| Summary: | This research aims to convert tetraethylene pentamine Gemini surfactants from oil to water-soluble corrosion inhibitors for applying in oil field at temperatures up to 65 °C. To achieve this aim, four new ethoxylated Gemini surfactants denoted as (T1, T2, T4 and T6) bearing different ethylene oxide units of 19, 28, 45 and 65, respectively were prepared and evaluated as corrosion inhibitors. The chemical structures of the prepared inhibitors were verified using FT-IR and 1H NMR spectroscopic analysis. The performance of the prepared surfactants was determined using surface tension measurements and thermodynamic parameters. Weight loss and electrochemical measurements were utilized to measure their corrosion inhibition efficiencies at a temperature range of 25–65 °C. Through the obtained results, the maximum inhibition efficiency of 95.74% was obtained by T6 at 25 °C in 1 M HCl. Keywords: Surfactants, Gemini surfactants, Corrosion inhibitors, Weight loss |
