Title : ( In Situ Synthesis of 2-Phenylbenzimidazole as an Hydrogen Sulfide Corrosion Inhibitor of Carbon Steel )
Authors: Shabnam Pournazari , Mohammad Hadi Moayed , Mohammad Rahimizadeh ,Abstract
Hydrogen sulfide corrosion inhibition of carbon steel has been evaluated using the combination of benzene-1,2-diamine, benzaldehyde, and FeCl3 to in situ inhibitor synthesis at 25°C using electrochemical and weight-loss studies. The results showed that the corrosion rate of steel decreased significantly by increasing the inhibitor concentration. The concentration of in situ synthesized inhibitor was measured by ultraviolet and visible spectrophotometer (UV-vis). The morphology and composition of the corrosion products were analyzed using scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS). Fourier transform infrared spectroscopy (FTIR) demonstrated the formation of 2-phenylbenzimidazole on the surface by an in situ manner. Quantum chemical studies were applied to investigate the correlation between the molecular structure and inhibition effect of this compound.
