Abstract
The invention relates to a non-catalysed method for the synthesis of straight-chain aliphatic carboxylic acids by oxidation of straight-chain aldehydes with oxygen-containing gas mixtures. The invention is characterised in that during the novel process of oxidation branched aldehydes are present in the reaction mixture.
