FIELD: metal corrosion.
SUBSTANCE: protecting metals from corrosion using inhibitors used to protect various equipment made of copper and its alloys. 3.3'-(alkanediyldisulfandiyl)bis(5-amino-1H-1,2,4-triazole) is used as a corrosion inhibitor for copper and copper-containing alloys' of the general formula
where n represents a multiple of 1 to 3.
EFFECT: high degree of protection of copper and copper-containing alloys, equal to 92-99%, according to gravimetric tests in 1 wt.% HCl solutions, as well as in increasing the time of occurrence of corrosion spot in salt fog to 64-192 hours when using 3. 3'-(alkanediyldisulfandiyl)bis(5-amino-1H-1,2,4-triazoles) in a concentration of at least 0.10 mmol/dm-3.
