Process for separating an ester of a monoethanoid fatty acid

摘要

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