Abstract
The corrosion inhibitive efficiencies of two crown type polyethers, namely dibenzo-bis-imino crown ether ( C-1) and dibenzo-diaza crown ether ( C-2), which are macrocyclic Schiff base and its reduced form (macrocyclic amine), respectively, for the steel in 1 M H 2SO 4 have been investigated by Tafel extrapolation and linear polarization methods. Corrosion and adsorption isotherm parameters were determined from current–potential curves. The studies show that C-1 and C-2 inhibit the corrosion of the steel in H 2SO 4 solution. Semiempirical AM1 method was used for theoretical calculations. The obtained results of these calculations for the compounds were found to be consistent with the experimental findings.
