“…Scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) are useful techniques used to detect and analyze the morphology and elemental composition of the Q235 steel surface in different situations. , The SEM and EDS graphs of Q235 steel immersed in 1 M HCl solution without or with 1 mM [1,8-Nap][CETSA] for 24 h at 35 °C are presented in Figure . In Figure a, the freshly polished mechanical marks on the surface of the carbon steel can be observed.…”

A several of basic ionic liquids (ILs) were synthesized as green solvents and catalysts for the preparation of 1,8-naphthyridyl derivatives via the Friedlander reaction. [Bmmim][Im] exhibited remarkable catalytic activity to achieve the synthetic targets, and the reaction conditions were optimized. The model product 2,3-diphenyl-1,8-naphthyridine (1,8-Nap), with carboxyethylthiosuccinic acid (CETSA) to form an IL corrosion inhibitor ([1,8-Nap][CETSA]), and its corrosion inhibition performance for Q235 steel in 1 M HCl were researched by weight loss measurements, and the results showed that the inhibition efficiency was 96.95% when the concentration of [1,8-Nap][CETSA] was 1 mM at 35 °C. The electrochemical test verified that [1,8-Nap][CETSA] acted as a mixed-type inhibitor but mainly exhibited cathodic behavior. The inhibitor adsorbed on the metal surface was further proved by surface topography analysis.

“…They can be used in transportation, construction, energy, and industries owing to their economic efficiency and strong versatility. , Heteroatoms (such as N, O, P, and S), heterocycles, multiple bonds, and aromatic rings are the most important electron-rich groups in the structure of organic CIs that cause the adsorption of their molecules on the surface of metal and protect it against corrosive species in the medium. ,− In other words, the replacement of CIs with water molecules on the metal surface leads to the blocking of active sites for redox reactions and thus inhibits the transfer of water and corrosive ions on the metal surface. , The molecular properties of CI molecules, such as steric factors, aromaticity, chain length, functional groups, electronic structures, cross-linking ability, and solubility have a significant impact on their adsorption behavior . Due to the low biodegradability of traditional CIs such as mercury salts, chromate, phosphorus-containing compounds, and the majority of organic molecules, it is critical to develop new eco-friendly inhibitors. − In recent years, CIs based on bio-sources such as carbohydrates, vegetable oils, amino acids, and plant extracts have been studied to address this issue. ,− Furfuryl alcohol as another renewable substance derived from furfural has also been investigated as a CI in acidic solutions. − Although the inhibition performance of bio-based CIs has been evaluated for corrosion inhibition of various metals, their main challenge is poor inhibition efficiency at high temperatures. , It should be noted that the temperature is over 353 K during some acid stimulation operations, which considerably increases the corrosive potential of the environment toward technological structures based on steel. In such conditions, the corrosion rate of steel accelerates dramatically, making operations impractical. , As a result, metals in the oil and gas industry must be protected against high-temperature acid corrosion by developing effective inhibitors.…”

Although corrosion inhibitors are widely used as a practical method for inhibiting metal corrosion in a variety of industries, their efficiency decreases dramatically at high temperatures. We present a thorough experimental and theoretical investigation into the inhibitory power of a novel thermally stable corrosion inhibitor based on furfuryl alcohol (FACI). The opencircuit potential, linear polarization resistance, potentiodynamic polarization, and electrochemical impedance spectroscopy techniques were used for the first time to evaluate FACI inhibition performance at 293, 313, 333, and 353 K. All electrochemical methods clearly indicated that FACI effectively suppressed corrosion of mild steel (MS) in the 15% HCl environment via a mixed-type mechanism at all temperatures investigated. The highest inhibition efficiencies of 95.4 and 90.8 at 333 and 353 K, respectively, were obtained in the solution containing 136 × 10 −5 M FACI. FACI inhibited both the anodic and cathodic corrosion reactions of MS, but its main effect was on the cathodic hydrogen evolutions. The results of the Langmuir adsorption isotherm confirmed that the predominantly chemical adsorption of FACI molecules occurred on the MS surface. The experimental results were also validated using a combined DFT.

The inhibitory activity of the expired egg-white carbon steel (CS) extract in HCl solution was studied in this article. The extract was examined using FT-IR, and the surface was examined using a scanning electron microscope (SEM) and energy-dispersive X-ray analysis (EDX). Weight loss techniques at various temperatures were used to examine corrosion investigations (298, 308, 318, and 328 K), concentrations (100, 200, 400, and 800 mg. L−1) of extracts, and electrochemical measurements (potentiodynamic polarization (PDP) and impedance spectroscopy (EIS) at 25°C and different concentrations. Results. Results obtained through EIS demonstrated a maximal inhibition efficiency of 90% at an inhibitor concentration of 800 mg. L−1. Moreover, the findings of the potentiodynamic polarization indicated that egg-white extract was a mixed type of inhibitor and slowed down both cathodic and anodic reactions. For weight loss analysis, an inhibitory potency (89, 83, 77, and 71%) at various temperatures (298, 308, 318, and 328 K) was demonstrated, respectively. It indicates that the temperature rise contributes to a decrease in the resistance of the carbon steel. The adsorption of the expired egg-white extract was spontaneous with physisorption and chemisorption according to the Langmuir isotherm model, according to adsorption isotherm studies.
