A relationship between the adsorption of polar organic compounds on metal and their ability to inhibit corrosion in sea water were examined. As corrosion inhibitors of ferrous metal such compounds with straight hydrocarbon chains of 16 carbon atoms, as acid amide, acid, alcohol, and amine were tested, resulting the amide the best and the amine the second. Amide group shows increased adsorption as they have equal extent of covering effects of their alkyl groups. Our inhibitors (amine-acid complexes) show resembling behaviors with the amide to inhibit corrosion of metal.
High molecular weight S-containing organic compounds seem to be effective in inhibiting corrosion of copper in sea water.
