Abstract
A study was carried out of the anti-corrosion effect of two acids on St3 steel: nitrilotrimethylenephosphonic (NTP) and oxyethylidenediphosphonic (OEDPA), in combination with monoethanolamine. The dependence of the inhibitory effect of NTP and OEDPA complexes with monoethanolamine on their concentration in solution was studied. The possibility of their use as corrosion inhibitors of low-carbon steel has been shown.
