FIELD: metallurgy.
SUBSTANCE: invention relates to protection of metals from corrosion using inhibitors and can be used for protection of various equipment made from copper and its alloys. Corrosion inhibitor contains a heterocyclic organic compound of class of azoles, wherein active substance is 5-substituted analogue of 3-amino-1,2,4-triazole of formula I:
,
where R is a substitute selected from methyl-, ethyl-, propyl-, butyl-, pentyl-, hexyl-, heptyl-, benzyl-, methylmercapto-, ethylmercapto-, propylmercapto-, butylmercapto-, pentylmercapto-, hexylmercapto-, heptylmercapto-.
EFFECT: effective reduction of corrosion of copper and its alloys.
