Synthesis of Hydrogen Sulfide Corrosion Inhibitors for Oil Production

摘要

Pyridinium salts have been synthesized by reacting 2-allyl- and 4-propenylphenoxy(C2—C4)bro-moalkanes 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-propenylphenoxytetamethyl-ene)pyridinium bromide exhibits the best inhibitory properties (degree of corrosion protection at a concentration of 100 mg L~(-1) is 96.0%).
