Abstract
It was found that the conversion (by isomerisation or branching) of unsaturated fatty acids into branched fatty acids can be catalysed by materials having a microporous structure. Such a process gives high conversion rates and a high selectivity towards branched fatty acids, whilst a low amount of undesired by-products is obtained. Zeolites are preferred materials for catalysing said reaction.
