“…The interaction between mild steel and inhibitor as well as the configuration of adsorption is further confirmed through molecular dynamic simulation and thereby inhibits corrosion on the surface of mild steel [28-30, 80, 81]. MPII showed comparable inhibition efficiency as compared to some other studied ionic liquids such as 1-ethyl-3methylimidazolium chloride (EMIm Cl) [82], 1-octyl-3-methyl imidazolium chloride [83], 3-(4-ethoxy-4oxobutyl)-1-ethylimidazol-3-ium bromide [84], 1-(4-sulfobutyl)-3-methylimidazolium hydrogen sulphate [85] and N,N-dimethyl-N-dodecyl-Nethyl-ammonium ethyl sulfate [86] having almost same order of inhibition efficiencies for corrosion inhibition for mild steel.…”

Corrosion inhibitive property of ionic liquid 1-Methyl-3-propylimidazolium iodide (MPII) on Mild Steel in 1 M H 2 SO 4 was investigated by experimental and computational Studies. The inhibition efficiency of inhibitor MPII at various concentrations, temperature and time duration were studied by gravimetric measurements, potentiodynamic polarization techniques, electrochemical impedance spectroscopy (EIS), surface studies and computational studies. The results from potentiodynamic polarization studies revealed that inhibitor 1-Methyl-3-propylimidazolium iodide acts as a mixed type inhibitor with a high inhibition efficiency of 91% at 298 K. Adsorption of the inhibitor on the surface of mild steel follows the Langmuir adsorption isotherm. The mechanism of adsorption was also validated by quantum chemical studies. Morphology and topography of the Mild Steel surface with and without the inhibitor were investigated by SEM. Thermodynamic parameters for adsorption like adsorption equilibrium (K ads ), DH , ads DS , ads Free energy of adsorption i.e. ΔG ads were also calculated so as to project the mechanism of adsorption. Computational data obtained from the Density functional theory (DFT) were used to acquire detailed theoretical insights. Appreciably Electrochemical impedance spectroscopy, Molecular dynamic simulation and quantum chemical calculation confirms the interaction of inhibitor with metal which leads to increases in inhibition efficiency.

“…For the evaluation of the PILs as CIs in an acid medium, the working electrodes (WEs) were previously prepared using API 5L X60 steel samples with the following chemical composition: C (0.14%), Mn (1.04%), Si (0.25%), Cr (0.07%), Mo (0.08%), V (0.03%), Cu (0.03%), Ni (0.05%), Al (0.026%), P (0.014%), S (0.011%), Ti (0.015%), Nb (0.001%), and Fe (balance). 105 The WE had exposed surface areas of 0.2894 cm 2 . Before each experiment, such a surface was abraded with SiC sheets with grades from 600 to 1200; afterward, the material was rinsed with distilled water and ethanol, drying it with nitrogen at ambient temperature.…”

A corrosion inhibition mechanism of API 5L X60 steel exposed to 1.0 M H 2 SO 4 was proposed from the evaluation of three vinylalkylimidazolium poly(ionic liquids) (PILs), employing electrochemical and surface analysis techniques. The synthesized PILs were classified as mixed-type inhibitors whose surface adsorption was promoted mainly by bromide and imidazolate ions, which along with vinylimidazolium cations exerted a resistive effect driven by a charge transfer process by means of a protective PIL film with maximal efficiency of 85% at 175 ppm; the steel surface displayed less surface damage due to the formation of metal−PIL complex compounds.

Five fatty acid-based ionic liquids (FAILs) with various anionic alkyl chain lengths are synthesized, namely methyltrioctylammonium butyrate ([N 8881 ][C 4:0 ]), methyltrioctylammonium caproate ([N 8881 ][C 6:0 ]), methyltrioctylammonium octanoate ([N 8881 ][C 8:0 ]), methyltrioctylammonium laurate ([N 8881 ]-[C 12:0 ]), and methyltrioctylammonium palmitate ([N 8881 ][C 16:0 ]), to investigate the potential effects of anionic alkyl chains on their corrosion inhibition property for mild steel in 1 M HCl solution via X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, contact angle measurements, electrochemical measurements, and weight loss measurements. The results reflect that the FAIL inhibitor can adsorb on the surface of mild steel to form a protective film and effectively inhibit the corrosion. [N 8881 ][C 8:0 ] exhibits the optimal inhibition efficiency (96.94%) in comparison to [N 8881 ][C 4:0 ] (80.73%), [N 8881 ][C 6:0 ] (89.34%), [N 8881 ][C 12:0 ] (90.69%), and [N 8881 ][C 16:0 ] (74.42%).It is speculated that the varied anionic alkyl chain length may change the intensity of the protective film to affect the inhibition efficiency. The in-depth analysis by molecular dynamic simulation confirms that [N 8881 ][C 8:0 ] with the same anionic and cationic alkyl chain lengths shows the most ordered and compact film on the mild steel surface. The present study focuses on the effects of the anionic alkyl chain on the corrosion inhibition performance and provides novel insights into the design and development of effective and eco-friendly ionic liquids as corrosion inhibitors.
