“…In addition to its good corrosion resistance in the atmosphere and among aqueous medium (Kaufman, 2000;Yuan‐Ting et al, 2017) since it forms a resistive oxide layer on its surface protects it from corrosion but this layers in chloride containing solution, alkaline, and acidic medium destroyed. Several methods have been used to stifle the corrosion of aluminum in acidic media, the most applicable method is the use of organic compounds (Abdallah et al, 2018b; Li et al, 2011, 2014; Safek et al, 2012; Solmaz et al, 2008; Zapta‐Loria and Pech‐Canul, 2014); as they form an adsorbing layer on the metal surface protecting it from the corrosive solutions (Abdallah et al, 2018a; Al‐Khaldi and Al‐Qahtani, 2013; Lece et al, 2008). However, most of these compounds have damaging effects on human health and the atmosphere.…”

Two series of eco‐friendly nonionic anionic surfactants based on itaconic acid and 1, 6 hexane diol were synthesized. The chemical structures of the prepared surfactant were confirmed by FTIR and 1H NMR spectroscopy. The prepared surfactants were evaluated to prevent the corrosion of aluminum in 1.0 M HCl solution by electrochemical and chemical methods. The data obtained showed that the prepared compounds have good inhibition efficiency (IE%) even at 10−5 M concentrations and act as mixed‐type inhibitors, they do not affect the mechanism of the electrode processes, as well as the IE% increase by increasing the concentrations of the inhibitors, immersion time, and hydrophilic chain length. The high inhibition efficiency is due to the adsorption of the inhibitors molecules on the metal surface and the formation of a protective film. The surface activities of these compounds were also investigated and were correlated to their inhibition efficiencies and chemical structure. Through studying biodegradability of the synthesized surfactants we find that they are readily biodegradable in the environment and thus they are considered as eco‐friendly corrosion inhibitors. Finally, the effect of the addition of these compounds on the aluminum surface was identified by atomic force microscopy (AFM) technique.
