(57) Abstract: A method for producing a carboxylic acid from an unsaturated fatty acid and / or a derivative thereof is provided. SOLUTION: The unsaturated fatty acid in the form of acid and / or ester is combined with hydrogen peroxide in the presence of a metal oxide or a carboxylic acid, optionally with a ruthenium-based catalyst. The step of reacting nitric acid with the reaction mixture resulting from the preceding step in the presence of a vanadium-based catalyst, optionally in combination with a cocatalyst, to react nitric acid, And then-a method for producing mono- and dicarboxylic acids from unsaturated fatty acids and / or their derivatives, characterized in that it comprises a step of recovering the mono- and dicarboxylic acids. |
