  • Patent number: 5714623
    Abstract: A process for the preparation of carboxylic acids and esters thereof, which involves the steps of (a) mixing an unsaturated fatty acid or corresponding ester with an oxidative substance in the presence of a catalyst selected from the group consisting of oxides of tungsten and molybdenum and their acids and alkaline salts, (b) reacting the product mixture from step (a), which comprises vicinal diols, with oxygen or an oxygen-containing gas in the presence of a cobalt-containing compound which acts as a catalyst. The product mixture from step (a) is not subjected to any purification treatments prior to undergoing step (b).

  • Patent number: 5336793
    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:(R.sub.2 R.sub.3 R.sub.4 R.sub.5 M).sup.+ Y.sup.-in which R.sub.2, R.sub.3, R.sub.4 and R.sub.5 represent hydrocarbon groups of which at least one must have more than 10 carbon atoms,M is N or P, andY.sup.- is an inorganic anion.
