New nitrogen- and sulphur-containing derivatives of alkoxymethylvinylcyclohexane have been synthesized. The compounds obtained have exhibited great effectiveness as corrosion inhibitors of St3 steel in a concentration of 750 mg/l. The highest protective action is possessed by 1-vinyl-3-(2-butylthioethylamino)4-nonyloxymethylcyclohexane, which gives grounds for recommending it for the anticorrosion protection of steel under hydrogen sulphide corrosion conditions.
