Abstract

Synthesis, adsorption and corrosion inhibiting effect of new nonionic surfactant consisting of 3-[(4-Dimethylamino-benzylidene)-amino]-4-hydroxy-benzenesulphonic acid as hydrophobic part and poly ethylene glylcol (poly ethylene oxide) on steel in 1.0 M HCl was investigated using weight loss and potentiodynamic polarization techniques. The experimental findings revealed that this compound inhibited the corrosion reaction in 1.0 M HCl environment. The results indicated that this surfactant was adsorbed on the metal/solution interface. A theoretical study of the adsorption behavior of this compound was carried out in the framework of the semiempirical (SE) and molecular dynamics (MD).
