Abstract: Amides of ethylendiaminetetraacetic acid synthesized by interaction it with monoethanolamine (MEA) and diethanolamine (DEA) in various mol ratio (1:1-3). Obtained amides were investigated and confirmed by IR, and 10% solutions of their Na+, K+ salts prepared for establishing their anticorrosion activity. 10% solutions of synthesized salts were prepared for study as corrosion inhibitors in H2S condition on the steel plate. It was determined that Na+, K+ salts of amides obtained by interaction of EDTA with MEA in 1:2 mol ratio and Na+, K+ salts of amides obtained by interaction of EDTA with DEA in 1:1 molar ratio shows the best anticorrosion activity at concentation 200 mg/l and protection effect was 97% and 97,6%.

Key words: ethylendiaminetetraacetic acid, monoethanolamine, diethanolamine, H2S corrosion, protection effect.
