ABSTRACT:
A method of preparing carboxylic acids or esters thereof by the oxidative cleavage of unsaturated fatty acids or esters thereof is carried out in a two-phase aqueous-organic system in which the organic phase contains the unsaturated fatty acid and/or the esters thereof and the aqueous phase contains hydrogen peroxide. The oxidative cleavage is carried out in the presence of a catalytic system including a catalyst belonging to the group constituted by tungstic and molybdic acids and alkaline salts thereof, and an onium salt which acts as a phase-transfer agent for the catalyst, and has the formula:
