Abstract: Corrosion inhibition efficiency of unusual phenyl alanine derivatives (substituted in the phenyl ring and double bond in the side chain) were investigated in neutral aqueous solution by weight loss test and by atomic force microscopy. The influence of the substituents in the phenyl ring as well as of the double bond was elucidated and explained. The effect of electrophilic or nucleophilic groups in the phenyl ring was demonstrated by efficacy and roughness parameters

Keywords: phenylalanine derivatives, corrosion inhibitor, nucleophilic and electrophilic substituents in the phenyl ring, double bond
