摘要：
Gemini surfactants of bis-N-alkyl polyether, bis-N-alkenyl polyether, bis-N-cycloalkyl polyether, bis-N-aryl polyether bis-beta or alpha-amino acids or their salts, are produced for use as multifunctional corrosion inhibitors, which protect and prevent corrosion of ferrous metals exposed to acidic, basic and neutral liquids when transporting or storing crude oil and liquid fuels. The surfactants are also used to inhibit corrosion of equipment and pipes used in cooling systems in petroleum and petrochemical equipment. The Gemini surfactants have the structural formula:
