Adsorption Films of N-Hydroxyalkylated Ammonium Salts under Conditions of Hydrogen Sulfide Corrosion

Abstract

Inhibitors of hydrogen-sulfide corrosion, namely, N-hydroxyethylated ammonium salts of some organic acids, form protective films at Cт3 steel (Z = 95 to 97%). Adsorbed and polymolecular layers of these films were revealed by electron microscopy and x-ray photoelectron spectroscopy. It was shown that the polymolecular layer can compensate for losses of the inhibitor from the sorbed layer.
