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).
