The article presents the results of gravimetric anticorrosion studies of 1-alkenyl-2-propargyloxy- and 1-alkenyl-2-propargyloxy-3-aminomethylbenzenes on Ct.3 steel in water- salt and hydrocarbon media saturated with hydrogen sulfide (500 mg/L), as well as the study of their bactericidal properties against sulfate-reducing bacteria. The dependence of the protective properties of these compounds on their structure was revealed. It has been established that 1-propenyl-2-propargyl-3-diethylaminomethylphenol has the best properties. At the concentration 50 and 100 mg / L in an aggressive, saturated H₂S environment, 3% aqueous solution of NaCl and kerosene (9:1 vol), the degree of protection of St.3 steel against corrosion is 94.7 and 97.5%, (at 25⁰C) and 88.0 and 94.6% (at 40⁰C), respectively.The studied compounds also have bactericidal properties, especially compounds containing in the structures, in addition to the alkenyl and propargyl substituents, also a morpholinomethyl fragment. At its concentration 50 and 100 mg/L, the degree of protection is 96–100%.
