Evaluation of a Non-Ionic Gemini Surfactant as Sweet Corrosion Inhibitor for X100 Steel in Sweet Brine Solution

In the present research work, evaluation of a non-ionic gemini surfactant derived from palm oil named bis(2-((2-palmitoamidoethyl) amino) ethyl) 1H-imidazole-4,5-dicarboxylate as an ecological corrosion inhibitor X100 steel immersed in NaCl solution at 3.5% saturated with carbon dioxide (CO 2 ) was analyzed. The electrochemical tests performed by Polarization Curves (PC) and Electrochemical Impedance Spectroscopy (EIS) showed that efficiency increased according to increase concentration inhibitor. Likewise, EIS results performance exposure time elapsed.
