Abstract : Abstract Propionitrile (PN), succinonitrile (SN), acrylonitrile (AcN) and benzonitrile (BN) have been studied as corrosion inhibitors for mild steel in 1.0 M H2SO4 using gasometry, mass loss and potentiodynamic polarization techniques. Inhibitor efficiencies and the adsorption isotherms were calculated from the geometry measurements. The effect of structural changes in these compounds on their inhibition efficiency has been studied. Polarization curves indicated that these compounds affect both the cathodic and anodic over-potentials with a more pronounced effect of the cathodic curves. Mass loss measurements at six temperatures ranging from 25 to 50ₒC indicated that the apparent activation energy of the dissolution of steel in 1.0 M H2SO4 in presence of nitriles increases slightly than that of uninhibited solution. The results obtained from gasometry, polarization and mass loss measurements indicated that the inhibiting action of the nitriles occurs by simple blocking of the available surface without affecting the reaction mechanism.
