Abstract The mechanism of corrosion-inhibiting action of benzeneacetonitriles was investigated by measuring the corrsion rates with gravimetrie method.The effect of introducing different funetional groups into the para-position of the benzene ring and an isopropyl in the α-position on the inhibiting efficiency is discussed. The analysis of the kinetics of dissolution of steel in HCl solution and the characteristic relationship between the inhibiting efficiency and temperature suggests that chemisorption is the mechanism of the inhibiting action of benzeneacetonitriles.Introducing electron-donating groups into the para-position increases the inhibiting efficiency while introducing electron-withdrawing groups into the para-position decreases the inhibiting efficiency.An isopropyl group in the α-position will either raise or reduce the inhibiting efficiency.
