2260. MICHAEL, J. M., AND HAGER, K. F. Corrosion-Inhibited Fuels. Ind. Eng. Chem., vol. 41, 1949, pp. 2616-2622. Methods for preventing corrosion in pipelines, storage containers, tanks, and other equipment in contact with fuels even under severe conditions are surveyed. Of the possibilities investigated, only the admixture to the fuels of corrosion inhibitors to produce surface passivity offers extended technical application and enough endurance in practical use. The data presented show that fuels inhibited by hydrocarbon-sulfamido-carboxylic acids offer the greatest advantage. Extensive investigations on emulsifying agents led to the surprising result that, without regard to the construction materials used, even a small addition of the Na salt of Mepasin-sulfamido-acetic acid to the fuel prevents any corrosion. Mepasin is a high-boiling fraction of the hydrocarbons obtained by the Fischer-Tropsch synthesis having a chain length of about 12-18 C atoms. A mixture of about equal parts of Mepasin-sulfamido-sodium acetate and unchanged Mepasin is a very efficient emulsifier known in Germany under the trade name Bohrmittel Hoechst. |
