    摘要: The disclosure relates to new surfactants of bis-N-alkyl polyether, bis-N-alkenyl polyether, bis-N-cycloalkyl polyether, bis-N-aryl polyether bis-beta or alpha-imino acids or their salts, process for obtaining and using mainly as multifunctional corrosion inhibitors, which protect and prevent corrosion of ferrous metals exposed to acidic, basic and neutral when transporting or storing crude oil and liquid fuels, or to the equipment and pipes used in cooling systems industry petroleum and petrochemical industries. Gemini surfactants have the structural formula: where: R1 is a radical represented by —H or —CH3, R2 is an alkyl or alkenyl chain, or cycloalkyl or aryl; R3 is a radical represented by —H, —CH3, —CH═CH—CH3, or —COOX; R4 is a radical represented by —H, —CH3, or —CH2—COOX; R5 is a radical represented by —H, an alkyl or alkenyl, cycloalkyl or aryl group, or a metal; R6 is a radical represented by an alkyl, alkenyl, cycloalkyl or aryl group; n and m can have values from 1 to 250, depending on the molecular weight of polyether used; and i can have values of 0 and 1: In the radical —COOX used in R3 and R4, X is represented by: —H, an alkyl, alkenyl group, a cycloalkyl or aryl group, or a metal.
