FIELD: chemistry.
SUBSTANCE: invention relates to corrosion protection of low-carbon steel during etching for removal of industrial scale in machine building and instrument making. Disclosed is the use of N-allyl-2-amino-5-phenyl-1,3,4-thiadiazole, having the formula
,
in the concentration range of 0.05-0.5 g/l in 5% aqueous solution of hydrochloric acid at temperature 25 °C as a corrosion inhibitor of steel St3.
EFFECT: reduced corrosion rate of low-carbon steel, as well as wider range of possible compounds which inhibit corrosion of steel.
