STABILISING FUEL ADDITIVE, PRODUCTION METHOD THEREOF AND COMPOSITION CONTAINING SAID ADDITIVE Russian patent published in 2011 - IPC C10L1/188 

FIELD: chemistry.

SUBSTANCE: additive is a solution of an equimolecular mixture of unsaturated fatty monocarboxylic acid with 18-20 carbon atoms with alkanolamine in a fuel-compatible organic solvent. Components are in the following ratio in wt %: equimolecular mixture of unsaturated fatty monocarboxylic acid with alkanolamine 10-60, organic solvent 40-90. The additive is obtained by mixing unsaturated fatty monocarboxylic acid with alkanolamine, taken in equimolecular ratio, in the medium of a fuel-compatible organic solvent at room temperature. The fuel composition contains gasoline, the stabilising additive and the fuel-compatible organic solvent, corresponding to the solvent in the additive. Components are in the following ratio in wt %: stabilising additive 2.0-13.0, organic solvent 5.0-10.0, gasoline - the rest.

EFFECT: stabilising additive provides phase stability of waterlogged fuel, has anti-corrosion activity, and increases octane number of gasoline and antiknock rating.
