Electric Literature of C12H9N3. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Performance and theoretical study on corrosion inhibition of 2-(4-pyridyl)-benzimidazole for mild steel in hydrochloric acid.
Inhibition performance of 2-(4-pyridyl)-benzimidazole (PBI) against corrosion of mild steel in 1.0 M HCl was studied by weight loss and electrochem. measurements. The inhibition efficiency increased with increasing inhibitor’s concentration, but decreased with the increase in temperature and concentration of the acid. The theor. results from DFT and MD simulations reveal that adsorption of PBI depends on the formation of coordinative bonds between PBI mol. and Fe surface, and the binding energy between PBI mol. and Fe surface is the highest among the three studied compounds
