Resumen:
In the present investigation a novel non-ionic gemini surfactant, namely bis(2-((2-palmitoamidoetil) amino) etil) 1H-imidazol-4,5-dicarboxilate, was synthesized from the fatty acids contained in the palm oil and evaluated as corrosion inhibitor for UNS S41425 type supermartensitic stainless steel in a sour solution. The obtained results from electrochemical techniques showed that, the inhibition efficiency increased with increase of the inhibitor concentration. The maximum inhibition efficiency was reached 99% at 100 ppm. The potentiodynamic polarization measurements indicated that the gemini surfactant acts as anodic type inhibitor. The adsorption of the inhibitor on the UNS S41425 surface in the sour solution was found to obey Langmuir’s adsorption isotherm. © The Electrochemical Society.
