Abstract
Procedure for the purification of mixtures of fatty acids or their esters, from the most unsaturated parts, characterized in that the mixtures are heated in the presence of montmorillonite-type bleaching earth catalysts with a specific surface area of more than 150 m2 per gram, preferably 200-250 m2 per gram, at temperatures between 110 to 210ºC, preferably 140-180ºC and are then separated by distillation.
