“…tested mixtures with different ratios of isononylphenolethoxyphosphoric esters and monoethanolamine in a water‐isopropanol solution as CIs for St3 steel immersed in CO 2 ‐saturated 3 wt.% NaCl solution, at 20 °C. Moreover, terephthaloyl salicylidene dihydrazone and its complexes with VO 2+ and Ni 2+ were tested as CIs for steel immersed in CO 2 ‐saturated 3.5 wt.% NaCl solution, at 50 °C [139] …”

“…The studies reporting on the corrosion inhibition of these compounds were conducted for steel samples immersed for 1 h–20 days in either CO 2 ‐saturated NaCl solution/brine, [42a,43,79h,j,88e,137–139] or CO 2 ‐saturated simulated oilfield waters, [45b,c,86,108,131e] in a temperature range from room temperature to 80 °C. The corrosion inhibition of 4,6‐diamino‐2‐(benzylthio)pyrimidine was investigated for N80 steel immersed in CO 2 ‐saturated simulated oilfield water [86] with 8 MPa CO 2 partial pressure.…”

This review paper discusses the research work published in the last decade on the use of organic compounds and natural products as corrosion inhibitors for steel in CO2 and CO2/H2S coexisting environments. The carbon and mild steel samples tested are mostly immersed in CO2‐saturated NaCl/brine solutions or simulated oilfield waters. The influence of temperature, immersion time, CO2 partial pressure, pre‐corrosion, flow rate/rotation speed, and the synergistic effect of other compounds on the corrosion inhibition effectiveness of organic compounds and natural products is presented. Primarily, weight loss and electrochemical techniques were used to evaluate the corrosion inhibition effectiveness of these compounds.

Seven homo-bimetallic complexes derived from 3-(-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)methylene)hydrazono)indolin-2-one with Fe 3+ , Co 2+ , Cu 2+ , and UO 2 2+ have been prepared and structurally investigated using elemental and thermo-gravimetric analyses and spectral, magnetic, and molar conductivity measurements. This structural investigation leads us to conclude that the bis-hydrazone has behaved as neutral tetradentate chelator chelated to the Fe 3+ , Co 2+ , Cu 2+ , and UO 2 2+ ions via the carbonyl and azomethine groups adopting distorted octahedral structure for Fe 3+ , Co 2+ , and Cu 2+ complexes (2-5), whereas the Cu 2+ complexes (6-7) have square planar structures. The structural characterization of bis-hydrazone and its chelated compounds has been supported by density functional theory calculations. The optimized geometry, global reactivity descriptors, and lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) of the molecules have been calculated in accordance with the density functional theory (DFT)-Beckee3eLeeeYangeParr (B3LYP) technique and 6e311G(d,p) basis set. The molecular electrostatic potential image was also drawn by the DFT-B3LYP technique and 6e311G(d,p) basis set to envision the charge distribution and chemical reactivity on the molecules. The bioeffect of bis-hydrazone and its chelated compounds was assessed against bacterial strains Bacillus subtilis, Escherichia coli, as well as fungal strains Canadian albicans and Aspergillus niger. The observed data imply encouraging bioeffect of some of these complexes in comparing with the free bis-hydrazone or amphotericin B (AmB) against all fungal C. albicans and A. niger.

N‐Salicylidene amino acid Schiff base sodium sulfonate salt, as a tridentate dibasic chelating ligand, was obtained from the common condensation of salicylaldehyde‐5‐sodium sulfonate with tyrosine (HPST). The internal formed ligand coordinated to Cu2+ ion in an aqueous media affording new Cu (II)‐complex (Cu‐PST), which characterized by various physico‐chemicals spectral tools. The mononuclear complex was evaluated as a homogeneous and heterogeneous catalyst in the (ep)oxidation protocols of 1,2‐cyclooctene and benzyl alcohol. Heterogeneously, Cu‐PST was immobilized on Fe3O4‐SiO2, as nanoparticles. The heterogeneous catalyst was characterized by infrared, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, energy‐dispersive spectroscopy, Brunauer−Emmett−Teller and magnetism. Homogeneously, the temperature, solvent and oxidant influences were examined in the catalytic reactions to realize the best reaction conditions. Cu‐catalyst exhibited better catalytic performance in the (ep)oxidation processes homogeneously than that in the heterogeneous phase at 80°C for 2 hr in acetonitrile. Reusability of the homogeneous catalyst was for a maximum of three times in the (ep)oxidation reaction, whereas the heterogeneous catalyst was active for six times. A mechanistic pathway was proposed for both catalysts, comparatively.
