Abstract
The ionic liquid namely 3-((4-amino-2-methylpyrimidin-5-yl)methyl)-5-(2-hydroxyethyl)-4-methylthiazol-3-ium chloride (AMPMHMC) was used as a corrosion inhibitor to protect carbon steel against 1 M HCl solution. The corrosion behavior was investigated by chemical and electrochemical techniques. The results showed that the inhibition efficiency increased with increase in the concentration (10–40 ppm) of the inhibitor and the maximum inhibition efficiency reached 91.4% at concentration 40 ppm. The adsorption of the inhibitor on carbon steel surface obeyed the Langmuir’s adsorption isotherm. Surface analysis of the carbon steel was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results further demonstrated that the AMPMHMC was a promising environment-friendly inhibitor with effective inhibition efficiency.
