Abstract:  Gemini benzimidazole cationic surfactant, propanediyl-¦Á, ¦Ø-bis-(N-dodecyl benzimidazole ammonium bromide), referred as BIMGCS12-3, was synthesized from the raw materials of benzimidazole, dodecane bromide and dibromopropane. The structure of the target compound was confirmed by 1HNMR and elemental analysis. Electrochemical behaviors of BIMGCS12-3 for protecting mild steel from sulfuric acid corrosion were issued. Changes in impedance parameters (charge transfer resistance, Rct, and double layer capacitance, Cdl) were indicative of the feasibility of BIMGCS12-3 as excellent mild steel corrosion inhibitor in sulfuric acid.
