Adsorption of cationic Gemini surfactants on carbon steel surface and their anticorrosion performance in hydrochloric acid solution

AbstractMetal corrosion has hindered the advancement of new technologies. The surfactant as one kind of corrosion inhibitor can effectively restrain metal corrosion in corrosive medium. In this research, two cationic Gemini surfactants, 3,3′‐(ethane‐1,2‐diyl)bis(1‐octyl‐1H‐imidazol‐3‐ium) dibromide ([C8im‐2‐C8im]Br2) and 3,3′‐(butane‐1,4‐diyl)bis(1‐octyl‐1H‐imidazol‐3‐ium) dibromide ([C8im‐4‐C8im]Br2), have been prepared for the corrosion inhibition of carbon steels in 1.0 mol/L HCl solution. The weight loss measurement demonstrates that two inhibitors both achieve high inhibition efficiencyies at concentration of 0.50 mM for carbon steels in 1.0 mol/L HCl solution. By comparison, the anticorrosion performance of [C8im‐2‐C8im]Br2 for carbon steel specimens in 1.0 mol/L HCl solution are better than that of [C8im‐4‐C8im]Br2, and the maximum corrosion efficiency can reach 96.15% at the temperature of 30°C. The determination of adsorption thermodynamics and kinetics parameters reveals that the adsorption behavior of two inhibitors on the steel surface is chemisorption and follows Langmuir isotherm. Good anticorrosion performance of the inhibitor for carbon steel in HCl solution owes to a dense and compact protective film formed onto the steel surface. It indicates that the proposed cationic Gemini surfactants have great prospect in the corrosion inhibition of metals.

Essential oils extracted from two aromatic plants belonging to the Asteraceae family grown in Northern Algeria as green corrosion inhibitors for carbon steel

This paper investigates the corrosion inhibition properties of natural products, specifically essential oils extracted from the aerial parts of Artemisia judaica L. and Artemisia absinthium L., plants native to the City of Mostaganem, Northern Algeria. The essential oils were obtained through hydrodistillation and evaluated as corrosion inhibitors for steel in a 1 M HCl solution. Corrosion inhibition efficiency was assessed using weight loss measurements, potentiodynamic polarization, and electrochemical impedance spectroscopy. The results demonstrated that the inhibition efficiency increased with higher concentrations of essential oils, achieving maximum efficiencies of (94.84 ± 1.0055)% and (88.42 ± 1.8968)% at a concentration of 2.5 g L−1 for A. absinthium L. and Artemisia judaica L., respectively. Additionally, the influence of temperature on inhibition efficiency was examined, revealing a decline in performance with increasing medium temperature.

Synthesis and properties of a new environmentally friendly bicyclic imidazoline quaternary ammonium salt as a corrosion inhibitor of carbon steel

Abstract A new corrosion inhibitor, environment-friendly bicyclic imidazoline quaternary ammonium salt (DL-IM), was synthesized using DL-aspartic acid, hydroxyethyl ethylenediamine, and benzyl chloride as the main raw materials. The amidation, cyclization, and quaternization reactions were carried out at 140 °C for 4 h, 220 °C for 3 h, and 70 °C for 3 h, respectively. The structure of DL-IM was characterized by infrared spectroscopy and nuclear magnetic hydrogen spectroscopy. The corrosion experiments of carbon steel sheets (American Petroleum Institute, API 5CT N80, primarily used in well drilling operations to protect the wellbore), protected with or without DL-IM, demonstrated that DL-IM had a good anti-corrosion performance (with the inhibition efficiency and corrosion rate of 97.13% and 0.6528 mm/a, respectively) in the 1 M HCl solution at 60 °C. DL-IM was a kind of cathodic protection-type corrosion inhibitor confirmed by Tafel curves. The analysis of adsorption kinetics by quantum chemical simulations demonstrated that the imidazoline ring in the DL-IM molecule can form covalent bonds with the empty d-orbitals of Fe through charge sharing. Moreover, the dipole moment of DL-IM is 1.3931 D (1 D = 3.34×10-30 C·m), suggesting a good hydrophobicity of DL-IM. Therefore, the adsorption film formed by DL-IM on the surface of N80 can effectively isolate the corrosive medium from N80. Thus, successful synthesis of DL-IM provides a new insight into the design and synthesis of the environment-friendly corrosion inhibitor with stronger corrosion inhibition effect.

A detailed experimental and theoretical evaluations of two thiazolidine-2, 4-dione derivatives as corrosion inhibitors for carbon steel in a hydrochloric acid electrolyte

In this study, we conducted a comparative analysis of the inhibiting effect of two recently developed thiazolidine-2,4-dione derivatives, namely (Z)-3-allyl-5-(4-bromobenzylidene) thiazolidine-2,4-dione (TZD1) and (Z)-5-(4-bromobenzylidene) thiazolidine-2,4-dione (TZD2), on the corrosion protection of carbon steel (Csteel) in a 1 M HCl electrolyte. Both potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques were used to do this comparison. The results indicate that the concentrations of TZD1 and TZD2, as well as the experimental temperature, are important factors that affect inhibitory efficacy. At 303 K and a concentration of 10−3M, the highest significant inhibition rates were achieved, reaching 93.7% for TZD1 and 91.7% for TZD2. The PDP analysis revealed that TZD1 and TZD2 are mixed-type inhibitors that primarily function as anodic inhibitors. Using the Langmuir isotherm model as a guide, TZD1 and TZD2 molecules chemisorb onto the steel surface. Surface characterization analysis utilizing scanning electron microscopy (SEM), contact angle (CA), and X-ray diffraction (XRD) confirmed this interaction. Additionally, UV-visible spectra showed that TZD1 and TZD2 molecules interact significantly with Fe ions at certain atomic positions. To investigate how the molecular structure of TZD1 and TZD2 affects their ability to inhibit corrosion, Fukui functions, Molecular Dynamics Simulations (MDS), and DFT calculations were employed. An examination was also conducted to determine how the thiazolidine derivatives protonate in an acidic environment. Strong agreement was observed between the outcomes of these different approaches.

Experimental and computational studies of cationic Gemini surfactants as corrosion inhibitors for carbon steel in 15% HCl.

In the process of oil and gas exploration, the corrosion of carbon steel pipes results in substantial economic losses, numerous casualties, environmental contamination, and resource waste. The advancement of highly efficient and stable corrosion inhibitors holds significant importance for protecting carbon steel from corrosion during oil and gas exploitation. In this study, two new cationic Gemini surfactants (2CncoesT, where n = 12, 14) were synthesized through a straightforward two-step reaction. Weight-loss tests demonstrated that the inhibition efficiency (ηw%) increases with the increase in temperature. Specifically, the maximum ηw% values for 2C12coesT and 2C14coesT were 98.0% and 98.3% respectively at 85 °C. The adsorption of these surfactants conformed to the Langmuir adsorption isotherm. Electrochemical measurements suggested that the two surfactants functioned as mixed-type inhibitors. The findings obtained from scanning electron microscopy (SEM) were consistent with the experimental outcomes that 2C12coesT and 2C14coesT are efficient corrosion inhibitors for the metal in an acidic environment. The quantum chemical investigation and molecular dynamics simulation (MD) further substantiated the experimental results and offered insights for a deeper comprehension of the inhibition mechanism of Gemini surfactants.

Corrosion Inhibition of Carbon Steel Immersed in Standardized Reconstituted Geothermal Water and Individually Treated with Four New Biosourced Oxazoline Molecules

The current demand for heat production via geothermal energy is increasingly rising amid concerns surrounding non-renewable forms of energy. The Dogger aquifer in the Paris Basin (DAPB) in France produces saline geothermal waters (GWs), which are as hot as 70–85 °C, anaerobic, slightly acidic (pH 6.1–6.4), and characterized mainly by the presence of Cl−, SO42−, CO2/HCO3−, and H2S/HS−. These GWs are corrosive, and the casings of all geothermal wells are carbon steel. Since 1989, these GWs have been progressively treated using petrosourced organic corrosion inhibitors (PS–OCI) at the bottom of the production wells. Currently, there is a great need to test not only new PS–OCIs but also, and above all, biosourced organic corrosion inhibitors (BS–OCIs) to improve the efficiency and environmental friendliness of this carbon-free geothermal energy source. The main objective of this study is to evaluate the potential performance of biosourced corrosion inhibitor candidates (BS–CICs) in terms of their inhibition efficiency (IE) for carbon steel corrosion. This was achieved using a previously established geochemical and electrochemical method to study the mechanisms and kinetics of the corrosion/scaling of carbon steel and optimize short-term corrosion inhibition in standardized reconstituted geothermal water (SRGW) representative of the DAPB’s waters. Four new molecules from the 2-oxazoline family were evaluated individually and compared based on their behavior and inhibition efficiency. These molecules exhibited a mixed nature (i.e., anodic and cathodic inhibitors), with a slight anodic predominance, and showed a significant IE at a concentration of at 10 mg/L during the first hours of immersion of CS-XC38 in SRGW. The average IEs, obtained via the three electrochemical techniques used for the determination of corrosion current densities, i.e., Jcorr(Rp), Jcorr(Tafel), and Jcorr(Rw), are 51%, 79%, 96%, and 93% for Decenox (C10:1), Decanox (C10:0), Undecanox (C11:0), and Tridecanox (C13:0), respectively.

Corrosion inhibition potential of aqueous extract of Trifolium repens plant leaves on carbon steel in hydrochloric acid medium (TRPL)

This research explores the effectiveness of a liquid extract derived from the leaves of Trifolium repens as a corrosion inhibitor for carbon steel in a 1N hydrochloric acid environment. Corrosion poses significant challenges in industrial applications, and this study aims to provide an eco-friendly solution by leveraging plant extracts. The experiment demonstrated that the application of the Trifolium repens extract substantially reduced the weight loss of carbon steel, indicating its efficacy in mitigating corrosion. Inhibition efficiency was quantified through systematic weight loss measurements, revealing a clear inverse relationship between the concentration of the extract and the corrosion rate. As the concentration of the inhibitor increased, the rate of corrosion correspondingly decreased, underscoring the extract's potential for effective corrosion prevention. The mechanism of inhibition was further elucidated through electrochemical techniques. Potentiodynamic polarization (PDP) tests and alternating current impedance spectroscopy were employed to assess the electrochemical behaviour of carbon steel in the presence of the extract. These analyses confirmed the formation of a protective layer on the steel surface, which effectively blocks active corrosion sites, thereby enhancing the material's resistance to acidic attack. To gain deeper insights into the surface modifications caused by the inhibitor, the surface characteristics of the carbon steel samples were analysed using scanning electron microscopy (SEM). This technique allowed for the observation of differences in morphology between unprotected, corroded, and inhibited steel surfaces. Additionally, atomic force microscopy (AFM) was utilized to evaluate the roughness of the surface layer, providing quantitative data on the changes induced by the inhibition process. Overall, the findings indicate that the Trifolium repens extract not only acts as a potent corrosion inhibitor but also contributes to the formation of a protective barrier on carbon steel, thereby extending its lifespan in corrosive environments. This study highlights the potential for utilizing natural extracts as sustainable alternatives for corrosion prevention in industrial applications.

The Use of Some Natural Extracts as Environmentally Friendly Carbon Steel Corrosion Inhibitors

This paper presents the influence of natural extracts obtained from Levisticum officinale and Citrus x clementine on the corrosion of carbon steel in a 3.5% NaCl solution. We started from dried leaves of Levisticum officinale and Citrus x clementine peel in order to prepare several extracts in a 50%:50% (v:v) water/ethanol solution and in analytical-grade ethanol. Several electrochemical techniques, such as open circuit potential monitoring, electrochemical impedance spectroscopy and potentiodynamic polarization, were employed in order to investigate the influence of the synthetized extracts on the corrosion of carbon steel. The aggressive solution that the corrosion tests were performed in was a 3.5% NaCl solution modified with different amounts of the extracts. The electrochemical tests performed in order to determine the influence of the Levisticum officinale leaf and Citrus x clementine peel extracts showed that these extracts may be employed as natural corrosion inhibitors for carbon steel in a 3.5% NaCl solution, achieving inhibiting efficiencies up to 87.8%, in the case of the Levisticum officinale extracts.

The influence of temperature on the corrosion inhibition of carbon steel in HCl medium by bark resin of Schinus molle: electrochemical study

The purpose of this work is to investigate the effect of temperature (25 to 65 C°) on the adsorption and inhibition efficiency of Bark resin of Schinus molle for the corrosion of API 5L X70 pipeline steel in 0.5M HCl. Potentiodynamic polarization curves and electrochemical impedance spectroscopy were used to investigate the inhibition behavior of steel in HCl as a function of inhibitor concentration and temperature. The thermodynamic parameters of adsorption were estimated using adsorption theory. The results demonstrate that, at temperatures ranging from 25 to 65 degrees Celsius, bark resin of Schinus molle was an excellent inhibitor for API 5L X70 pipeline steel, with considerably steady inhibitory effectiveness. The greatest inhibitory effectiveness (93%) is achieved at 4 g/L. There is essentially no difference in the corrosion process between the lack and presence of BRSM, regardless of temperature. The adsorption of BRSM on steel surfaces is an exothermic reaction. BRSM adsorption includes physical adsorption. Bark resin of Schinus molle can be used as an environmentally friendly corrosion inhibitor for carbon steel in hydrochloric acid. The stability of BRSM inhibitory efficiency across a temperature range of 25 to 65 C° may find uses in acid pickling, industrial acid cleaning, and acid descaling.

Ricinus communis leaves extract as a green corrosion inhibitor for carbon steel in hydrochloric acid solution

The eco-friendliness of Ricinus communis leaves extract as an inhibitor for carbon steel (CS) corrosion was evaluated using weight loss (WL) as a chemical technique, and some electrochemical methods like AC electrochemical impedance spectroscopy (EIS), Tafel polarization (PP), and electrochemical frequency modulation (EFM). The data acquired showed that the higher the dose of the extract, the higher the protection efficiency (% IE), which increases with increasing temperature from 80.5 at 25 °C to 91.4 % at 45 °C. Using adsorption isotherms, adsorption factors were determined. Activation parameters were calculated and discussed based on Arrhenius and transition state principles. The adsorption procedure of Ricinus communis leaves extract on CS surface was found to be spontaneous and follows Langmuir's isotherm. This extract is a mixed type according to polarization data. Based on EIS data, it was shown that the extract of Ricinus communis leaves decreased the capacitance double layer (Cdl) from 539 to 74 μF cm−2 while enhancing the charge transfer resistance (Rct) from 70 to 430.5 Ω cm2. Surface analysis was done using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and atomic force microscopy (AFM) to measure the degree of surface roughness, film formation, and adsorbed groups on the CS surface. According to these tests, a layer of extract molecules forms on the CS surface.
