1,4-benzoquinone derivatives as inhibitors of corrosion and hydrogen absorption of steel at presence of SRB

The results of study of the derivatives of 1,4-hydroquinone as inhibitors of microbiological corrosion and hydrogen absorption of mild steel in a water-salt media supporting the development of sulphate reducing bacteria (SRB) and close by its composition to the sea water containing biogenic hydrogen sulphide. Content of H$_2$S, bacterial titre in the corrosive meas well as its pH, E$_h$ and potential of steel $\varphi,$ were determined together with the quantity of hydrogen absorbed by surface layers of steel. Protective efficiency of the best studied species from corrosion reaches 65...84 %, as for their action against hydrogen absorption by steel specimen – 60...72 %. The decrease of the number of SRB cells due to the action of the derivatives of 1,4-hydroquinone was found to be 48...84 %, while the suppression degree – 29...57 % (at the concentration of 5 mMol/L).
