Mass loss and thermometric methods have been used to study the corrosion inhibition of aluminium in HCl solution by nitrogen containing ligands viz. N-(4-N,N-dimethyl - aminobenzal)-p-anisidine (SB1), N-(4-N,N-dimethylaminobenzal)-p-toluidine (SB2) and N-(4-N,N-dimethylaminobenzal)-2,4-dinitroaniline (SB3). Results of inhibition efficiencies obtained from these two methods are in good agreement and have been found to be dependent upon the concentration of inhibitors as well as concentration of acids. Inhibition efficiency of synthesized ligands has also been studied in the presence of KCl with inhibitors.
