“…Furthermore, the smaller double layer capacitance, the better protection provided by an inhibitor. It is important to remark that all these compounds displayed corrosion inhibition efficiencies over 90% at rather low concentration values, which resulted even better than other types of corrosion inhibitors reported in the literature [30,[32][33][34][35][36][37][38][39]. All compounds studied in this work showed a corrosion inhibitive activity comparable at least or better than to other organic inhibitors derived from purine nucleobases (adenine and guanine) [53][54][55].…”

“…In the last years, the corrosion inhibition of steel in acid solutions by nitrogen-containing heterocyclic compounds has been extensively studied. In this regard, 1,2,4-triazole derivatives are considered to be effective acidic corrosion inhibitors [30][31][32][33][34]. Recently, some 1,2,3-triazole derivatives have been reported as a new class of corrosion inhibitors in acidic media [35][36][37][38][39].…”

A series of new mono-1,2,3-triazole derivatives of pyrimidine nucleobases were synthesized by one-pot copper(I)-catalyzed 1,3-dipolar cycloaddition reactions between N-1-propargyluracil and thymine, sodium azide and several benzyl halides. The desired heterocyclic compounds were obtained in good yields and characterized by NMR, IR, and high resolution mass spectrometry. These compounds were investigated as corrosion inhibitors for steel in 1 M HCl solution, using electrochemical impedance spectroscopy (EIS) technique. The results indicate that these heterocyclic compounds are promising acidic corrosion inhibitors for steel.

“…[18,28,32,33]. The higher E * a can be correlated with the increased thickness of the formed double layer, which increases the activation energy of the corrosion process [4,16,23,34]. The E * a values in the presence of Itraconazole and Fluconazole are nearly similar, suggesting that the two inhibitors inhibit the corrosion process with similar mechanisms.…”

“…This means the inhibitors reduce the corrosion current without causing considerable change in the corrosion mechanism. This means also that the addition of these inhibitors to the solution reduces the anodic dissolution and retards the cathodic hydrogen evolution reaction [4].…”

“…Li, John, and others [4][5][6] show that if the displacement in the corrosion potential is more than ±85 mV with respect to the blank, then the inhibitor is labeled as cathodic or anodic type; otherwise inhibitor is treated as a mixed type. In our study, the maximum displacement was 73 and 62 mV for Itraconazole and Fluconazole, respectively.…”

Corrosion inhibition and adsorption behavior of two triazole derivatives on API 5L-B carbon steel in CO 2 -saturated 3.5% NaCl solutions was investigated using potentiodynamic polarization, EIS, and EFM techniques. Specimen surfaces were characterized using SEM, EDX, and XRD. Results show that the two compounds are mixed-type inhibitors and inhibition efficiency increases with increasing concentrations. Adsorption of the two compounds chemisorption and obeys Langmuir adsorption isotherm. Activation energy and thermodynamic parameters were calculated. Surface analyses confirm the formation of iron nitrides on the metal surface which supports results obtained from previous techniques.

1-(6-Bromohexyloxy)-4-propargyloxybenzene upon quaternization with 3-dimethylamino-1-propanol and N,Ndimethyldodecylamine produced two new inhibitor molecules: N-[6-(4-Propargyloxyphenoxy)hexyl]-N,N-dimethyl-N-(3hydroxypropyl)ammonium bromide (PHAB) and N-[6-(4-Propargyloxyphenoxy)hexyl]-N,N-dimethyl-N-dodecylammonium bromide (PDAB), respectively, in excellent yields. The inhibitor molecules were characterized by elemental analysis, Fourier transform infrared spectroscopy, 1 H NMR, and 13 C NMR spectroscopy. The inhibitors were evaluated for X-60 mild steel corrosion in 15 wt.% HCl using different electrochemical and gravimetric techniques. The potentiodynamic polarization confirms both the inhibitors as mixed-type corrosion inhibitors. A low concentration (15 ppm) of PDAB has demonstrated excellent corrosion inhibition efficiencies of 97%, 98%, and 86% at 25°C, 50°C, and 70°C, respectively, for 24 h exposure time. SEM and EDX spectra reveal that the adsorptions of corrosion inhibitors on X-60 mild steel create a protective film that serves as a barrier to mitigate the corrosion process. The X-ray photoelectron spectroscopy confirmed the chemical interaction between the corrosion inhibitors and mild steel, which was predicted by the Langmuir adsorption model. Assembly of inhibitive motifs of the alkyne, π-electron-rich aromatic, quaternary ammonium and C 12 alkyl chain hydrophobe in PDAB has augmented its inhibiting action.
