Abstract

3-methoxy-4-(1-phenyl-1H-benzimidazol-2-yl)phenol (MPBP) was synthesized by adding N-phenyl-o-phenylenediamine, 4-hydroxy-2-methoxybenzaldehyde and ammonium acetate in the presence of ethanol and nano silica at 80 °C. Newly synthesized benzimidazole was characterized by proton NMR, carbon NMR, LC-Mass spectral studies and elemental analysis. Nickel alloys play a major role in fields like automobiles and ship building owing to their stability in Acid, Base and Saline environments. CNT’s are having high stability against corrosion. So it has been planned to prepare 3-methoxy-4-(1-phenyl-1H-benzimidazol-2-yl)phenol-functionalized carbon nanotubes for corrosion-inhibiting barrier layer on nickel alloy surfaces. The evidence of corrosion inhibition efficiency of 3-methoxy-4-(1-phenyl-1H-benzimidazol-2-yl)phenol-functionalized carbon nanotubes coated on nickel alloys was confirmed by FTIR spectral studies (essence of spectra need to include). The nature of inhibition of corrosion was determined using electrochemical methods. 3-methoxy-4-(1-phenyl-1H-benzimidazol-2-yl) phenol functionalized CNTs displayed excellent corrosion inhibition on the nickel alloy surface.
