Abstract
A method for the purification of mixtures of fatty acids or fatty acid esters containing polyunsaturated components by heating the mixture in the presence of an organic macroporous, acid ion exchange resin having a specific surface area of at least 35 m.sup.2 /gm and devoid of gel characteristics, and then separating the purified mixture by distillation. The method is especially useful for the production of oleic acid which is relatively free of linoleic acid.
