Abstract
In the present research work, the 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 of X100 steel immersed in NaCl solution at 3.5% saturated with carbon dioxide (CO2) was analyzed. The electrochemical tests performed by Polarization Curves (PC) and Electrochemical Impedance Spectroscopy (EIS) showed that the efficiency of the inhibitor increased according to the increase in the concentration of the inhibitor. Likewise, the EIS results showed that the inhibitor performance increased as the exposure time elapsed.
