Abstract
A process for separating a blend of saturated and unsaturated fatty acids or saturated and unsaturated fatty acid alky esters into a first fraction enriched with the saturated fatty acids or saturated fatty acid alkyl esters and a second fraction enriched with unsaturated fatty acids or unsaturated fatty acid alkyl esters. When separating fatty acids, the process includes the steps of (a) saponifying a blend of long chain saturated and unsaturated fatty acids to form free fatty acids, (b) complexing the free fatty acids with urea, and (c) separating the urea complexed free fatty acids into a first fraction enriched with saturated free fatty acids and a second fraction enriched with unsaturated free fatty acids. When separating fatty acid alkyl esters, the process includes the steps of (i) complexing the fatty acid alkyl esters with urea, and (ii) separating the urea-complexed fatty acid alkly esters into a first fraction enriched with saturated fatty acid alkyl esters and a second fraction enriched with unsaturated fatty acid alkyl esters.
