“…However, the SEM–EDS analysis in CI presence evidenced localized corrosion on the API X60 steel passive film. Likewise, Díaz et al 118 analyzed carboxyethylimidazoline as CI for API X120 steel in H 2 S ( Table 7 ). The authors reported the reduction of the polarization resistance in the presence of carboxyethylimidazoline with an IE max of 97% (160 μmol L –1 ).…”

In this work, we systematically investigated the effect of four bis(benzimidazole) derivatives containing different heteroatoms in molecular structures on inhibiting corrosion of N80 steel in 0.5 mmolÁl À1 H 2 S solution by potentiodynamic polarization, electrochemical impedance spectroscopy and metallographic microscope. The results showed that within the range of 0.1-1.0 mmolÁl À1 , the adsorption of bis(benzimidazole) derivatives on N80 steel surface was found to follow Langmuir adsorption isotherm. Meanwhile, stable adsorbing monolayer between inhibitors and the metal surface was formed, which was confirmed by thermodynamic adsorption parameters (K ads , ΔG 0 ads ). This series of bis(benzimidazole) derivatives exhibited obvious corrosion inhibitory properties for N80 steel. Moreover, they could both slow down the anodic dissolution of iron and the cathodic reduction reaction as mixed type corrosion inhibitors. The optimal inhibition efficiency was obtained for 1,3-bis(benzimidazl-2-yl)-2-thiapropane (BBMS). Hopefully, this series of inhibitors might find applications in anti-corrosion and many other areas.
