The current investigation presents the corrosion activity of Elaeoselinum thapsioides (BEET) butanolic extract in 1 M HCl as a novel green source of corrosion inhibitor, and it's synergetic effect with another butanolic extract of Reutera lutea (BERL), whose belongs to the Apiaceae family. Weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements have been done to study the inhibition efficiency. The obtained results showed that the inhibition efficiency of BEET alone increase with concentration and reached a value of 82% at 900 ppm. However, the maximum protection efficiency was more than 92% with the combination of BEET and BERL inhibitors. The rise of temperature caused a significantly decreased of inhibition efficiency. The potentiodynamic polarization results revealed that the extract functions as mixed-type inhibitor with predominance at anodic domain, and the adsorption process of the extract follows Langmuir isotherm. In addition, EIS shows that increasing the concentration of the inhibitor leads to an increase of the charge transfer resistance and reducing the double layer capacitance. The synergistic factor (S) was used to investigate the synergistic behavior of the selected inhibitors.

“…By inspection of Figure 3, we could observe that BAP adsorbs close to Fe (100) surface, a chemical interactions can possibly occur through reactive sites in the molecule and on the metal surface. In this case, BAP molecule protects the steel surface from the aggressive medium by adsorbing on the Fe (100) surface in a planar form [34]. The higher value of binding energy suggests easier adsorption of inhibitor on the Fe (100) surface [35].…”

A new inhibitor, N-m-benzylamine-4-(4-hydroxybut-2-ynyl) pyridinium bromide (designated as BAP) was designed and synthesized. Quantum chemical calculation and molecular dynamics (MD) simulations manifested that BAP, a compound by covalent combination of 4-(4-hydroxybut-2-ynyl) pyridine (HYP) and 3-methyl benzenamine (MBA), functioned better than did the two moieties (HYP and MBA) for X70 steel corrosion inhibition. The corrosion inhibition investigation revealed that the experiment outcome was in good consistency with the theoretical calculation. The inhibition efficiency of BAP was 95.72% for X70 steel in 5 M HCl at 90 0C. BAP adsorbed on X70 steel surface, obeyed Langmuir isotherm, retarded both the metal dissolution and the hydrogen evolution, and enhanced greatly the acid corrosion resistance of X70 steel. Comparative test demonstrated that the inhibition efficiency of BAP was about 10 times of that for MAB and 8 times of that for HYP albeit the concentration of BAP was tenth of that of HYP and MBA. The experimental investigation backs up the theoretical calculation and manifests intramolecular synergism of the structure moieties being beneficial to design of high effective inhibitors.
