One of the effective methods for improving the protective properties of fuels is the use of corrosion inhibitors suitable for this particular purpose. In the reported experiments, the following additives were investigated: BMF corrosion inhibitor, MSDA-11 preservative additive, and a batch of mixed additive consisting of KhT-3, KINK-1, and KINK-5, which are respectively the dimethylolurea ester of alkylbenzenesulfonic acids, an ionic complex of distilled naphthenic acids with ethylenediamine, and a similar complex with triethylenetetramine. The mechanism of additive protective action includes two stages: Displacement of water or aggressive electrolyte (such as seawater) from the metal surface, and the formation of absorbed or chemisorbed protective films on the water free metal. Both stages of corrosion protection by inhibitors were investigated. Test data are presented which show that relative polarization resistance (RPR) of KINK-1 and KINK-5 is high and that the retardation of electrochemical corrosion processes by these additives is effected primarily through the activation component of the protective action, in connection with the high energy of their absorption and with the probable formation of chemisorbed protective films.
