The present invention is directed to a process for synthesizing an internal ketone K1 by decarboxylative ketonization reaction of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in a reaction medium, said process being characterized in that a ketone K2 at liquid state, which is identical or similar to the ketone K1, is introduced into the reaction medium. The so-synthesized internal ketone K1 can be used for the preparation of a variety of end compounds, including surfactants having a twin-tail structure or a Gemini structure.
