Inhibitive effect of schiff bases on corrosion of mild steel in hydrocloric acid solution / Mohd Shahril Anoar
The syntheses of Schiff base compounds using 4-hydroxybenzaldehyde and 4-chlorobenzaldehyde with N-phenyl-1,4-phenylenediamine have yielded two green semi-crystalline compounds. The characterization of the compounds is performed by infrared spectroscopy, NMR spectroscopy and elemental analysis. All...

The 4-hbnp reaches maximum inhibition efficiency (91.20 %) at 1 x 10⁻² M whereas 4-cbnp reaches the highest inhibition efficiency (95.37 %) at 1 x 10⁻² M. It is suggested that the corrosion inhibition on mild steel through adsorption is affected largely by the anchoring factor which seems to have played a more prominent role in the inhibiting property of the Schiff bases than the π-ring factor.
