This study aims at evaluating the inhibition efficiency of two different hop cones and analyzing their adsorption properties on the surface of steel components that actually comprise hop cones. By employing weight loss and potentiodynamic polarization methods, we compare volatile fractions of "Aromatic" and "Bitter" hop cones. We analyze the adsorption ability on the surface of steel components that comprise hop cones using quantum-chemical calculations. We show that the inhibition efficiency of both varieties under study do not significantly differ, though with quite a large difference by genotype, and provide effective corrosion protection of carbon steel at the periodic condensation. The experimental results demonstrate that the investigated izopropanol hop extract, which can effectively retard the anodic dissolution of steel. [ABSTRACT FROM AUTHOR] |
