“…The position of propyl and butyl groups in IL1 and IL2 structures were designed to make a distant orientation between the carbon steel surface and corrosion agents. Under certain conditions, the addition of hydrophobic groups can improve corrosion inhibition performance through the process of preventing interactions between water molecules and electrolyte solutions from carbon steel surfaces [8,15,40,41].…”

“…Polar functional groups are considered as the reaction centers for the establishment of the adsorption process between corrosion inhibitors and carbon steel surfaces. However, the corrosion inhibitor is expensive, volatile, toxic, and unstable at high temperatures [14,15]. Therefore, the recent focus of research is to make environmentally friendly corrosion inhibitors, which have a low environmental risk.…”

“…Therefore, the recent focus of research is to make environmentally friendly corrosion inhibitors, which have a low environmental risk. The use of an organic compound is one of the best candidates as a raw material to make environmentally friendly corrosion inhibitors [4,[6][7][8][9][10][11][12][13][14][15][16][17][18]]. An organic compound-based corrosion inhibitor has several advantages, such as being environmentally friendly, relatively inexpensive, and having more effective inhibitor performance [19,20].…”

In this study, imidazole derivative-based new ionic liquids were investigated as corrosion inhibitors. These new ionic liquids (ILs) are 1,3-dipropyl-2-(2-propoxyphenyl)-4,5-diphenylimidazole iodide (IL1) and 1,3-dibutyl-2-(2-butoxyphenyl)-4,5-diphenylimidazole iodide (IL2). The corrosion inhibition effects of two new ILs were observed on carbon steel in brackish water media (1% NaCl solution). Carbon steel coupons were exposed to 1% NaCl solution with various concentrations of ILs. Corrosion inhibition effects were tested by the electrochemical impedance spectroscopy (EIS) method and the Tafel method at various temperatures ranging from 25 °C to 55 °C. The results showed that ILs have potential as corrosion inhibitors and the adsorption mechanisms of IL1 and IL2 on carbon steel surfaces were also determined, which followed the Langmuir adsorption isotherm model. Acquisition of ∆Gads values of IL1 and IL2 were −35.04 and −34.04 kJ/mol, respectively. The thermodynamic data of the ILs show that semi-chemical and or physical adsorptions occurred on carbon steel surfaces.
