Abstract: 
Aminooxoethylpyridinium chlorides under the St3ps steel corrosion in acid hydrochloric and sulfuric solutions demonstrate the inhibition efficiency at 98 %. The compound with hydrazinocarbonyl and 2,3-dimethylphenyl fragments turns out to be the most effective within the interval 293–333 К. This inhibitor is also characterized by a significant aftereffect due to the chemisorption on the steel surface.
