Pyridinium salts have been synthesized by reacting 2-allyl- and 4-propenylphenoxy(C-2-C-4)bromoalkanes with pyridine and further examined as inhibitors of hydrogen sulfide corrosion of St3 steel in water-salt systems containing H2S. The dependence of the protective properties of the test compounds on their structure has been revealed. It has been found that N-(2-propenylphenoxytetamethylene)pyridinium bromide exhibits the best inhibitory properties (degree of corrosion protection at a concentration of 100 mg L-1 is 96.0%).
