In published scientific work presents the simulated environment in the quantum chemistry package HyperChem version 8.0.9 using semiempirical method ZINDO/1 the adsorption process of organic compounds of the class of sulphidefenols, on iron atoms (available in tested steel grade in the amount of 97%). The scientific novelty of the research is to move away from the technology cluster simulation and attracting more informative approximation to donor-acceptor interaction of organic compounds with the iron atoms. This approach, as will be shown, with high accuracy reflects the process of galvanic corrosion protection in water-salt corrosive environments, simulating sea water, by electrochemisorption test as a corrosion inhibitor organic compounds on the metal surface with the formation of complex compounds. In the research process were obtained and analyzed: the composition of the complexes (ironsulphidefenols), a graph showing the dependence of the local electrophilicity the sulfur atom, the magnitude of the protective effect (inversely proportional to corrosion rate).
