The data on adsorbability of oleamides and hexylamine, cyclohexylamine, morpholine, piperidine, and piperazine salts of oleic acid are systematized in this study. The protective mechanism of these compounds is studied in order to reveal a correlation between the inhibiting ability and the calculated parameters of the molecules. A procedure for measuring the Volta potential difference using a Poverkhnost-II high-sensitivity digital electrometer under the conditions when water- and hydrocarbon-soluble corrosion inhibitors interact with the steel and copper surface is elaborated. It has been proven that a high-efficiency corrosion inhibitor can be designed based on the data on its donor properties and adsorbability.
