Abstract

Three novel Schiff base based cationic surfactants, namely, (E)-3-(decylideneamino)-N,N,N-trimethylpropan-1-aminium methyl sulfate (DSMS), (E)-N-(3-(decylideneamino)propyl)-N,N-dimethylbutan-1-aminium bromide (DSBB) and (E)-3-(decylideneamino)-N-ethyl-N,N-dimethylpropan-1-aminium iodide (DSEI) were synthesized and their chemical structures were assessed. The surface activities of the target prepared surfactants were investigated. Based on gravimetric, gasometric and electrochemical techniques, their inhibition impact on aluminum corrosion in solution with 0.5 M HCl was studied. The effect of raising both temperature and surfactant concentration on the inhibition efficiency was studied and the thermodynamic functions were measured and discussed. Langmuir adsorption isotherm fitted widely with the empirical data.
