  • Method of oxidative molecular cleavage of a fatty compound
    Patent number: 9090552
    Abstract: A method of oxidative molecular cleavage of a fatty compound, includes:—forming a liquid composition, referred to as a fatty composition, consisting of at least one aliphatic carboxylic acid, the fatty composition including the fatty compound; characterized in that it then involves:—adding, to the fatty composition, a solution of at least one quaternary ammonium salt in water capable of forming an emulsion from the fatty compound and water, then;—adding, to the emulsion, a liquid solution of at least one tungstophosphoric acid in a composition including hydrogen peroxide (H2O2), in such a way as to form, in situ in the emulsion, a quantity of a phase-transfer catalyst, formed from tungstophosphoric acid and at least one quaternary ammonium from the quaternary ammonium salt(s), and to allow the oxidative molecular cleavage of the fatty compound.
