abstract: Oxalkylated polyamines containing amide groups which are suitable as demulsifiers for crude oil and are obtainable by condensation of dicarboxylic acids having 3 to 20 carbon atoms or functional derivatives thereof with polyalkylene-polyamines having at least 2 carbon atoms and at least 2 amino groups and reacting the reaction product with a total of from 1 to 200 mol/mol of ethylene oxide and/or propylene oxide and/or 1,2-butylene oxide.
