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; characterised 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.
A method of oxidative molecular cleavage of a fatty compound selected from the group formed of unsaturated aliphatic carboxylic acids, esters of an unsaturated aliphatic carboxylic acid, epoxidized aliphatic carboxylic acids, esters of an epoxidized aliphatic carboxylic acid, hydroxylated unsaturated aliphatic carboxylic acids, and esters of a hydroxylated unsaturated aliphatic carboxylic acid, wherein:
