Abstract :
Corrosion inhibition of mild steel in 2N HCl medium in presence of newly
synthesized organic compounds, 2-chloroquinoline-3-carbaldehyde (FQ), [(1Z)-(2-chloro
quinoline-3-yl) methylene)] hydrazone (FQMH), 2-6- Bis- {(2-chloro quinoline-3ylmethylene}-
amino}-hexanoic acid (FQHA) and (3Z)-4-(2-chloro quinoline-3-yl)-2-(mercapto
methyl)but-3-enoic acid (FQBA) were investigated by weight loss and galvanostatic
polarisation techniques. Effect of concentration, time of immersion and temperature effect on
corrosion inhibition efficiency was evaluated. The inhibiting performances of all the
compounds were found to increase with the increase in concentrations.
