A process for separating an ester of an unsaturated fatty acid from a mixture comprising an ester of an unsaturated fatty acid and an ester of a saturated fatty acid which process comprises contacting the mixture at adsorption conditions with an adsorbent comprising a X or a Y zeolite containing one or more selected cations at the exchangeable cationic sites thereby selectively adsorbing the ester of an unsaturated fatty acid. Preferably the ester of an unsaturated fatty acid will be recovered from the adsorbent by desorption with a desorbent material. |
