The efficiency of N-(2-hydroxyphenyl)salicyaldimine (1), N,N'-bis-(salicyaldehyde)-1,3-diaminopropane (2) and N,N'-bis-(2-hydroxybenzyl)- 1,3-diaminopropane (3), derived from the reduction of N,N'-bis-(salicyaldehyde)-1,3-diaminopropane (2), as corrosion inhibitors has been studied. Weight loss, polarization and electrochemical impedance spectroscopy experiments have shown the reduced compound 3 to be the best amongst the compounds studied. (C) 2003 Elsevier B.V.
